Nokia 1100 LCD with PIC microcontroller
Sometimes it is necessary to add an LCD display to our microcontroller project. We usually decide between character display such as 2x16 with HD4470 IC or other graphic displays.
Here we can see a driver for a graphic LCD display from Nokia 1100 phone which is good or even better solution than previously mentioned ones, especially because these displays are very very cheap. Driver IC on this LCD panel is PCF8814 which even though has I2C protocol support - doesn't use it. Instead it uses simple bit-banging mechanism for communication. Microcontroller that was used in this project is PIC18F1320 and source code is written in C and it can be ported to any other PIC microcontroller.
