Hi @all,

I've googled but not found...

Is there a documentation about programming the 4 led on a CFA-635? I want to use it in lcdproc, but it looks like I have to code it myself.

tnx Frank

Programming the LEDs is described in the manual here: http://www.crystalfontz.com/products/document/2372/CFA635-TFE-KU_Data_Sheet_v2.1.pdf

For example code, see the WinTest635 source code here: http://www.crystalfontz.com/product/635WinTest

solved

for lcdproc:
"output <number>"

the led-color is set by a bit-mask: 1111 1111
first block sets the color of the led to green, the second block to red.
if both --> orange
<number> is the byte or hex value of the bit-mask

thanks
