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 ...Wed, 01 Apr 2026 05:54:00 GMThttps://forum.arduino.cc/t/watchdog-timer-wdt-prevent-esp32-from-stucking/1308022The best way to answer this is to have you grab your favorite search engine and look for 'WDT RDP32 xxx,' where WDT stands for Watchdog Timer and xxx is the specific unit you have.Fri, 03 Apr 2026 01:48:00 GMThttps://forum.arduino.cc/t/start-a-timer-when-button-is-pressed/856752I 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 ...Mon, 30 Mar 2026 15:43:00 GMThttps://forum.arduino.cc/t/too-many-arguments-to-function-hw-timer-t/1389998too many arguments to function 'hw_timer_t* timerBegin (uint32_t)' 528 | timer = timerBegin (0, 80, true); // Alarm value will be in in us it looks like you are attempting to build code using ESP32 core 3.x which was implemented for ESP32 core 2.x have a look at the ESP32 core V3.x Arduino-ESP32 Timer API also worth looking at is Migration from ESP32 core 2.x to 3.xMon, 30 Mar 2026 07:22:00 GMThttps://forum.arduino.cc/t/how-to-select-a-timer-in-esp32-arduino-api-3-0/1364989Thanks to several real knowledgeable members I'm starting to understand the nuances of esp32 timers. I still has a few question to resolve: In API version 2.0 you selected which 1 of the 4 timers you wanted in "timerBegin(timer#, pre-scaler,count_direction)" now there is only 1 parameter "Frequency". Where do I select the timer number? A second question is what are the allowable frequencies ...Tue, 31 Mar 2026 08:33:00 GMThttps://forum.arduino.cc/t/handling-timer-overflow-interrupts/489152I clear the timer, set it up in Input Capture Mode, set the pre-scaler to ClkIO/1024, and enable Overflow interrupts, as the event I'm timing can take up to 10 seconds, which means the timer may overflow twice. I maintain a software count, in a uint32_t that is increment by 65536 every time an overflow occurs.Mon, 30 Mar 2026 06:18:00 GMThttps://forum.arduino.cc/t/solved-timer-h/517548As you understand I need a hardware timer (counting clock ticks). Millis () makes demanding to ckeck if "old value" is smaller than millis () value (normal run from start until rollover) or greater (1st time after rollover) before any compare.Thu, 02 Apr 2026 00:23:00 GMThttps://forum.arduino.cc/t/programmable-switch-timer/1272709I have beginner skills on arduino, and I kind of jumped the gun into a project for school, to build a programmable switch timer, it has 4 buttons The switch is to be able to program on and off times of a bulb, it should be able to set 2 programs daily for each day of the week(i.e. i can manually program 2 on/off times for each day Monday through sunday).This also implies that date, time are ...Thu, 02 Apr 2026 13:02:00 GMThttps://forum.arduino.cc/t/six-digit-seven-segment-display-countdown-timer/1169656Namely, a countdown timer with six seven segment displays that shows the remaining months, days, and hours set by the user via push-buttons. The actual countdown would then be controlled by an RTC module (I read somewhere that the Arduino's internal timer is not accurate for extended time periods).Thu, 02 Apr 2026 08:59:00 GMThttps://forum.arduino.cc/t/esp32-timer-interrupt/1270199Hi Folks, I am using Esp32 Dev Module to develop the timer interrupt code .but when I am using timerBegin () function I am getting errors like that: timerBegin () function can accept only one argument.Please help me out t…Thu, 02 Apr 2026 19:43:00 GMT
