Hi,

I'm using the PIC16F1824 which is a 14pin IC.

I am using 2 PWM channels (CCP1 and CCP2) to drive a DC motor differentially for forward and reverse positional control.

CCP1 and CCP2 are located at pins 5 and 7 of the IC which are on the left hand side of the chip.

The PIC16F1824 supports 4 PWM outputs (CCP1, CCP2, CCP3 CCP4).

I would like to use CCP3 and CCP4 instead due to PCB layout reasons which are on pins 11 and 9 respectively since they are on the right hand side of the IC.

Does Flowcode support using other PWM modules aside from CCP1 and CCP2. If so, how do I use the CCP3 and CCP4 modules when using the PWM macro in flowcode?

Thanks,
Paul

Hi Paul,

Flowcode v5 supports the additional PWM channels. Otherwise you could maybe use software generated PWM using a timer interrupt as shown here.

you can make simple pwms that go to any pin on the micro http://www.matrixmultimedia.com/mmforum ... 26&t=11590
