Timers used by Nano - Classic Nano - Arduino Forum
I have successfully used timer 2 and interrupts on previous projects but was not using PWM on any pin. On a new project I would like to use timer 2 to time certain events, but I also want to use several PWMs. I have searched, but but find contradictory information on which timers are used by which pins for the analog write function on the Nano. I would like to avoid any conflict between my use . . .

Is there a good replacement for TimerOne? - Arduino Forum
Ive seen a few threads now where people have third party libraries that depend on TimerOne and it isnt working for the R4. I have seen where a few people have been pointed to an article that shows how to set up an interrupt on one of the timers using the FSP, but it doesnt look super beginner friendly. I have been playing with the AGT timer on my R4 Minima for a couple of days and I wrote . . .

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);

Interrupt by Timer on RP2040 - Arduino Forum
Using Arduino Programming Questions. kurogedelic October 26, 2023, 4:18am 1. Hello, I am currently using the Arduino IDE and a Raspberry Pi Pico for a project. I am interested in implementing an interrupt timer functionality similar to the ISR in SAMD or the TCCR in AVR. My goal is to execute a specific function at a fixed frequency of 50kHz . . .

Using millis () for timing. A beginners guide - Arduino Forum
Part 1 It is not usually long before new Arduino users discover that although the delay() function is easy to use it has side effects, the main one of which is that its stops all activity on the Arduino until the delay is finished (not quite true, I know, but that is usually how the problem presents itself). When this occurs the new user is usually directed to the BlinkWithoutDelay example . . .

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 . . .

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 . . .
