Arduino microsecond timer interrupt. .

Arduino microsecond timer interrupt. You want to trigger the interrupt every 104 microseconds, so you want 208 ticks or OCR2A = 207. We’ll discuss how the Arduino micros () function works and what are the use cases for it. This timing function offers various resolutions compatible with different Arduino families. In this tutorial, we’ll learn how to use the Arduino micros () function instead of delay. In your example the compare value is 249 which is 250 ticks because they are zero indexed. The micros () documentation notes that the return value will always be a multiple of 4. This number will overflow (go back to zero) after approximately 70 minutes. Sep 15, 2015 · On the 16 Mhz UNO, when you set up the timer with a prescaler of 8, every tick is . Thus, the compare period to trigger the interrupt is 125 us or 8khz. Jan 23, 2014 · Arduino Timer Interrupts: Timer interrupts allow you to perform a task at very specifically timed intervals regardless of what else is going on in your code. In this instructable I'll explain how to setup and execute an interrupt in Clear Timer on. Is there any way to get a higher resolution microsecond click, preferably down to the 1 microsecond level?
