Is there any code please I have no idea from where I should start.

Hi @KrisKasprzak, could you give me the full code please? Iam very need to like that, I have array in sketch on esp32 and I need to send this array to teensy. any advice please?

How can I send 1D array from esp32 to teensy4.0 ? I have array in sketch of esp32 and I need to sent it to the teensy by Wi-Fi or BLE. Is there a possibility of such a thing and how is it done?

@manitou , what do you mean in this " ESP32 has hardware float, T4 has hardware double and float "

@Frank B, No, is the same I'm just change the microcontrollers

No, I can't, it very big.

Yes, thanks, I was wondering because I have a code that when I use double datasets and run it on Teensy, it gives different results than in ESP32 for the same parameters and dataset.

Does Teensy4.0 deal with double dataset? For this link https://www.pjrc.com/store/teensy41.html says: "Float point math unit, 64 & 32 bits" Does this mean that it only deals with float datasets ?

are you speaking seriously?!!! I know that from the beginning!!! Anyway Thanks! :(

I can not attach file in this form but yes it constant like this :

For example I have 10 txt file in each file 1000 values have the same type.

Ok Frank B, thank you, Can you tell me how can I use " string constant and #include it." because I have many files and this is very difficult to use a constant arrays . because I need to send these arrays to function to make some processing on the values. functionxx(array);

No change! I should use s - to log data x to stop logging d to dump data. to open the datalog file and in this way I cant read my values. if I use just d I get on like in image :

Yes I know and I did that. but I need to read the data in my txt file not the data from s

The same problem I can not read may values in txt file: this is the output : So my txt file didnot read !

Also, I cannot read the file that contains my data. Can you help me solve the code #6? At first it only prints -1, now it prints "error opening datalog". In all cases, I can't read from a file yet :(

If I have data(values) in txt file on my pc , how can I read this file with teensy? I was read from txt file with esp32 easily!

In fact, I'm new in microcontrollers so with esp32 I used SPIFFS and create Data folder and then read the file from it normally. Now I'm trying to do same thing with Teensy and I have no information about that. I run this code and I get on " Error starting PROGRAM FLASH DISK" This is my teensy.

I update on my code, and I can not open the file "error opening datalog.txt" . I just want to read data from a txt file in this array data. "

OK, Now this is my code : I get in the out put just -1 ! this value is not in file, how can update on this simple code? please? #include <LittleFS.h> LittleFS_SPINAND myfs; //Specifies to use an SPI NOR Flash attached to SPI void setup() { // Open serial communications and wait for port...

Thank you very much for the quick answer.. Actually I read this example and now I'm trying to run it on Teensy.. I have a question, please, do I create a folder "Data" inside the sketch folder? In order to read the file from it ? as in ESP32 ?

Hi, Is there any way that I can read a file using the file system in Teensy ? something like using #include "SPIFFS.h" in ESP32 ? any advice please ?

I'm trying to read txt file (has numeric values) line by line. I used SPIFFS with ESP32 and I used this function void readFile(fs::FS &fs, const char * path){ Serial.printf("Reading file: %s\r\n", path); File file = fs.open(path); if(!file || file.isDirectory()){...

I used two types of microcontrollers and they work !! I used with the first one Serial.begin(9600); while (!Serial) { ; // wait for serial port to connect. Needed for native USB port only } and and with the second : Serial.begin(115200); JUST with teensy I have problem!!!!

The same problem "the output in serial monitor is just print "before function " after that the COM be offline and then rebooting and re printing "before function " .... and so on... "

The problem is not with the code because it works correctly with ESP32! but with teensy , after upload the code , the output in serial monitor is just print "before function " after that the COM be offline and then re printing "before function " .... and so on...

After upload the code , the output in serial monitor is just print "before function " after that the COM be offline and then re printing "before function " .... and so on...

This is part of my code : every thing after the function is not printing , Why ?!! I run the same code on esp32 and it work well ! void setup() { Serial.begin(9600); while (!Serial) { ; // wait for serial port to connect. Needed for native USB port only } Serial.println("0")...

Yes, you're right, but I can't share the code because it's too big, but I'm wondering are there any changes that I can make on the code or setting to run it on teensy? why does it work so well on ESP32?

Hi, I am new here and this is the first time that I use Teensy 4.0. I'm working on code and I run this code on ESP32 , this code is working without any problem with esp32 . Now I'm trying to run the same code on teensy 4.0, the problem the USB stay in case of plug in and plug out. and when open...
