I am working with the Rainbowduinos and find them very good!
Do you think I could connect the driver ICs of 1 Rainbowduino to 4 LED matrices at the same time? Guessing from the data sheet I would think that this might be ok and reliable?
Or if I go for I2C, what could I do to optimize the speed of the transmission from a Master Arduino? I only make about 4 fps with I2C which is too slow for my application.
Thank you very much,
