Hi,

I interfaced the QVGA 3.2" Module from embedded artists but I seem to get a very slow rate on the TFT. When running I get:

[B]Time to fill the screen = 3633 ms

Time to write 50*50 pixels to the screen = 128 ms[/B]

I scoped the clock and it doesnt seem very  nice I have attached an image, this is using EA LPCXpresso base board.

Any thoughts?

Hi,

It seemed that another line was interfing with the clock. After inserting the jumpers for the 7 segmet display the lines was clean.  :D
