Should be perfectly compatible with the Arduino supported functions. Compiler different as noted in p#22 with the var types/sizes used for indexing and counts.

The pjrc.com/teensy/td_libs_EEPROM.html does say: Please refer to the official EEPROM library documentation for more details.

If it doesn't work the same it is a Teensy bug. But, need to have a simple example showing it reproducing the problem in the Teensy EEPROM code.

Yes I assume that they use the same API. EESPROM.write(key, value);

However the underlying implementation may be very very different. So if you are optimizing around theirs it could do very different things.
During T4 beta we were debugging some of the EEPROM code, so for example I still have this test sketch lying around:

Code:

#define MAX_INDEX 256
uint8_t inc_value = 0;  // default to just index...
#include <EEPROM.h>
void setup() {
  // put your setup code here, to run once:
  while (!Serial) ;
  pinMode(LED_BUILTIN, OUTPUT);
  Serial.begin(115200);
  Serial.println("EEPROM Test");

}

void loop() {
  int ch;
  // lets try writing to EEPROM
  uint16_t max_index = EEPROM.length();
  if (max_index > MAX_INDEX) max_index = MAX_INDEX;
  Serial.printf("EEPROM length: %d Max Test: %d Inc: %d\n", EEPROM.length(), max_index, inc_value);
  Serial.flush(); // Make sure the output is out
  uint32_t start_time = micros();
  for (uint16_t i = 0; i < max_index; i++) {
    EEPROM.write(i, (i + inc_value) & 0xff);
  }
  Serial.printf("Write time: %d\n", micros() - start_time);
  Serial.println("Start read back");
  start_time = micros();
  for (uint16_t i = 0; i < max_index; i++) {
    uint8_t b = EEPROM.read(i);
    if (b != ((i + inc_value) & 0xff)) {
      Serial.printf("Read mismatch: %d %x!=%x\n", i, b, (i + inc_value) & 0xff);
    }
  }
  Serial.printf("Read time: %d\n", micros() - start_time);

  uint8_t still_waiting = false;
  do {
    Serial.println("Press anykey to run again");
    still_waiting = false;
    while (!Serial.available()) {
      digitalWrite(LED_BUILTIN, !digitalRead(LED_BUILTIN));
      delay(250);
    }
    if ((ch = Serial.read()) == 'i') inc_value++;    // setup so we can increment all values...
    if (ch == 'd') {
      dump_eeprom();
      still_waiting = true;
    }
    if (ch == 'b') {
      Serial.print("Writing block 300-303 with 25 values each, start: ");
      uint8_t values[4];
      for (int i = 0; i < 4; i++) {
        values[i] = EEPROM.read(300+i);
        Serial.printf(" %2lx", values[i]);
      }
      Serial.println();
      for (int loop_count = 0; loop_count < 25; loop_count++) {
        for (int i = 0; i < 4; i++) {
          EEPROM.write(300+i, ++values[i]);        }
      }
      still_waiting = true;
    }
    while (Serial.available()) {
      Serial.read();  // discard everything
    }
  } while (still_waiting);
}
/* EEPROM start address in Flash */

#if defined(ARDUINO_TEENSY40)

void dump_eeprom() {
  // Lets print out all of the Possible EEPROM values.
  uint16_t eeprom_size = EEPROM.length();
  Serial.printf("EEPROM length: %d\nContents:\n", eeprom_size);

  // For here lets limit to first 256
  eeprom_size=256;
  for (uint16_t i = 0; i < eeprom_size; i++) {
    Serial.printf("%x:%x ", i, EEPROM.read(i));

    if ((i & 0xf) == 0xf) Serial.println();
  }
  Serial.println("\nRaw Data");

