Hi, Is there any periodic timer interrupt example for Portenta? I tried many libraries claiming it is working but it doesn't compile. Thanks

I've used the mbed os tickers with some sucess. #include "mbed.h" using namespace mbed; Ticker t; uint8_t t0 = 0; void setVar() { //digitalWrite(LEDB,LOW); if (t0 == 1) { t0 = 0; } else { t0 = 1; } } void setup() { Serial.begin(115200); t.attach(&setVar, 0.2); // .attach(&f…

Thank you for your response, This is a soft timer which I was not looking for. I was looking for more like a hardware timer like Timer1 in Arduino. I was able to find a good library for making concurrent threading that was running on top of mbed OS and made an example for reference : /** * Blinki…

Hi wbadry, Do you know if the Thread library still works? I tried to use it to perform a timer interrupt but it gave me an error which is the following "exit status 1 Error compiling for Arduino Portenta H7 (M7 core) board. " Thanks.

Yes, it is broken now. I am looking for an alternative

Thank you for your response, I've also been looking for an alternative, but so far nothing has worked.

Hi @wbadry I have used the registers directly to access the hardware timers. /** * This program blinks built in Blue led of Portenta H7 at a frequency of ~1Hz using Hardware Timer 3. * This program uses HSI clock as the source (can also be replaced with HSE, CSI, PLL1 clocks) * NOTE: This pro…
