Ok this uses my LPC2103 Header board from Olimex. I didnt use the IC alone because i didnt want to go through a hassle if it wouldnt work. Now that i know what to do and how exactly everything works in place i can make a version 2.<\/p>\n
I can view BMP files using a Navigation switch from sparkfun. The trick here since i didnt have enough pins was to make the switch work using ADC of the mcu.<\/p>\n
I used some resistors to make a voltage divider and sample every now and then to tell if the user press anything. Works nicely.<\/p>\n
The LCD is 16 bit interface and so its RGB565 which is GREAT! so vivid.<\/p>\n
The quality is better than in video and pictures. I also included a boost converter on board since the LCD backlight needed 8v to turn on nice and bright. I might use a Mosfet and PWM that backlight.<\/p>\n
Power is from a 5v usb micro plug. The images come from a SD Micro. I am using a 64MB card i found around in case i made a mistake. But this can ready SDHC cards so >4GB can be used. I used ELM Chan Petit FS for file system control.<\/p>\n
The image loads slow because i have not had time to fix code more.
\nHere are some images and a video.
