This chip is about 10 times weaker or more than what you have in your mp3 player. I know that my mp3 player displays jpgs instantly, let alone mpeg4 video of 320x240@30fps.
@bienvankhat Could you recommend one that is good for jpgs and LCD? I've been looking at fez coz it runs .net but there may be better options. What say U?
I think the main problem is the USB port, probably is in low speed mode and probably the code was wrote on C.
I have a project running at 1MIPS on a 18F6585 and can write the whole screen about 3 times faster than that application; but was wrote on pure assembler.
Not necessarily. Your MP3 player may be loading the graphics data to the LCD first, before enabling the screen. Therefore it looks like an instant display but it is not. You know that pause you get between viewing pictures on some digital camera devices? Same thing - they're loading the data from the removable media and sending it to the display. When this is done, they enable the display.
Seems like a really cool board but next time get a camera that is focused!!

Right! PIC24F is not designed for Image and Video applications.
I just want to test the LCD and how much the little PIC can do.

Hi is the techtoys board? up is a pic? is hard to use?
very good!

Yep, It's PIC24FJ256GB110. But I design the board and schematic myself.
It's not hard, there's libraries in Microchip website.

Can you write an app note about it ?
