New update of my tests:
SD_CARD.rar
- has background, it is more visible how alpha transparency works, as well as antialiased fonts.
- scrolling of the whole list of files using up/down buttons
- here you also can hit menu to load bitmap.bmp (one sample 32bpp included in package)
- unicode works
- faster drawing of chars. Surprisingly antialiased font is not slower than the standard one as it suppose to be. I even managed to make it faster than standard platform 1bpp font by loading the binary font into SDRAM and accessing it from there instead of the resource file.
this scrolling works similarly to the one from firmware, though I think I will make something more smooth, like preloading into SDRAM the whole bitmap in which the file list had been drawn, this will enable to extremely fast and smooth pixel by pixel scrolling of the file list, not file by file like this.
EDIT:
I've noticed something great!! By default rock compiler does not use auto optimization (there are 3 options), but only one option really optimize it, and its nr 2, but I didn't use that because I got message that licence has expired, just out of curiosity I changed the system date to test this optimization, and it really stunned me! Length of the code has been reduced from 0x365a to 0x1cc2. Maximum allowed is 0x5000 so its amazing! I feel like a dumbass worrying about every single byte of code. We can do so much :-D