  // Now lets see if we can dump the flash sectors:
  uint32_t sector;
  uint16_t *last_indexes[256];

    const uint16_t *p_start = (uint16_t *)(FLASH_BASEADDR + sector * 4096);
    const uint16_t *p_end = (uint16_t *)(FLASH_BASEADDR + (sector + 1) * 4096);
    uint16_t *p;
    for (p = p_start; p < p_end; p++) {
      if (*p == 0xFFFF) break;
      last_indexes[*p & 0xff] = p;
    }
    Serial.printf("EEprom Page:%d addresses(%lx - %lx): first free: %x\n", sector, p_start, p_end, p);

    uint8_t count = 0;
    for (p = p_start; p < p_end; p++) {
      if (*p == 0xFFFF) break;
      uint8_t value_offset = *p & 0xff;
      uint8_t value = *p >> 8;
      uint16_t eeprom_index = (((value_offset >> 2)*FLASH_SECTORS) << 2) + (sector << 2) + (value_offset & 0x3);
      Serial.printf(" %c%03d(%02x)=%02x", last_indexes[value_offset]== p? '*' : ' ',
          eeprom_index, value_offset, value);
      count++;
      if (count == 16) {
        Serial.println();
        count = 0;
      }
    }
    Serial.println();
  }
}

Which looks like I updated for T4.1... Not yet for MicroMod.

I am not suggesting you run this, but it can be interesting at times, to extract the dump the EEPROM data. That first dumps out the values for the first 256 indexes and then dumps out the raw EEPROM sectors.

Likewise, if you look into cores\teensy4\eeprom.c you can see how the code works.
The code also has a bunch of commented out printf statements, which can be uncommented, and if core debug enabled will print stuff on Serial4...

But if you look at the Read code:

Code:

uint8_t eeprom_read_byte(const uint8_t *addr_ptr)
{
	uint32_t addr = (uint32_t)addr_ptr;
	uint32_t sector, offset;
	const uint16_t *p, *end;
	uint8_t data=0xFF;

	if (addr > E2END) return 0xFF;
	if (!initialized) eeprom_initialize();
	sector = (addr >> 2) % FLASH_SECTORS;
	offset = (addr & 3) | (((addr >> 2) / FLASH_SECTORS) << 2);
	//printf("ee_rd, addr=%u, sector=%u, offset=%u, len=%u\n",
		//addr, sector, offset, sector_index[sector]);
	p = (uint16_t *)(FLASH_BASEADDR + sector * 4096);
	end = p + sector_index[sector];
	while (p < end) {
		uint32_t val = *p++;
		if ((val & 255) == offset) data = val >> 8;
	}
	return data;
}

If you for example pass in: indexes 1-20, they will not all end up in the same FLASH page:
That is:
1 maps to (sector = 0, offset= 1
2 (0, 2), 3(0, 3)
4 (1, 0), 5(1,1), 6, 7(1, 3)
8 (2, 0)...
12(3,0), ... 15(3,3)
16(4,0)...

So 1023 (1023 >> 2) % 15 = 0 and (1023 &3) | ((1023 >>2)/15) << 2 == 3 | (255/15) << 4 == 3 | 17<<2 = 71

So 15 pages *4 = 60 do first 60 will go across the 15 pages using offset = 0-
The next 60 will again go through the 15 pages with indexes (4-7)...
Up to index 1023, which is: if I computed correctly value 71 within that page. So up to 72 possible values in that one page.

So what happens when you Read or write lets say something like: EEPROM.write(0, 42)

Is it computes which Sector it is in, each sector if 4096 bytes: And it scans from the start of the page: to the end of the page looking for
in this case the offset(0), note it will bail if it finds the logical end of that sector, looking for a 0, if it finds it, it remembers that value and continues
and returns the last match...

Writes do something similar, in that it walks that sector looking for the offset=0, and again remembers the last one... If then the last one matches the new
value is simply returns. Else it tries to append the new tuple (0, 42) to the end of that sector...

However if there is no room left in that sector, it then needs to rebuild that sector data, by going through all of the list for all of the current unique values,
that is for example if ofset=0 was written 30 times in this sector it will only keep the last one. ditto for 1... So all of the old previous values for indexes
are removed, the Flash Sector is erased and the new compressed sector written out.
So for example you only indexes 0-59, all of the pages will then typically only have 4 values in them. So you can write that one a lot of times before it has to do the
slow flash operation... But if you use all 1024 values you might saving away like 71-72 values in each sector after compressed and as such will have to flash that many more times.

Hope that makes sense.

Thanx KurtE & defragster for your answers but I don't have the courage to pursue this issue. I have a perfectly functional EEPROM wearleveling library for storing and retrieving blocks of strings on Arduino Nano. If I understand correctly it "should" be compatible with Teensy too but not so for me for now. I will leave it at that and not use it for my sensor monitor. I will remember that if I turn off the power, I will lose the displayed sensor data for up to an hour.

