i have a question about the rainbowduino firmware, can someone explain me, whats exactly the purpose of the gammatab is? i dont get it!
my problem is, that my output on the ledmatrix looks a bit flat/dimmed. I can workarround this issue, if I multiply the color with itself (rr/255, gg/255, b*b/255 then convert to “rainbowduino” format) and thus get more contrast. I ask myself if there is another way, perhaps with this “mysterious” gamma tab?
