Hi, was there a reason, why for ATmega256x, the timer2 does not run with asynchronous clock ? (free run, with overflow ints, using external 32kHz osc) When crystal frequency (NUT_CPU_FREQ) is defined, ticks are per 1ms. We intend to use longer OS granularity. Has anyone tested this ? I was not able to google out discussion about it. Dusan
