Hi promacjoe,
Thank you for your reply.
I read the schematic exactly as you described.
If JP4 is set, I have the LED on at 100%, full 3.3V.
So I've desoldered JP4 and soldered JP5 to use PWM.
In my test code I just used analogWrite(7, 100); on setup section and it doesn't turn the LED on.
Am I doing something wrong ?
Thank you,
Giulio