Running this on a T_4.1 with edited code below, and after a few edits,uploads it is working here?

Code:

void setup() {
  Serial.begin(115200);
  delay(1000);
  Serial.println("\n" __FILE__ " " __DATE__ " " __TIME__);
  //inteeprom.format_eeprom(); //needs to be formatted once
  if (inteeprom.begin()==0) Serial.println("begin() ERROR, Format the EEPROM");
[B]  //inteeprom.save_nstrings_to_eeprom(TABLESIZ,tableadr);[/B]
  Serial.println("latest 6 strings read from EEPROM");
  if (inteeprom.get_nstrings_from_eeprom(TABLESIZ,tableadr)==0) Serial.println("EEPROM is MT"); //read string
  Serial.println(eaudgc);
  Serial.println(eaucm);
  Serial.println(eautime);
  Serial.println(airdgc);
  Serial.println(airhum);
  Serial.println(airtime);
[B]  eaudgc[0]++;
  inteeprom.save_nstrings_to_eeprom(TABLESIZ,tableadr);[/B]
}

void loop() {
  // put your main code here, to run repeatedly:
}

This shows how many times it ran - the last EIGHT are the ones where code above was in use after getting the data set and code figured out.
Edited to show only the changing "eaudgc[0]++;" value:

I don't see the loop in your modified code but it seems to be working there. But sorry, it's not this sketch code included in my library that doesn't work. It's my sensor monitor program that CALLS this library and receives bad data from the EEPROM. It's too complicated and needs a receiver, tft, esp01. I'll have to write a simple EEPROM debug code using my library and run it on my Teensy 4.0. I didn't bother with this up to now because all was working fine on my Nano. But, not sure when I'll have time to do that.

You are right, it should run on a Teensy. But I believe as the code is, it is more wear producing instead of wear leveling on the Teensy. For the reasons I mentioned in previous post.
But it should work.

As I understand it, the NANO uses an 8 bit AVR (atmega328) like the Uno. These boards have a 1K EEPROM, where when you write to EEPROM(0) it writes to a specific location on the chip, and you can only reliably write to that same position so many times. Which is why the EEPROM leveling code library was created.

The Teensy does not have an EEPROM, so it is emulated by the code, to use FLASH storage to do it. Each Flash page is 4K, and in the case of T4 it uses the last 15 pages of Flash to emulate the EEPROM.

Note: T4.1 and MicroMod use 63 pages of flash, so will have slightly different behavior than T4.
Mainly as I mentioned in previous post first 60 values will spread 4 values per each of the 15 pages. And in the other two 252 values will have 4 values per page...
So again trying to level by using indexes 0-1023 will simply cause more values to be retained within each page, when it decides it needs to erase and rewrite the page when full...

A quick and dirty simple version of your library:

Code:

//#include <stringsToint_EEPROM.h>

StringsTointEEPROM::StringsTointEEPROM() {
}

void StringsTointEEPROM::format_eeprom() {
  // Don't do it...  This just does writes
  EEPROM.write(0, 0xff);  // Just write first one
}

int StringsTointEEPROM::begin() {
  return find_eeprom_address();
}

void StringsTointEEPROM::save_string_to_eeprom(char *stringIn) {
  // KISS version
  while (*stringIn) {
    EEPROM.write(_adr_EEPROM++, *stringIn++);  //write sync
  }
  EEPROM.write(_adr_EEPROM++, 0xff);  //write end of string
}

void StringsTointEEPROM::save_nstrings_to_eeprom(int nbstring, char *stringsIn[]) {
  // KISS version
  _adr_EEPROM = 1;
  for (int i = 0; i < nbstring; i++) {
    save_string_to_eeprom(stringsIn[i]);
  }
  EEPROM.write(0, nbstring);  //write end of string
}

void StringsTointEEPROM::print_strings_from_eeprom() {
  char str[256]; // Should be big enough for any of our strings.

