[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.

In need of timer interrupts on Arduino Giga
Hi, I have been searching for days trying to find a library or description of how to set up Timer Interrupts on the Arduino Giga. I have tried many libraries but they seem to not be compatible. Can someone please post instructions of how to create for example a timer interrupt at 100Hz calling an ISR where you enter the ISR with CLI and SEI (as I understand it noInterrupts() and interrupts . . .

Timers on the Arduino Mega 2560
Hi all, I am contemplating a project where I would want to have three independent timer interrupts running simultaneously and want to understand how the Arduino platform uses the timers on the Mega (ATMega 2560-based boards). As I understand, the ATMega 2560 has four 16-bit timers available and two 8-bit ones. Ideally I would like to hijack three of the 16-bit timers. My question is, I know . . .

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 . . .

Unable to get timers to compile on ESP32 nano - Arduino Forum
Regards. Wayne in NH. have a look at this ESP32 code which measures pulse width and rising edge-to-edge time using timer1 updated to use Arduino ESP32 core 3. 0. pulseEdge = timerReadMicros(Timer1_Cfg); timerRestart(Timer1_Cfg); pulseWidth = (timerReadMicros(Timer1_Cfg)); Serial. begin(115200);

Which timer is used by the "Servo. h" library - Arduino Forum
The servo library uses one of the timers to trigger interrupts which it then uses to support upto 12 servos in software instead of just 2 (assumption on my part here) that a single hardware timer without additional software could support. A little bit about the servo library here - rcarduino. blogspot. com

Multiple R4 Timer Issue - UNO R4 Minima - Arduino Forum
Hardware UNO R4 UNO R4 Minima. gjacobs101 January 9, 2024, 6:07pm 1. Hello, I used Phil Schatzmanns writeup to successfully get one timer working on the R4. I tried two timers with different rates but only the first timer runs. The index from FspTimer::get_available_timer is different for each timer so it would not appear to be that.

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 racers 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 . . .

Timer Interrupt Uno R4 Minima - Arduino Forum
Hi, I want to use a timer interrupt on my Arduino Uno R4 Minima to execute a function in parallel to my program after a certain period (490 Hz). For the Uno R3 I have already managed this without problems for the timer 2 with the library TimerTwo. Since there is no library for the R4 yet, I have to set the registers myself. But I cant find the right registers in the datasheet to set the timer . . .
