基于C8051F340的串口通信测试程序，硬件上电平转换用MAX-C8051F340 serial communications test program based on the hardware level conversion with MAX3232

c8051f02x DAC控制电源芯片max3232输出电压。-c8051f02x DAC output voltage control power chip max3232.

这个例程是基于STM8单片机MAX232通信,包括串口接收和发送函数里面!-This routine is based on STM8 single chip MAX232 communication, including a serial port to send and receive function inside!
