51-SPI-ST7585,用于C51 SPI方式驱动ST7585(51-SPI-ST7585, for SPI C51 mode driver ST7585 )

MC9S12DZ60时钟初始化程序, C语言, code warrior 软件(initial program of MCG, C language，code warrior software)

用RS232实现单片机与PC的串口通信,在KEIL C环境下编写(Realize single-chip microcomputer with RS232 serial communication with the PC, in KEIL C environment to prepare)

用数码管显示电压，发送到串口，然后有高低电压报警，只有部分代码(Display voltage with digital tube, send it to serial port, then alarm with high and low voltage, only part of the code)

说明：  一个自写的ClistCtrl打印类，直接引用就行(a written ClistCtrl Print category applied directly on the line)

说明：  它是关于80C51单片机的原理介绍和使用其开发的过程，有具体的实例。(It was introduced on the 80C51 microcontroller and use the principle of its development process, with specific examples.)
