Nokia 7110 GLCD driven by ARM
I posted this in the Proteus board before I realized that it should have been here. But here is a little program I have been working on the last week. It is the GLCD on a Nokia 7110 cell phone (SED1565 driver). the goal is to drive it with an ARM mcu.here is the code - it runs fine, and is about 80% done functionality-wise. You are free to use it.
it was developed on Keil MDK3.70 demo.

(原文件名:nokia 7110 glcd 2.PNG) 强帖留名 mark Thanks millwood0 GOOD1 some history of the code: the code was originally developed by somebody else in CCS. It had serious timing issues and coding errors when I was trying to migrate it to PICC. then I realized that for what I wanted to do, pic isn't fast enough so I thought about migrating to ARM. that's why you will see a lot of lines that I have commented out that refer to htc / pic.
the code still has some issues and inconsistencies that I am trying to fix soon. But for now, it should work most of the time.
here is a picture of a menu someone developed with this library.