  int nbstring = EEPROM.read(0);
  if (nbstring > 10) return ; // probably nothing valid...
  _adr_EEPROM = 1;
  for (int i = 0; i < nbstring; i++) {
    get_string_from_eeprom(str);
    Serial.println(str);
  }
}

int StringsTointEEPROM::get_string_from_eeprom(char *stringOut) {
  // KISS version
  char val;
  while ((val = EEPROM.read(_adr_EEPROM++)) != (char)0xff) {
    *stringOut++ = (char)val;
  }
  *stringOut = '\0';
  return 1;
}

int StringsTointEEPROM::get_nstrings_from_eeprom(int nbstring, char *stringsOut[]) {
  if (EEPROM.read(0)  != nbstring) return 0;// quick test if 
  _adr_EEPROM = 1;
  for (int i = 0; i < nbstring; i++) {
    get_string_from_eeprom(stringsOut[i]);
  }
  return 1;
}

int StringsTointEEPROM::find_eeprom_address() {
  _adr_EEPROM = 1;
  return 1;
}

I have not run it much, ran it with your early sketch:

Code:

latest 6 strings read from EEPROM
25
15
(05:30)
18
33
(06:30)

Again if I were doing this for real, might add in more error checking code and the like.

Or maybe even go a completely different route, like create a Littlefs_program File system on the chip and then simply
open file, read or write... close.

But that is a different story

@Bill Glass : Here is a rewrite with a loop() cycling edits through the EEPROM on a T_4.1, no indications of failure. Ran about 8 variations evolving code to this point.

This uses the provided CLASS code in same INO file. If this runs on your T_4.0 it suggests the problem is elsewhere in the larger code.
> If it fails as @KurtE suggests: Add debug and error checks in Library to determine how/where that EEPROM code there fails.

Output of Final code editing all 6 strings first char and repeating 'A' to 'Y'. A power cycle and repeat ran the same and showed proper retention:

@Bill Glass : Here is a rewrite with a loop() cycling edits through the EEPROM on a T_4.1, no indications of failure. Ran about 8 variations evolving code to this point.
This uses the provided CLASS code in same INO file. If this runs on your T_4.0 it suggests the problem is elsewhere in the larger code.

Didn't try your code but modified my library example code below. It fails at iteration 79 as you can see in my print output below. Maybe you could check it in your Teens4.1? Thanx

Code:

#include <StringsToint_EEPROM.h>
#define TABLESIZ 6
StringsTointEEPROM inteeprom; //internal Arduino EEPROM Library for storing and retreiving c-strings

char eaudgc[10]="25";
char eaucm[10]="15";
char eautime[10]="(05:30)";
char airdgc[10]="18";
char airhum[10]="33";
char airtime[10]="(06:30)";
char *tableadr[]={eaudgc,eaucm,eautime,airdgc,airhum,airtime};
unsigned long int millistart;
unsigned long milliduration;


// STRUCTURE OF A STORED STRING
//-----------------------------
// sync (0xaa)
// nchar(0..255)
// char[0]
// char[1]
//  ..
// char[nchar-1]
// 0xff (end of latest string)
//-----------------------------


void setup() {
  int i,iter,nbytes=0;
  Serial.begin(115200);
  delay(1000);
  //inteeprom.format_eeprom(); //needs to be formatted once
  if (inteeprom.begin()==0) Serial.println("begin() ERROR, Format the EEPROM");
  for (i=0;i<TABLESIZ;i++) nbytes+=(strlen(tableadr[i]));
  millistart=millis();
  inteeprom.save_nstrings_to_eeprom(TABLESIZ,tableadr);
  milliduration=millis()-millistart;
  Serial.print("execution time for save_nstrings_to_eeprom() is ");
  Serial.print((float)milliduration/(float)nbytes);
  Serial.println("ms per byte");
  Serial.println("latest 6 strings read from EEPROM");
  millistart=millis();
  if (inteeprom.get_nstrings_from_eeprom(TABLESIZ,tableadr)==0) Serial.println("EEPROM is MT"); //read string
  milliduration=millis()-millistart;
  Serial.println(eaudgc);
  Serial.println(eaucm);
  Serial.println(eautime);
  Serial.println(airdgc);
  Serial.println(airhum);
  Serial.println(airtime);
  Serial.print("total execution time for get_nstrings_from_eeprom() is ");
  Serial.print(milliduration);
  Serial.println("ms");
  inteeprom.save_nstrings_to_eeprom(TABLESIZ,tableadr);
  for (iter=0;iter<100;iter++)
  {
    inteeprom.get_nstrings_from_eeprom(TABLESIZ,tableadr);
    Serial.print("iter: ");
    Serial.print(iter);
    Serial.print(" eaudgc: ");
    Serial.println(eaudgc);
    delay(1000);
    if (strcmp(eaudgc,"25")==0) strcpy(eaudgc,"1"); else strcpy(eaudgc,"25"); //modify 1st string and test reliability
    inteeprom.save_nstrings_to_eeprom(TABLESIZ,tableadr);
  }
}

void loop() {
  // put your main code here, to run repeatedly:

