Continuing with my GLCD stuff. I find that it is too much for one PIC to handle a GLCD + my main program since screen refresh time is important. This GLCD uses 21 pins. Anyways, an additional PIC is cheap. So, I plan to make a dedicated LCD PIC that would take in a command, then draw it on the screen. The built in controller can only draw a pixel in any color, or read a pixel color.
Some commands that could be sent to this dedicated chip to do something on the screen: 1. draw some text 2. draw a shape 3. draw a pattern 4. draw an image from a image already be stored on the dedicated PIC 5. draw an image from data sent from the master (slower) 6. draw a button 7. maybe some kind of GUI, Maybe also feed back info from the touch screen (I haven't decided on this yet). May I can tell what button on the screen was pressed and send it back to the master. A good board for everyone would give an option to use either I2C, Serial or SPI. SLIP may be good for packets.
