dmx pic code with rpm's dongle

[intwoit2002]

I have just built 2 of the dongles by RPM, they are great. I am having a terrible time to get it to work with a Renard 64.

I am not sure if I have dongle problems, although I do think I do not have the drivers installed correctly.

I am using the DMX version of Phils code from the Wiki, all I see on a scope is data going (some kind) but no blinky.

Does anyone have experiance with either of these items.

Not very computer savvy, just enough to get in trouble. I see a data stream out of the dongle that look like square wave with a period of about 45 Microseconds.

Any help would be greatly appreciated.

Thanks,
Al

I don't have one of Robert's dongles, but I would tend to think the problem would be either the wiring or the renard. I'm assuming the renard works fine with the standard renard firmware.

A few things I can think of to check:

Did you adapt the wiring from the dongle to the Renard. The pinout is different. This is assuming robert's dongle uses the standard DMX pinout, which knowing him, i'm sure he did.

Wire DMX Pin Renard Pin
White/Orange 1 5
Orange/White 2 4
White/Brown 7 7

Do you have the start channel set on the first PIC to what you want the start channel of the board to be? Do you have the start channels of the other pics set to '1'?

The Renard works fine on normal pwm code.

I made a crossover like you described already, same pin out.

The Pics are programmed all for address 1 just for the start.

I am setting the channels from 1-64 and using the DMX pro plugin.

I think I am doing something wrong on the driver side or programming the PIC.

Not sure how to check the PIC.

Thanks for your input.