I tried just now, but I don't have the StringsToint_EEPROM.h file. Was this posted earlier? I see what looks like an old version on msg #19. I'm guessing an updated StringsToint_EEPROM.cpp would also be needed?

I'll try running your code here on a Teensy 4.1, but only if you post all the needed code in the same message and the way to copy it into Arduino is clear. Sorry, I just don't have the time to read through 34 prior messages to fine pieces of the needed code, or try guesswork to reproduce the issue. Please provide everything in the same message and leave nothing about how to run it to guesswork or chance.

No problem here on T_4.1 using code below with 100 iteration updates.

Try this code there and see what shows.

Then power cycled and it ran again without error showing even the last update to "W" worked to save and showed on power on restart: W06:30):W5:W5:W05:30):W8:W3

I powered up a Teensy 4.0 and it also worked the same - perfectly well.

Code:

Here is the SKETCH as I have it in its entirety with the CLASS code included: [ATTACH]28916._xfImport[/ATTACH]

Either your T_4.0 Flash is worn out, or elsewhere in the code there it is interfering with proper function. Running this code above should help answer that.

Here are the results from first run with EMPTY FLASH - through 100 and then power Off and On restart that worked:

I tried just now, but I don't have the StringsToint_EEPROM.h file. Was this posted earlier? I see what looks like an old version on msg #19. I'm guessing an updated StringsToint_EEPROM.cpp would also be needed?

I'll try running your code here on a Teensy 4.1, but only if you post all the needed code in the same message and the way to copy it into Arduino is clear. Sorry, I just don't have the time to read through 34 prior messages to fine pieces of the needed code, or try guesswork to reproduce the issue. Please provide everything in the same message and leave nothing about how to run it to guesswork or chance.

@Paul see p#37 for single source solution. Original code 'Header for CLASS and INO" was in a single #CODE# block.

I sorted that out and have evolved the example use of the CLASS func()'s to work on both a T_4.0 and T_4.1 as far as that example code provided allowed.

I ran it twice, first after uploading, then again by power cycling.

This is what it printed to the serial monitor. Is this the correct result?

I ran it twice, first after uploading, then again by power cycling.

This is what it printed to the serial monitor. Is this the correct result?

Code:

/tmp/arduino_modified_sketch_972819/sketch_jul12a.ino Jul 12 2022 16:39:44 latest 6 strings read from EEPROM W5:W5:W05:30):W8:W3:W06:30) latest 6 strings read from EEPROM: 1:: A5:A5:A05:30):A8:A3:A06:30) ... latest 6 strings read from EEPROM: 100:: V5:V5:V05:30):V8:V3:V06:30) EEPROM Updated 100 times COMPLETE.

That is the result I expect.

It cycles EEPROM updates 100 times {changes,writes,reads}, each time changing the first letter of all 6 stored strings.

In each print the first character indexes through A-Z, and the remainder of the strings are present as expected.

Original post suggested it failed after six update cycles, then most recently posted it failed after 79 iterations, so ran to 100

Started a 2us interval timer toggling LED every 500,000 - ran the loop to 1,000 every 100ms and completed fine.

And the 3-4 times rebuilding with those edits to prior code. Nothing odd or wrong showed with that.

I tried just now, but I don't have the StringsToint_EEPROM.h file. Was this posted earlier? I see what looks like an old version on msg #19. I'm guessing an updated StringsToint_EEPROM.cpp would also be needed?

I'll try running your code here on a Teensy 4.1, but only if you post all the needed code in the same message and the way to copy it into Arduino is clear. Sorry, I just don't have the time to read through 34 prior messages to fine pieces of the needed code, or try guesswork to reproduce the issue. Please provide everything in the same message and leave nothing about how to run it to guesswork or chance.

