hey all… after my rainbowduino is arrived i played with several firmwares. now I need some help from you guys.
what I want is display a precomputed buffer (computed on my workstation) on the rainbowduino. so i send the image via serial directly to the rainbowduino. did I understand it right that there is no function yet which do that? i tested several firmwares (mtXcontrol, Raibow_conmandVertion_Bate, rainbowduino_v1_0_5, Rainbowduino_v3_0h, RainbowV1.1Serial) without success.
rainbowduino use 12bit/per pixel - so to draw a white screen i would send 64 times 0xfff (or 768 times a 0xf character, this would mean a full screen buffer size is 96bytes), is this right?
is it possible to communicate with my first rainbowduino serial (from my workstation) and the rainbowduinos would talk to each other via i2c? example
so i can send to my rainbowduino: drawBuffer(target2, bytebuffer).
