51单片机模拟串口SPI方式接收和发送数据

51单片机开发的双路冷气机自动切换报警控制器-51 MCU development of dual air-conditioning automatically switch alarm controller

x25045的编程应用，它具有512字节的EPROM，看门狗，复位信号等，是MCU不错的外围芯片-x25045 programming application, which has 512 bytes of EPROM, watchdog, reset signal, MCU is a good peripheral chips

数据块的首址在R0中，字节数在R7中。 单字节无符号数据块排序（减序） 影响资源：PSW、A、R1、R6-the first data block site of the R0, the total number of bytes in which R7. No symbol single-byte data blocks ranking (by order) affecting resources : PSW, A, R1, R6

这是52单片机串口调试程序，通过此程序，可以使单片机于PC机通信-This is the 52 single-chip serial debugging process, through this program will enable single-chip communication to the PC
