I want to use UART1 on beaglebone black to send a string of characters to a arduino. As far as I can tell, I’ve been able to correctly mux uart1 pins by using these instructions → http://learn.adafruit.com/introduction-to-the-beaglebone-black-device-tree/exporting-and-unexporting-an-overlay
and http://hipstercircuits.com/enable-serialuarttty-on-beaglebone-black/
Now the problem is that I do not know anything to do with it. Can you can help me by pointing to a c++ code to output data through tx at certain baud rate. Also, let me know if these instructions are missing anything.
-thank you
