Recently, I was trying to use the button to select the specific actions.
Actually, the program is built successfully and it can show the "UART Start!" via serial port, but there was no button response.
Does there has anybody meet the same problem, or I just do the wrong flow in the program? How to fix it?
BTW, the program was developed by SDK11 and based on "uart_pca10028"