Spent a little time playing with this code to better reproduce the problem. Here is a single piece of code which can be copied into Arduino. It first wipes the EEPROM's storage area so the result doesn't depend on prior stored data (and you don't need to wait for the slow 15 sec button press restore process to start with a clean slate). I increased to 500 iterations and reduced the delay so it runs quickly. Here's the code to copy into Arduino:

It consistently gives unusual results on iterations 121, 270, 493 when I run it here on Teensy 4.1.

iter: 121 eaudgc: (06:30)

iter: 270 eaudgc: 33

iter: 493 eaudgc: 18

I also ran this on Arduino Uno. It gives only 25 and 1 output.

Looks there is some sort of subtle software bug here. Might be in Teensy's core library, might be in this code. Still haven't dug into the problem much yet.... mainly just focused so far on how to better reproduce it.

Hello Paul

The test code is for debugging my Teensy4.0. I developed the library which works fine for my Nano remote sensor monitor using an LCD 16x2. I wanted to save current sensor measurements in EEPROM in case of loss of power. I was tired of using this type of display so I bought a tft display run by a Teensy. I was getting inconsistent display values when I activated the "EEPROM" so I made this test program hoping someone could understand why. My library stores blocks of strings on the EEPROM by appending the most recent block at higher addresses in a circular mode. Recovering an EEPROM block is done at the most recent address. All to do some wear leveling of the "EEPROM" access. The test code just recovers a block of 6 strings, modifies the first value between 1 or 25, then restores to EEPROM. Again, the test code works fine for the Nano but not the Teensy. Voila, that's about all I can say for now.

Oops sorry I am not Paul,

Hope you don't mind one last interruption here...

Paul,

I hacked up your test case here to use a slightly updated KISS save of the strings. Simply put:
I simply store the 6 strings, each one starting at EEPROM index 1, 11, 21, 31, 41, 51

I also updated the test program, to in the loop read in the strings to different memory locations and compare the strings and only print string strings if they don't match...
I also print the elapsedMicros for each iteration through the loop. I also keep a count of errors.
And at the end print out all of the strings and count of errors...

Code:

Wiping EEPROM...............
execution time for save_nstrings_to_eeprom() is 0.00ms per byte
latest 6 strings read from EEPROM

iter: 2 em: 33
iter: 3 em: 26
iter: 4 em: 33
iter: 5 em: 26

iter: 4992 em: 23
iter: 4993 em: 20
iter: 4994 em: 24
iter: 4995 em: 20
iter: 4996 em: 24
iter: 4997 em: 20
iter: 4998 em: 24
iter: 4999 em: 20

*** End of run ***
Count of errors: 0
Strings:  0:1 25 1:15 15 2:(05:30) (05:30) 3:18 18 4:33 33 5:(06:30) (06:30)

Wear leveling is an interesting thing that may or may not work as expected. My run here, is maybe slightly bogus in that, really each run the only thing that changes is the three bytes associated with; the one field alternating between 1 and 25. All of the other writes will see that the current value is the same and as such nothing needs to be done.

So not really sure in your case how many bytes actually change from sample to sample? for example the (06:30) string what changes? only the 06? and with that for many of the hours only the 6? In that case only that one EEPROM value would change.

And if I really wanted to minimize EEPROM wear by usage, I would probably not save as strings... For example how many of those fields could be encoded as one byte each...

I fully understand that since it works well on an 8 bit AVR processor that has physical 1024 byte EEPROM, it should work here on the Teensy. However in the Teensy case, your optimizations for the AVR are working counter to how the EEPROM emulation code is implement on the Teensy and is instead of being an optimization it is a worst case scenario stress test on the Teensy. Which is why Paul may want to debug it and see if he can uncover what the issue is and hopefully fix it. But it still will mostly likely continue to be Flash wear maximizer instead of a minimizer.

If anyone is interested in the version I tested, it is below, if not no big deal. But I am done...

Kurt

Something strange worth taking a more detailed look at . . .

