Hello all.
I'm very new to the world of arduino and have gotten myself an Arduino mega 2560 as well as a rainbowduino and rgb matrix.
I am running the neorainbow firmware on both devices and am trying to communicate with the examples in the firmware package.
I have edited the wire libraries as stated here: Rainbowduino fun – aka neorainbowduino
And I hooked up everything so it appears correct.
When I run the 12c scanner it finds my rainbowduino!
When I load the simple example it runs showing random pixels on the matrix but I get some errors after a while as follows:
com.neophob.lib.rainbowduino.Rainbowduino waitForAck
INFO: No serial reply, duration: 30ms
When I run the invader example I get no display but the sketch runs without error in processing.
Anyone got any ideas? I've been scratching my head for over a week on this one.
I was wondering if there are any notable differences in the way a mega 2560 handles i2c compared to other arduinos. I know the pinout is different but is that all?
