First double-check the wiring, be sure your wiring and the code agree on interface mode (4 or 8 bits, hi or lo nybble, ect), then try the code from one of the mchip app notes. If it works compare code, if not try another display unit. I've had luck with mchip's app note code, parallax's app note code, and CCS C compiler LCD driver. I use a part called the LCD Backpack by Scott Edwards Electronics to quickly test display modules, it allows you to plug your module into it with a ribbon cable, then send rs232 data from PC, PIC, BASIC Stamp, whatever. Very useful for eliminating hardware problems. He doesn't have a web site but Parallax sells them. ---------- Bruce Cannon Style Management Systems Remember: electronics is changing your world...for good! ---------- > From: Wayne Bennett (by way of Wayne Bennett ) > To: > Subject: [PICS] LCD interface > Date: Wednesday, May 28, 1997 1:02 PM > > Has any one had much success with interfacing the 16C74 with an LCD(hitachi > LM016L).
