Hi Janos,
Sorry to reply a bit late. i just added these two lines to my code and it
worked fine:
SET_BIT(DDRE,3);
SET_BIT(PORTE,3);
if i implement McuPowerOverride.LowestState() , should I take care of the MCU
power state for all my application features or just only the Timer 3 knowing
that my code uses ADC and Radio?
Best regards
Hafid

Hafid,
Most probably, the MCU goes to sleep and the timer is not ticking. To
prevent the MCU from sleeping, implement the McuPowerOverride
interface and wire it to McuSleepC.
