Hi,
I’m running FreeRTOS on the ATMega32 and need to sample PWM input from a temperature sensor… since other stuff is going on as well, a great deal of interrupts are happening… atm i’m using a 16-bit timer and external interrupt for PWM sampling, but because of all the other interrupts, theres a great deal of jitter on the PWM sampling… To eliminate that, my only option is to use input capture i’d think, but that is only possible on the 16-bit timer, which is occupied by the kernel…
would it be possible to run the kernel on an 8-bit timer without issues (except for reduced granularity on the possible tick rates) ?
cheers
