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
[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
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
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
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
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
Search (While You Type) in a ComboBox - Experts Exchange A Timer Form Perhaps this would warrant a distinct article Each form has a timer event, triggered when the timer interval drops to zero If a timer is needed, it is therefore possible to create a tiny form for the sole purpose of counting down some interval, and to trap its timer event This is of course a bit of an overkill — opening an entire form just for a timer — but since Visual
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
