http://home1.gte.net/res0p7vh/io_sch.jpg Replace the 74HC573 with 74LVT573 or 74LVT574. (same pinout, but 3.3v) Not really I/O, just O. This could drive 8 LEDs and be proof of concept. Code-wise write a byte to same address as tty uart. Anyone want to start wire-wrapping? _________________________________________________________________ Dream of owning a home?