I decided to take a different look at this problem. I added some debug spits to detail all of the EEPROM addresses & the data READ/WRTTEN from/to those addresses. Something strange popped out as a result: it appears that the operations constraining the EEPROM address to the range 0-1023 are not always resulting in proper values (instead of the expected EEPROM address value of "1023", it is sometimes resulting in a EEPROM address of "65535"), which may or may not cause a problem (as Paul found, it is consistently a problem for passes 121, 270, & 493, but not for others, such as 29, 60, 90, 158, 195, 232, 269, 307, 344, 381, 418, & 456).

To demonstrate this problem, make sure that line 39 reads "#undef PERTINENT_DEBUG", which will print all of the debug spits. Scroll thru & observe the pass numbers listed above . . . in all cases (those that have a deleterious effect & those that don't seem to bother anything) you'll see that the EEPROM address reported is "65535". Then, to make it easier to debug, change line 39 to read "#define PERTINENT_DEBUG" & the unaffected READs & WRITEs will be suppressed.

Here's the code that I used (with line 39 initially setup for full debug):

Code:

#include <EEPROM.h>

#define DO_WRITE true

Ok you all got me curious so decided to run a 3 basic sketches that I pulled off the web. Note: I am running on a T4.0

SUmmary: Sketches 1 and 2 work but sketch 3 fail on writing negative ints to eeprom. Not sure why though.

Sketch 1: Writing strings to eeprom (add a 5000 count loop just to see if any errors showed:

Code:

//https://roboticsbackend.com/arduino-write-string-in-eeprom
[COLOR="#FF0000"][B]/*Running this sketch with 5000 writes/reads:
No errors seen
*/[/B][/COLOR]

#include <EEPROM.h>

int writeStringToEEPROM(int addrOffset, const String &strToWrite)
{
  byte len = strToWrite.length();
  EEPROM.write(addrOffset, len);
  for (int i = 0; i < len; i++)
  {
    EEPROM.write(addrOffset + 1 + i, strToWrite[i]);
  }
  return addrOffset + 1 + len;
}
int readStringFromEEPROM(int addrOffset, String *strToRead)
{
  int newStrLen = EEPROM.read(addrOffset);
  char data[newStrLen + 1];
  for (int i = 0; i < newStrLen; i++)
  {
    data[i] = EEPROM.read(addrOffset + 1 + i);
  }
  data[newStrLen] = '\0'; // !!! NOTE !!! Remove the space between the slash "/" and "0" (I've added a space because otherwise there is a display bug)
  *strToRead = String(data);
  return addrOffset + 1 + newStrLen;
}

int icount = 0;
void setup() {
  Serial.begin(9600);
  int eepromOffset = 0;
  // Writing
  String str1 = "Today's tutorial:";
  String str2 = "Save String to EEPROM.";
  String str3 = "Thanks for reading!";
  int str1AddrOffset = writeStringToEEPROM(eepromOffset, str1);
  int str2AddrOffset = writeStringToEEPROM(str1AddrOffset, str2);
  writeStringToEEPROM(str2AddrOffset, str3);
  // Reading
  String newStr1;
  String newStr2;
  String newStr3;

  for(int i = 0; i < 5000; i++) {
      icount += 1;
    int newStr1AddrOffset = readStringFromEEPROM(eepromOffset, &newStr1);
    int newStr2AddrOffset = readStringFromEEPROM(newStr1AddrOffset, &newStr2);
    readStringFromEEPROM(newStr2AddrOffset, &newStr3);
    
    Serial.print(icount); Serial.print(": ");
    if(strcmp(str1.c_str(), newStr1.c_str()) != 0) { Serial.print(newStr1); Serial.print(" : ");  }

Now on to something more interesting with the eeprom

KurtE said:
If anyone is interested in the version I tested, it is below, if not no big deal. But I am done...

Oops I lied...
I decided to update the sketch from previous post, to for one thing, dump the contents of the EEPROM after the run

This uses my MemoryHexDump library which is up in on my Github ...
I also on each iteration now, copy the 15 sectors of EEPROM data into big buffer in DMAMEM
And now if I get an error I will dump both the previous contents before the run and contents after that iteration.

Hopefully will give clues on what went wrong...
I also made the code #ifdef to allow my KISS version and the EEPROM stress version...

Dump output from KISS version:

Code:

*** End of run ***
Count of errors: 0
Strings:  0:1 25 1:15 15 2:(05:30) (05:30) 3:18 18 4:33 33 5:(06:30) (06:30)
