Programming timer interruption - Arduino Forum I'm posting here a simple project to create an interrupt timer on an ESP32 board for version 3 1 1 by Esspressif Systems I had difficulties to find updated information to make this code, I hope it can be useful to someone ! This code creates an interrupt every 100ms and counts the number of interrupts There is the code : #include "esp32-hal-timer h" const int ledPin = 2; pin of the LED
FspTimer: using AGT timer issues - UNO R4 Minima - Arduino Forum Note: servo_timer get_period_raw () returned a period of 960000 Which does not make sense, as I am pretty sure this is a 16 bit counter Wonder maybe it did not like to do a period that long So tried changing to 1500 Raw Period: 71999 Tried 750 -> 35999 Thoughts? Are there known issues with FSP and AGT? Thanks Kurt 1 Like KurtE September 2
Start a timer when button is pressed - Arduino Forum I am creating a timer for a race I have a photosensor that has a laser pointed to so when someone crosses the finish, it trips the sensor, and the system logs the racer's time I am using millis() to time the race, but I need the timer to start when I push the button I have tried using edge detection to start the timer, but the timer starts when the program starts, not when the program
Questions about FspTimer. h - UNO R4 Minima - Arduino Forum Hi all , after spending every spare moment over the last few weeks reading the forum and googling , I keep going around in circles getting no where So I have joined the forum in the hope that I can get help I am not a total newbie to programming or Arduinos but I am still very unfamiliar I managed to get Timers working on R3 using direct timer registers and that all made sense to me but

1mS Timer - Programming - Arduino Forum I changed the code to set the timer in CTC Mode, but still get 1004uS every once in a while Every once in a while, your timer will expire while the AVR is off in un-interruptable code (notably the timer0 interrupt or a serial interrupt), leading to some delay before the ISR is serviced
