QTIMER INTERRUPTS from COMPARATORS

With QTimers, there are two "Status and Control" registers - for example, TMR3_SCTRL1 and TMR3_CSCTRL1. The first is the Status/Control for the timer as a whole. The second is the Status/Control for comparators.

Interestingly, BOTH of these have "interrupt enable" bits for the comparators. Previously, I had set and cleared these bits in both registers when desiring an ISR.

But today I discovered that you do not have to use the IE bit in the SCTRL1 register in order to fire an ISR. It is sufficient to set one of the IE bits in the CSCTRL1 register. This means only one bit (flag) needs to be reset (to zero) within the ISR for respectable/reliable interrupt operation.

The code is:
Code: 
  unsigned freq = 15000000; //15MHz or any other.. works up to F_BUS_ACTUAL / 2 = 75MHz (without overclocked F_BUS)
  TMR3_CMPLD10 = F_BUS_ACTUAL / 2 / freq - 1;

Edit: Verified with my scope. It show a few Hz off - might be an issue with the scope.

Interesting - have to go pull out my scope now as check. Went back to original sketch as test. If I use the form you posted I get double the freq that I specify when using the gpt clk/interrupt. Here is the sketch if you want to check:
Code: 
// GPT1 counter like FreqCount
// external pin is 14 GPIO_AD_B1_02 ALT8  (Frontside - A0)
// test with  PWM pin 13 jumpered to 14

// FreqCount API
static inline void counter_init(void)
{
  CCM_CCGR0 |= CCM_CCGR0_GPT2_BUS(CCM_CCGR_ON) ;  // enable GPT1 module
  //CCM_CCGR0 |= CCM_CCGR0_GPT2_SERIAL(CCM_CCGR_ON) ;
  GPT2_CR = 0;
  GPT2_SR = 0x3F; // clear all prior status
  GPT2_CR =  GPT_CR_CLKSRC(3);// | GPT_CR_FRR ;// 3 external clock
  //*(portConfigRegister(14)) = 8;  // ALT 8
  //CORE_PIN14_CONFIG = 8; 
  IOMUXC_SW_MUX_CTL_PAD_GPIO_AD_B1_02 = 0x08;
  IOMUXC_GPT2_IPP_IND_CLKIN_SELECT_INPUT = 0x01;
}

static inline void counter_start(void)
{
  GPT2_CR |= GPT_CR_EN; // enable
}

static inline void counter_shutdown(void)
{
  GPT2_CR = 0;
}

static inline uint32_t counter_read(void)  // was uint16_t in FreqCount?
{
  return GPT2_CNT;
}

static inline uint8_t counter_overflow(void)
{
  return GPT2_SR & GPT_SR_ROV;
}

static inline void counter_overflow_reset(void)
{
  GPT2_SR |= GPT_SR_ROV;
}

volatile uint32_t count_ready, count_output, count_prev;
void tmr_callback() {
  uint32_t count = counter_read();

  //track rollover ?
  count_output = count - count_prev;
  count_prev = count;
  count_ready = 1;
}

IntervalTimer it1;

void setup() {
  Serial.begin(9600);
  while (!Serial);
  delay(2000);
  pinMode(13, OUTPUT);              //pin 13 as digital output

  
  //enable clocks for QTIMER3
  CCM_CCGR6 |= 0xC0000000;                    //enable clocks to CG15 of CGR6 for QT3

  //configure QTIMER1 Timer0 for test. Period = 65,536 = 436.9 uS (times 2) - rollover

  TMR3_CNTR0 = 0;
  TMR3_LOAD0 = 0;
  //TMR3_COMP10 = 10000 -1;              // 6.7nS per clock = 66.7uS for 10,000 clocks on each half cycle
  //TMR3_CMPLD10 = 10000 -1;
  unsigned freq = 4000000;
  Serial.println(F_BUS_ACTUAL/2/freq-1);
  TMR3_CMPLD10 = F_BUS_ACTUAL /2/ freq - 1;
  TMR3_CSCTRL0 = 0b0000000001000001;  //Compare1 interrupt enable
  TMR3_CTRL0 = 0b0011000000100011;  // 001(Count rising edges Primary Source),1000(IP Bus Clock),00 (Secondart Source), 
                                    // 0(Count Once),1(Count up to Compare),0(Count Up),0(Co Channel Init),011(Toggle OFLAG on Compare)
  
