Hi Jan, > i have an LCD with the M50530 controller.

Strange. Very strange. At least these signals are necessary: DB0-DB7 I/OC1 I/OC2 EX R/W GND VCC Vref which gives 15 pins. I could imagine that "shield" is not necessary (as its normally hardwired to GND). Are you really shure it's a M50530? Are there other chips on your display? Maybe it's another microcontroller which has aonther interface with 14 pins, and controls the M50530 itself. As a last resourt, you'd have to follow the signals on the print, and find out where the 14 pins end at the M50530. I know this is difficult (I've done this several times), but it's possible. bye, Michael -- Michael Reinelt Tel: +43 676 3079941 Geisslergasse 4 Fax: +43 316 692343 A-8045 Graz, Austria e-mail: re...@eu... |
