how do I?

18 May 2011

Hi!! I'm working with a lcd with the ssd2119 controller, Im reading bitmaps on a SD card with the readPixel() command, but it seems to be too slow!!(about 3 ms per pixel on 24 bits) I know that those 3 ms are because of the SD card (I get 15 fps when i send raw colors to the LCD) the question is: Can I get the entire row of colors of the bitmap at once? How do I do that?

-I'm working with parallel bus,24 bits of color and sending data using Portout() command -I'm also reading data from the SD card with SPI running at 12Mhz, I noticed that if i change the speed to 500Khz the speed is almost the same!! :(