  //configure Teensy pin Compare output
  IOMUXC_SW_MUX_CTL_PAD_GPIO_AD_B1_00 = 1;    // QT3 Timer0 is now on pin 19
  
  //enable GPT1 interrupt within NVIC table
  attachInterruptVector(IRQ_QTIMER3, QT3_isr);  //declare which routine performs the ISR function
  NVIC_ENABLE_IRQ(IRQ_QTIMER3);

  counter_init();
  it1.begin(tmr_callback, 1000000);  // us
  counter_start();

}

void QT3_isr(void) {
  digitalWriteFast(13, 1);
  TMR3_SCTRL0 = 0b0100000000000001;
  TMR3_CSCTRL0 = 0b0000000001000001;
  digitalWriteFast(13, 0);
  asm volatile("dsb");
}


void loop() {
  if (count_ready) {
    Serial.printf("Freq Count = %d\n",count_output);
    count_ready = 0;
  }
}

If I use analogWriteFrequency seems like I can get readings up to 15Mhz I think

Can probably do either: But if multiple ones on same SPI buss, you can obviously only do one at at a time using DMA...

My ST7735_t3 branch/fork updated: https://github.com/KurtE/ST7735_t3/tree/FB_Asynch
I have simple test program currently updating two displays I believe at same time:View attachment 17055

Which is going through lots of the Teensyview demo screens...
...
I probably want to test this out a little on at least T3.6 to see that it works before I then merge it into my other fork/branch with a current PR into the master...

I just got two ST7789 240x240's today - will they work with this current code?

If there is a working example, a pointer would be great and I can hook them up. These are the ones with software select missing a pin IIRC?

@TelephoneBill - Been using recent QTimer example - is there an example like that showing the IE bits as you have found them to work?

Tried LTO optimization and compile fails. Simple sketch problem is in setup() with call to ultoa():
Code: 
void setup() {
	Serial.begin(115200);
	while (!Serial && millis() < 4000 );
	Serial.println("\n" __FILE__ " " __DATE__ " " __TIME__);
	uint32_t foo = 1234567;
	char buf[24];
	ultoa( foo, buf, 10 );
	Serial.print( ultoa( foo, buf, 10 ) );
	pinMode( 13, OUTPUT );
}
uint32_t cnt = 0;
void loop() {
	cnt++;
	digitalWriteFast( 13, cnt % 2 );
	delay(500);
}

Step ONE:: Compile/Upload default FASTER and upload to see it work to a T4B2.
Step TWO:: results in this error ( hand coded the (used) pull request noted before in startup.c and it does not affect this )::

Step FOUR: Do Verify Build ( not Upload)
Step FIVE: Press T4B2 button - fails to program - Red Bootloader LED stays ON, until an Upload is selected - even if a second T4 is plugged in place of the first T4:

Anyway, we have to live with the old 5.4, so we should try to find a workaround.

No, did the one quick check with gDrive ARM6 - noted it failed to find the exe to compile - mjs513 suggested yet another hack just replacing the ARM not adding ARM6 path - seemed since toolchain wasn't likely to be changing at this late date - that it wasn't worth messing build up.

So as you said either we need to get workarounds done - or find enough things broken to justify making a toolchain update.

Of course these possibly point to issues with segmentation or other 1062 mem .ld choices - which means they could follow the toolchain - or perhaps resolve out in an unplanned way.

So far I have not had much luck with these types of displays that do not have a CS pin.

What I have read up on the web is some/all of them may require +5v to their VIN (looks like a VR on them).

Some had luck editing Adafruit_st7735/89 library, although it looks like some of the stuff may be built in now...

But the instructions were to set CS to -1 so that it was not used... I tried instead just using some random CS pin... Then instead of SPI_MODE0, some say for these boards you need SPI_MODE2 and others say SPI_MODE3. I was experimenting with that with my previous boards, but I think they are all DOA.

The Init code on Adafruit library allowed you to pass in a SPI_MODE to the ST7789::init method. So my current version allows it as well and defaults to SPI_MODE0.
But in theory you should be able to do: tft.init(240,240, SPI_MODE3);

And or SPI MODE 2... But non of them worked for me...

When I tried the last one I got from EBAY - when I tried starting it up, it almost looked like a tear in the display when it was powered up...

I have two other ST7789 displays: One from Adafruit, which arrived yesterday... Have not tried it yet.
And one from Amazon (https://smile.amazon.com/gp/product/B07MH93747/) which has CS pin and works.

