I've only been reading this list for a month or so, and already picked up numerous pieces of interesting information. I am also new to the PIC processor, and am about to start a new project using the 16C65 and would appreciate any assistance on the following problem: Microchips' Ap Note AN563 gives some pretty specific info for the hardware and software for using a PIC as a multiplexed LCD driver directly from the pins, but the example is for a simple 2-backplane LCD. I would like to use the same technique to drive a 3-backplane LCD... basically a 3 3/4 BCD digit LCD with a few annunciators. Is such a thing possible without violating the DC voltage spec of the LCD? How complex is the code, and can it be done with a '65? Any code examples would be appreciated...
