Embedded Artists 3.2" QVGA
I have just started experimenting on a color LCD display. Can I use any of these programs to control 3.2" QVGA color display from Embedded Artists? Thanks in advance.

The user guide describe two different versions of the display. V1 has a IS2102B controller - V2 a SSD1289.
Both controllers can be driven with a mbed board. For the SSD1289 you can find : http://mbed.org/users/ttodorov/code/TFTLCD/ This lib support only 16 bit parallel interface, but if you want to use the serial interface you only have to change the WriteCmd and WriteData function. My SPI_TFT lib is using a different controller. There are related registers, but they will differ in detail. It can be a starting point to make a lib for this controller.
Thanks Peter for your quick help. As you have already mentioned, SPI will be a better choice for mbed, as it runs out of pins pretty fast. Since I am a beginner in this, it will be of great help for me if you can post a small example program with the modified functions for SPI and the corresponding wiring diagram, iff it does not take much of your time. Thanks again.....
