Serial Communication Example

I am looking for an example of sending data from the LattePanda CPU to the onboard Arduino. I have many hours into trying to make this work and have thus far failed.

Please see this thread: viewtopic.php?f=6&t=1429

In the thread you will see that even trying to send data from the Arduino Serial Monitor doesn't work. You will also see that the same code works fine with an external Arduino.

Thanks
