You could certainly do this clock in something like a Xilinx Spartan device. TFT data rates are generally a bit too fast to do useful things with PICs, although with a small amont of external logic (small cpld) to take care of the syncs etc. and help format the data, you could maybe do something. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
