I need to read in dmx 512 information and provide multiple PWM outputs.
Can it be done with just one Pic or would it be best to have one Pic dealing with the dmx info. and another dedicated to the PWM outputs?
Can someone advise me on the best way to provide multiple PWM outputs at around 2khz eg. software example or detailed explanation of how this is done - probably using the capture module?
many thanks for your time.

i have used the dm118, the 8 channels pwm(100hz, 256 grey degree) is so good for led:) |

| You could use one of Atmel's MCU they have up to 16 PWM channels. |

| I know this is an old post but I have been testing the code and it works great as it stands. However I would like to utilise all availble output pins on the 18f252 (16 pins) and I'm having trouble getting this to work. I thought it would be as simple as uncommenting the references to portb and port c in the two interrupt routines but I get strange results - has anyone else tried this?? |