I may be trying these st7789's on ESP32 - looking that way this Adafruit FORK has this line:
/Arduino-ST7789-Library/blob/master/examples/graphicstest/ESP32_Watch_graphicstest.ino#L35
> noted as :: This is a library for ESP8266 and the ST7789 IPS SPI display.
//Arduino_ST7789 tft = Arduino_ST7789(TFT_DC, TFT_RST); //for display without CS pin
Click to expand...

I wonder if they have captured any of the machinations needed to operate like the KeDei?
 
@defragster -
For what it is worth, this is the same constructor as if you, did: /Arduino_ST7789 tft = Arduino_ST7789(TFT_DC, TFT_RST, -1);

As -1 is default value in this constructor...

And then it leads to an interesting bug:
Code: 
 pinMode(_dc, OUTPUT);
  if(_cs) {
	  pinMode(_cs, OUTPUT);
  }

#if defined(USE_FAST_IO)
  dcport    = portOutputRegister(digitalPinToPort(_dc));
  dcpinmask = digitalPinToBitMask(_dc);
  if(_cs) {
	csport    = portOutputRegister(digitalPinToPort(_cs));
	cspinmask = digitalPinToBitMask(_cs);
  }
That is no CS is set to int8_t -1... But they test for 0 to say don't do CS, where 0 is a valid IO pin...
And it looks like they default to SPI_MODE2: mySPISettings = SPISettings(24000000, MSBFIRST, SPI_MODE2);

Indeed as noted - suggests they put in the comment but may not have tried the code much ? As they also have this for _LOW and _HIGH:
Code: 
inline void Arduino_ST7789::CS_LOW(void) {
	if(_cs) {

though maybe other elements of that code might be useful versus the LA decode you and mjs513 have been doing for KeDei and rPi hacking:
static const uint8_t PROGMEM
cmd_240x240[] = { // Initialization commands for 7789 screens
Click to expand...

But maybe that is in other sources and working.

problem in that code could be, without CS pin, that bit in the CMD word as needed (?) - based on quick reading of KeDei comments - to get software CMD bit in controller to activate the device? And then on common bus it could only work for one display

Nice price is why I ordered a pair - only to have KurtE note the missing CS pin - so that needs resolved. They did it on the rPi KeDei 480x320 display as it seems to work.
Click to expand...

Well it might be possible to solder in a CS pin, since the 12 pin connector looks like it has wire connectors to the pins and resistors/capacitors.

But I wonder for multiple displays whether using a transistor between SCLK and MISO and the pins would allow turning one off and one.

I've seen this in my own program, too.

Fixed - Bug in the drawLine function that was not detecting we were in frame buffer mode and it was starting an SPI transaction and at end was sending NULL char, plus ending transaction.
Which in the case of continuous updates screws things up.

@defragster -
For what it is worth, this is the same constructor as if you, did: /Arduino_ST7789 tft = Arduino_ST7789(TFT_DC, TFT_RST, -1);

As -1 is default value in this constructor...

And then it leads to an interesting bug:
Code: 
 pinMode(_dc, OUTPUT);
  if(_cs) {
	  pinMode(_cs, OUTPUT);
  }

#if defined(USE_FAST_IO)
  dcport    = portOutputRegister(digitalPinToPort(_dc));
  dcpinmask = digitalPinToBitMask(_dc);
  if(_cs) {
	csport    = portOutputRegister(digitalPinToPort(_cs));
	cspinmask = digitalPinToBitMask(_cs);
  }
That is no CS is set to int8_t -1... But they test for 0 to say don't do CS, where 0 is a valid IO pin...
And it looks like they default to SPI_MODE2: mySPISettings = SPISettings(24000000, MSBFIRST, SPI_MODE2);

Ok - wasn't planning on this but you caught me at a weak moment. So for $5 each I went ahead and ordered a pair. I took a quick look and found this that looks like its for the same display: https://github.com/devbis/st7789_mpy
 
FreqCount - FreqMeasure Libs

Resolved the issue I think I was having - I put QT3 on one T4 and ran lib examples on the other teensy. That seemed to work better. But.... Looks like I can get a max of 10Mhz with FreqCount and 5Mhz with FreqMeasure. Seems funny.

