说明：  本程序为单片机对四相步进电机的控制，使用L297，能够通过键盘设置电机的转动角度，精度为1度，文件夹里附有源代码和仿真电路图(This procedure for the single-chip for four-phase stepper motor control, use L297, set up through the keyboard of the rotating electrical point of view, an accuracy of 1 degree, with a folder in the source code and simulation circuit)

说明：  关于freescale单片机S12/S12X系列的串口bootloader，资料是freescale代理给的，很有参考价值，使用codewarrior 5.1编译环境，C语言编写，便于移植和改写！(This is a S12/S12X serial bootloader on the Freescale microcontroller based on CodeWarrior 5.1 compiler environment, Freescale agent given to me, it's very valuable reference . profit from C language, it's easy to be transplanted and rewrite!)

单片机AD功能实例，使用1602显示电压(SCM AD function example, the use of 1602 shows the voltage)
