[En-Nut-Discussion] I/O pins control

[Michael De Backer]

Hello,

I'm beginning with the Charon II Dev Kit too. Looking for the same
answers :D

How can I use one pin to generate pulses (25,50,70 and 100ms) ? Is it
possible to use NutTimerStart and make the pulse in the callback routine
? Is it a better way to do that ?