Hmm, maybe you are lucky to get that. On the T4 the GPT is clocked at 24mhz, and ref 51.3.1 says "input frequency should be less than 1/4 of frequency of the peripheral clock (ipg_clk)". Now i do get my peripheral and ipg_clk confused... You could change source clock for GPT to 150mhz, but that changes source clock for PIT (and breaks interval timer etc.). ? Or since we're using external clock for GPT in this case, maybe the 24mhz doesn't apply ??

I don't think that applies. Looking at the GPT clock figure in the GPT chapter the Input Clock is selectable - 24Mhz or Input Clock. Just don't know what the reason cant get more.
 
QTIMER INTERRUPTS from COMPARATORS

@TelephoneBill - Been using recent QTimer example - is there an example like that showing the IE bits as you have found them to work?
Click to expand...
@defragster - This three phase example illustrates the point. It is derived from my previous "alternating compare" example, which is why Compare1 and Compare2 are both being used.

I have not set Bit 14 (TCFIE) in SCTRL (page 3130), but have used Bit 7 (TCF2EN) in CSCTRL (page 3133). The ISR is called three times during one 100KHz cycle when each phase reaches its Compare2 value. I'm only needing to clear CSCTRL flags.

Looks to me as if the QTimer interrupts (when enabled and due) are or'ed together before sending to the interrupt mechanism?

Well, the proof may be in the pudding -- since it doesn't want to count above 10mhz.

So I changed the test sketch to not use the interval timer (spin on micros() for a second), and before init'ing GPT2 clock, changed source clock to 150mhz
CCM_CSCMR1 &= ~CCM_CSCMR1_PERCLK_CLK_SEL; // turn off 24mhz mode
and sketch counted properly for PWM running at 15 mhz (which wasn't working in 24mhz mode).
Works @30mhz, and when i PWM @40mhz, it reports 37.5mhz, and 50 MHz PWM reports 50 mhz.

modified sketch
Code: 
// GPT2 counter like FreqCount
// external pin is 14 GPIO_AD_B1_02 ALT8  (Frontside - A0) Serial3 Tx
// test with  PWM pin 11 jumpered to 14

// FreqCount API
static inline void counter_init(void)
{
  CCM_CSCMR1 &= ~CCM_CSCMR1_PERCLK_CLK_SEL; // turn off 24mhz mode
  CCM_CCGR0 |= CCM_CCGR0_GPT2_BUS(CCM_CCGR_ON) ;  // enable GPT1 module
  //CCM_CCGR0 |= CCM_CCGR0_GPT2_SERIAL(CCM_CCGR_ON) ;
  GPT2_CR = 0;
  GPT2_SR = 0x3F; // clear all prior status
  GPT2_CR =  GPT_CR_CLKSRC(3);// | GPT_CR_FRR ;// 3 external clock
  //*(portConfigRegister(14)) = 8;  // ALT 1
  //CORE_PIN14_CONFIG = 8;
  IOMUXC_SW_MUX_CTL_PAD_GPIO_AD_B1_02 = 8;
  IOMUXC_GPT2_IPP_IND_CLKIN_SELECT_INPUT = 1;
}

static inline void counter_start(void)
{
  GPT2_CR |= GPT_CR_EN; // enable
}

static inline void counter_shutdown(void)
{
  GPT2_CR = 0;
}

static inline uint32_t counter_read(void)  // was uint16_t in FreqCount?
{
  return GPT2_CNT;
}

static inline uint8_t counter_overflow(void)
{
  return GPT2_SR & GPT_SR_ROV;
}

static inline void counter_overflow_reset(void)
{
  GPT2_SR |= GPT_SR_ROV;
}

volatile uint32_t count_ready, count_output, count_prev;
void tmr_callback() {
  uint32_t count = counter_read();

  //track rollover ?
  count_output = count - count_prev;
  count_prev = count;
  count_ready = 1;
}

//IntervalTimer it1;
uint32_t us;
void setup() {
  Serial.begin(9600);
  while (!Serial);
  delay(2000);
  analogWriteFrequency(11, 40000000);  // test jumper 11 to 14
  analogWrite(11, 128);

  counter_init();
  //it1.begin(tmr_callback, 1000000);  // us
  counter_start();
  us = micros();
}

void loop() {
  if (micros() - us >= 1000000) {
    uint32_t count = counter_read();
    us = micros();
    count_output = count - count_prev;
    count_prev = count;
    Serial.println(count_output);
    // count_ready = 0;
