Hi
I just ordered a Crystalfontz CFAG14432B 144X32 graphics LCD display which is using a Sitronix ST7920 controller, although I have found a driver on this forum, it unfortunately does not seem to work. I have gone over the data sheet from Sitronix and although everything seems match correctly, (sequences and values)I cannot get it to work other than just plain random garbage on the screen, after spending a couple of days pulling my hair on this thing. I guess I can start from scratch all over. I am using V4 of the CCS compiler and a slightly modified version of glcd.c if anyone has had any experience with this graphics module any hints would be appreciated. Thank you. Confused

Is your LCD jumpered for the SPI interface or the parallel interface ?
