Designing microcontroller project

Few reminders when designing an uC-project:


General on inputs:

  • Primarily use first all external interrupt and analog pins. Make pads for unused “special” pins, for example external input/analog-pins.

Pulse measuring:

  • Do you need to measure pulses? Use external interrupts whenever possible, they are simple to do and really accurate


  • If generating pulse out by delay remember that interrupts make the signal jitter.
