- 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
- 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
- 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
- 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
- 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
- [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
- Configuring Timer1 Overflow Interrupts - Arduino Forum
Hi all - been trying to get some Timer1-related stuff working for my arduino project (just got into this about a week ago) but I'm having a little trouble understanding a few things about timer1 Here's the ideal setup: I want to use Timer1 as a global timer that is always running, that allows me to synchronize when certain events happen in the system Is it possible to slow down the speed of
- Timer circuit with three relays and 8hours interval operation
I very recently have started tinkering around and am unaware of most of the technicalities, I have three 5v relays which I want to operate in 8 hours interval daily which means any two out of the three would be active at any point of time in a day For clear understanding; naming relays as Relay1, Relay2 and Relay3; now, beginning at 00:00:00 Relay1 and Relay2 should be HIGH for eight hours i
