Thanks for your work! I've just ordered one GLCD 128*64. Waiting right now. Hope to get it to work since it's KS0108 compatible. Is there any way to reduce the data line to 4 bits so I can still sense a few buttons and digital I/O? The GLCD will take 13 pins out of 18 pins (I need to keep serial). There's only 5 pins left. I have 3 buttons and 2 inputs and that leaves no room to expand. Is there any way to sacrifice speed and support shift register for the data bits? Thanks.
