Hi Vacpress,

The Two LEDs are for the PWM output and the Other green led is just connected to Vdd to indicate that there is power on the board.

I built the board for two reasons -
1. Get a grip on all this USB stuff
2. Use it as a programmer for these chips.

I added a DB-9 / Max3486 chips so that I can learn a bit about serial to usb as well.

Now can someone please explain how to use Microchip's CDC? http://www.microchip.com/stellent/id...param=en022625

No plans for Dot net. We use PowerBasic around these parts.

Cheers
