Finally it worked! All because of the SD card. I was using a high speed 16GB card, not sure why it wasn't working even though it was formatted to FAT32.
v0,v1,v5 files work (but only GREEN and some BLUE), except @tribble's fireworks.ild file
And lastly, the laser projector I have is two color, GREEN and BLUE. That's why v5 file is displayed in parts. some lines are missing which maybe the RED... YUP confirmed, I just opened it with zILDA.
My next task is to find a way to write .ild files. @james As much as I love to I cannot build the DAC (yet) because I don't have the time and secondly the company will not have music, just static display (I know, I might just convince them for the whole project because I am interested).
@mixedgas, thanks a lot for the zILDA viewer. If you have a recommendation for a tracer/animation software, that would be great. @james I am going through your CLI based LaserBoy and even though I do CLI python programming this "looks" insanely complex! I love a challenge, lets see how far I get with drawing on LaserBoy.
