|Ericsson Cell Phone Display GA628|
Based on a WWW publication I found, I designed a software written in
standard C for the MSP430 family. It can easily be modified for different micros. (be aware you will have problems to go back!)
The GA628 display provides a 12 character alphanumeric display , some icons in the second line and power consumption of some 100 uA. It can easily be connected to the hardware, simply by soldering some wires. The only disadvantage is , it needs a 3.3V power supply and something around 5.6V. However, this code and the MSP430 provides a clock for a simple charge pump, realized with 3 diodes and 3 capacitors.
