WebMay 26, 2024 · You have flag++ in the ISR but flag == 1 in the main thread - safer to test flag != 0. Nowhere in your question do you mention which ATmega you are using, and they are not all the same. You should fix that. You don't need the delay, the LED changing state either way would indicate that the interrupt occurred. WebMar 9, 2024 · The Atmega 168/328 timers. The ATmega328P has three timers known as Timer 0, Timer 1, and Timer 2. ... PWM", which will be described below. The timer can either run from 0 to 255, or from 0 to a fixed value. (The 16-bit Timer 1 has additional modes to supports timer values up to 16 bits.) Each output can also be inverted.

WebJul 30, 2006 · Frequency Correct mode of the Timer on your Atmel ATMega chip. In Phase and Frequency Correct mode the timer starts at zero, counts up to a user defined value called ICRn (n is the timer number. In our example, we will use Timer1 and thus ICR1), and then counts back down to zero. We want the counting up and down process to take … Web3. Here: ldi r20, 0b00000010 ; CTC mode, int clk; sts TCCR1A, r20 ldi r20, 0b000000101 ; prescaler /1024 sts TCCR1B, r20. you are setting the bit WGM11 on TCCR1A. The timer then runs in mode 2 (PWM, Phase Correct, 9-bit) rather than mode 4 (CTC). Share. Improve this answer. Follow. answered Nov 26, 2024 at 15:50.

Timer2 can be either synchronous or asynchronous, and as such has its own Prescaler. Since we are using the Prescaler to sync up the timers to each other, we can only do it in discrete steps – Timer0 and Timer1 can be sync’d, or Timer0, Timer1, and Timer2 can be sync’d. 2.
