As reference I'm looking at src/drivers/scr_ecos.c but this supports color mode only (RGB 555 and RGB 565) and, for istance, I can't understand which pixel format I have to use (MWPF_PIXELVAL, MWPF_PALETTE ...) and if rmask, gmask and bmask have to be handled. I'd like to find a driver supporting monochrome or grayscale panels to use it as starting point. Anybody can provide such an example? Any hint or advice will be appreciated, too. Thanks a lot in advance, llandre DAVE Electronics System House - R&D Department web: http://www.dave-tech.it email: r&d2@dave-tech.it
