Hi all thanks for your reply
Well I actually dont want a level shift.
The max amplitude @ the arduino due is 3.3 Volt.
I just need to variy it like having 10% of the 3.3v or 50% esc.
So no external hardware or so
I attached my code at the first thrid I posted so can aye one tell me wht I need to be able to vary the aplitude of the pwm signal from 0v till max 3.3 volt ?
Thanks in advance
