I have managed to get I2c and some gpios working on the BBB using c++ as the development tool. WIth UART I can send data using the ttyO4 port, but I am unable to receive any data on it.
I have used the code given in this site…serial port example code
Please could anyone tell what is wrong ?? I can send data but not receive.
Could anyone point out some example code that can do this…???
I know the hardware is working fine as I have checked the pulses on the RXD line.
