- 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
- 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
- 7 Segment Count Down Timer Project - Arduino Forum
The timer would stop when the stop button is pressed and after the time is stopped, pressing the reset button would reset the time to 02:00 mins to wait for the start button to be pressed again
- 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
- Timer use with FspTimer - UNO R4 WiFi - Arduino Forum
Hello together, here I'm new but I have some experience with HC08 µC programming in C and Assembler I try to use an Arduino Uno R4 Wifi to capture an input signal with GPT321 Unfortunately I didn't found an example for this and therefore I started to lern something about the timers and use the code from Phil Schatzmann without any changes As far as I understand this code demonstrates a
