I've tried some things with dma, but now my arduino doesn't work anymore. I have seriously no idea what's the problem.Edit: It works again. I pressed the erease and the reset button at the same time, and were able to upload a sketch again. After that everything worked well again.
Lucky men, I know this kind of happiness...
Yea, first I thought it has broken. But then I just tried some random things, and then by purpose the bossac com port connected to my pc.
By the way, I changed the loop (with asm code) and now it is 330 px width.
