Hi,

since I could not find another way to send in a patch, I am using the Tracker :)

Attached is a patch that adds support for 'KarateLight' devices. It is a 8 (or with extension-pcb 16Channels) RGB-Dimmer. Schematics and Firmware can be found here: http://ca.rstenpresser.de/~cpresser/data/karate/

Without the patch the prefix and color data were send in two messages. Since Karatelight expects this to be just one message, I have changed the code to always send the prefix and color-data in one burst. This should not break other devices. At least, the AtmoLight device still works fine with the patch applied.

Greetings Carsten

Nice, but why the change of putting the prefix in the buffer?

The Firmware has no state-maschine working the serial input. So the whole input needs to be processed at once.

I could change the KarateLight firmware, but I dont see a particular reason why one sould send the prefix and the data in two bursts. So I changed the boblightd code :)

I've added the first part of the patch in r333.

I agree that this is a nice optim, but it won't guarantee that the data gets sent in one burst.

Please use whichever is most robust for enduser!

Fixed in r337. Now someone just needs to test it I suppose.
