Hi Alus,
What a coincedence, I have a few decent LCD graphics displays but am
sorely pressed for time to write a device driver...
Is 128x64 enough resolution? I have used these displays on other
boards/processors, but not with Linux. It is backlit. It has a 5v
interface, so a some voltage translation will be needed. I can make a
circuit for that. The MAX chip _might_ provide enough current to run
it, but I am pretty sure there is a 7660 voltage inverting charge
pump on board. That means that negative voltage will not need to be
stolen from elsewhere.
They are from Emerging Display - EDT EW13B10FLY and use the samsung
S6B0108A01-00 and the S6B0107B01-00. I can provide code snippets
in 'C' and maybe a datasheet.
If shipping is reasonable, I would consider it a good trade to
provide two displays in exchange for the device driver. I have both
the 7200 and the 7250 but am only using the 7200 for development. The
two boards are esentially the same.
Any interest?
