Problem:
Now we would like to implement a factory test mode to calibrate sensor data
into hello-sensor firmware; but from PC host side, we find we can get string
from target side but when we use PUTTY to send command/data to target side
by PUART Rx (configured with 9600 baudrate and use SW polling read), we didn't
get any data from host side and we also implement UART interrupt to handle
the receiving mechanism, dont know any problem existed or something not configured
about UART?
