I maintain a software count, in a uint32_t that is increment by 65536 every time an overflow occurs.Wed, 15 Apr 2026 06:20:00 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, 23 Apr 2026 01:46:00 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 ...Fri, 17 Apr 2026 05:49:00 GMThttps://forum.arduino.cc/t/programming-timer-interruption/1350441I'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 ...Tue, 14 Apr 2026 08:30:00 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 ...Mon, 20 Apr 2026 13:31:00 GMThttps://forum.arduino.cc/t/mega-timers/672091Where will I get information about the timer output to Mega pins assignment? like the attachment for UNO.Mon, 20 Apr 2026 07:04:00 GMThttps://forum.arduino.cc/t/countdown-timer/1440331countdown timer that will count down from 2 minutes then when time is up it will continue into minus count (overrun) until the reset is triggered back to the start command.Thu, 23 Apr 2026 11:19:00 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…Tue, 21 Apr 2026 00:08:00 GMT
