We are getting closer. Let’s say, our system clock is 180000000 Hz (STM32F429 Discovery). If we want to make a simple 1us delay, then we have to count 180 ticks to get this. If one while loop takes 4 cycles, then we have to divide our counter by 4. WebImportant Notes about ISR. Inside the attached function, delay() won’t work and the value returned by millis() will not increment. Serial data received while in the function may be lost.
