Hi,
I am after a bit of help with writing a flowcode V3 program to control 4 DC motors. The PIC i am using is the 16F877A and it only has 2 PWM channels. Is this possible using the PWM modules? If not can i round the problem a different way still only using 1 PIC? My project is 4X4 traction control. Any advice or example flowcode programs would be a great help.
Thanks Mike

Hello !

You can use the 18F4431 who have more than 2 PWM and use c code or you can make a macro interupt who simulate pwm in software.

Flowcode currently only supports a maximum of 2 PWM channels on a device.

We hope to allow more soon but yes at the moment using software driven extra PWM channels is a good way to go.

See here for an example. (PWM LED)
