Image Viewer V1
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.
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.
I used some resistors to make a voltage divider and sample every now and then to tell if the user press anything. Works nicely.
The LCD is 16 bit interface and so its RGB565 which is GREAT! so vivid.
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.
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.
The image loads slow because i have not had time to fix code more.
Here are some images and a video.
