Please somebody help.
I have a Seeeduino Atmega 328 and a Rainbowduino Atmega 328 and a 8x8 RGB LED Matrix but I cannot get them to work. I have tried mTX control but no success and a number of sketches found on code.google but I am about to give up. One time I got the display to show 0, 2, 3... and so on with I think was Seeedmaster but I want some fancy patterns.. anyway...
On the Seeeduino, some forums are using the analog pin 5 and 6 and others are using digital pin 0 and 1. It is a bit confusing.
On the Rainbowduino, does it matter on which side you are connecting the SDA or SCL?
Is it enough to power the Rainowduino from the 5V on the Seeeduino?
The switch on the Rainbowduino, does it matter if its set to JST or not when you use the 5V power from the Seeeduino?
The switch on the Seeeduino close to the USB connentor, what position?
