I have some SA6432 switches from http://www.e3-keys.com, and awaiting for parts to convieniently hook them up.
I'm looking forward to see them working, but they're faily complicated to use. For me at least. I'm posting my first real attempt to a sketch, so have some mercy on the newby?...
Is anyone using the SA series switches?
The SA-'s need a clock signal while recieving data with a minimum rate of 60000. How do I make this?
The biggest to-do-job: graffics and fonts need to be sent in a specific size bitmap format. It would be such a relief if someone would post some fonts here... I'll get back here with the specific required specifications.

This sketch is set up for SA6432. Datasheets and application notes at http://www.e3-keys.com

/* Stores color setting for Red, Green and Blue.
Two bits set intensity for each color, in this format: 00RRGGBB (order may have to be reversed)
00 = off 01 = low 10 = medium 11 = high
example: 00111000 . meaning: Red: high intensity, Green medium intensity, Blue off. This would yield Orange.

Serial.print( 0x41); // send "color command" to SA6432
Serial.print (color, BIN);
Serial.print (0x43); // send "end transmission command" to SA6432
