c8051f340 串口 程序This program demonstrates how to configure the C8051F340 to use routines

in STDIO.h to write to and read from the UART interface. The program

reads a character using the STDIO routine getkey(), outputs that character

to the screen, and then outputs the ASCII hex value of that character.-c8051f340 serial procedures This program demonstrates how to configure the C8051F340 to use routinesin STDIO.h to write to and read from the UART interface.
