I previously posted in another thread about driving a TFT at 8bpp QVGA. My thought was to use Freescales MCF5227 with integrated LCD interface. My requirements have now changed to either 16 or 18 bpp. Rather than limit myself to a micro with integrated TFT interface I am looking at other options for controlling the TFT, SPI maybe? Have also been looking at doing it in software,ie, GPIO lines, extern mem interface. Just wondering what peoples thoughts are on driving the TFT this way as opposed to the integrated controller. What kind of processor overheads would i be looking at?
