Hello,
I am using the dsPIC33EP16GS502 to control a push-pull boost transformer.
The PWM signals or working. I want to use the internal comparator and DAC to cycle-by-cycle limit the primary current ...

I am trying to implement cycle by cycle current limiting on an interleaved boost circuit. This makes use of PWM channel 1 and channel 2.
I am using the internal comparators #2 and #3 to measure the i ...

Hello,

Can anyone point me to an example on how to configure a dsPIC33FJ16GS502 for center aligned or push-pull PWM outputs?

Thanks,

Using the setting below does not output any PWM on either pin.
Does the timer need to be redirected?

setup_ccp1(CCP1_A5); //Put CCP1 output on A5

How do I assign PWM output to PIN_A5?
The code below still outputs PWM on PIN_A2 (default).

#byte APFCON = getenv("SFR:APFCON")
#bit CCP1SEL = APFCON.0

void main( ...

Thank you RF_Developer that was it!

The simple version still not working on A0 and A1.
Replaced chip with same results!
How can I read the APFCON register to see if it has been changed from default?

The Tx and Rx pins can be assigned to other pins (the default should be A0 and A1). I can get the serial port to work on A4 and A5 but not the default pins A0 and A1. What am I missing?
