With al lot of fun I use the EMX module, only I see that I have problems when using a a 800x480 TFT screen. The screen is works ok, but when I use the sd card to read a bmp file, you see the TFT screen flickering.
The solution should be to change the lcd clock, but when I do that you some litte flickering in the screen. Also an screen update from the sd card cost a lot of time, more then 5 seconds.
The strange of the story is, when I use an USB stick to read a bitmap file, the flickering is not present and also I can use the good lcd clock speed. But the time to show an picture is very slow.
So I looked and saw that NXP has an new microcontroller the LPC1788 @ 120Mhz and SDRAM clock @ 80Mhz.
My idea is to make a board with a 16-bit flash and a 32-bit SDRAM and the LPC1788, the advantage I think is the use of 32-bit SDRAM this will give an lower load on the LCD bus, so the programm can works faster.
The question is, is it already possible to port the micro frame work to the LPC1788 and are the any suggestions for this board?
