Hello!
I working on TWR-K70 and i would like to load bitmaps from sd card.
1. I noticed that it works slower than images loaded directly from precompiled BMP structures. So, I created Ram Drive and copied all images to the RAM - it's the same. MFS issue?
The only solution is at the beginning load all images to the structures and than display them.
Can anyone know better solution?
Another question is:
2. Do anyone know how to generate D4L files? eGUI Converter 2.1 can generate .c .h files only?
3. Where i can found explanation for image content I mean this:
const Word image[] = {
/* Bitmap dimension (W x H) */
0x00C8, 0x00C8, <- OK It's clear ;P
/* Color mode */
0x8000, <- WHAT DOES IT MEAN? How set for ex. 16M colors mode?
Thanks for any answer and regards.
Hello,
The solution is to use double buffer approach. You ‘draw' in a hidden buffer and then swap the frame buffers when is done. This is supported in eGUI 3.0 for K70 that you can download in this forums.
