So i thougt, screw it. I got a 64x64 matrix to test the full capabilities of the driver.

First of all, yes! The DCDC can drive it on full tilt.

However only for about a minute until it overheats again. Lets improve in this again in version 4.

Also: rendering 32 lines causes quite some flickering. Also the sprite feature tends to break down under quite some flickering.

So i had to rewrite the whole thing.....
