The 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
- 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
- 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
- [Solved] Timer. h - Programming - Arduino Forum
As 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
- Programmable switch timer - General Guidance - Arduino Forum
I 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

- FspTimer: using AGT timer issues - UNO R4 Minima - Arduino Forum
@ptillisch and others, not sure if best to ask here, or up on Github issues? As I mentioned in the Servo library Issue, plus forum post, I have not handled the case where the FsPTimer ends up trying to use an AGT timer I thought I would try to make it work If it works, will also update my Charlieplex code as well So not sure best place But as this is a stand alone issue, decided to ask on
- Handling Timer Overflow Interrupts - Arduino Forum
I 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
