Fast question on PWM

Post by daniele.caprini » Thu Nov 27, 2008 12:06 pm

Hi guys, I have a little question for you.
I have generated a square wave with PWM and 50% duty cycle.
The square is very good but is 3.3Vpp.
How can I generate a square at least 5Vpp???
Thankyou very much

No way to do this with the dsPIC.
I think you should convert the output voltage from 3.3 to 5 on your own.
Look for a voltage converter on the web.
Regards.
