Table LED Matrix, Weeks of debugging, column problems

[mekohler]

i'm not a C programmer but it looks like the line that says 4ms delay is your delay between rows. you could try making 259 a smaller number. i think that would get rid of your flicker but may make it even dimmer.

There is no visible flicker in person. It only showed on the camera because of the fast framerate it captures at. The only problem is brightness.

Update: I tried increasing the delay...that helped brightness a little but made the flicker noticeable to the human eye
