ARDUINO TIMER INTERRUPT PIN 2 SERIAL

Static void adc_read (void *pvParameters ) Serial.println('The device started, now you can pair it with bluetooth!') Īdc_read, /* Function to implement the task */īl_send, /* Function to implement the task */ SerialBT.begin('ESP32') //Bluetooth device name

PortMUX_TYPE timerMux = portMUX_INITIALIZER_UNLOCKED So it's just the core 0 function somehow not responding to that. So the problem remains, but I just added this info.ĮDIT1: I also noticed the interruptCounter goes up like it's supposed to during these stops. The interval and the pulses between these glitches seem to be irrergular. I tried many things, but I still have no idea how one core affects the other in this code.ĮDIT: After finding the run/stop button on the oscilloscope, I realised that it still mostly toggles at a regular 100us interval, but every after every few toggle it forgets to toggle for a few ms usually.

However, if I open the serial monitor on the port associated with bluetooth, the pin toggles at very random intervals, so the frequency changes all the time. If I delete SerialBT.println('1') function, or use Serial.println('1'), or don't open the bluetooth serial monitor on Arduino IDE, it works fine and I get a nice 5 kHz square signal. On core1 I have a task which sends some gibberish on bluetooth with the SerialBT.println('1') function. In the core0 task I set up a timer interrupt that signals to the task (through the interruptCounter variable) to toggle a pin every 100 us.
