Hi,

I have been reading AVR055 "Using a 32kHz XTAL for run-time calibration of the internal RC". The code does a calibration only at the beginning. My question is, is it possible to calibrate the RC clock many times in the loop because of changes of temperature all the time?

Thanks
Owen

Yeah just call the calibration every 10 minutes or half an hour or whatever suits you.
