MSP430 RFID源程序 非常有用 很好的东西(MSP430 RFID source Very useful Good stuff)

状态机的原版经典代码，单片机程序结构的革命之作(The original classic state machine code, microcontroller program structure Revolutionary Work)

C51 API 例子源码，供参考学习使用．(C51 API source code examples, learn how to use for reference.)

基于51单片机两相四线步进电机驱动程序，本程序可用42，57系列步进电机，工作方式为八拍。(Based on 51 single-chip two phase four line stepping motor driver, this program can use 42, 57 series of stepper motor, working mode is eight.)

电动汽车电气部分充放电系统的平均模型仿真程序。将开关系统转化为纯电路系统以便于分析和计算。(Simulink program for the average equivalent model of charging/re-charging part in electic vehicles. The DC-DC-AC system is modeled as a cuicuit without any swiches.)

单片机实验程序，使用的是汇编编程，可以实现用位运算，8255输入输出用PA口输入开关状态，PB口点亮相应的灯或者PC口接开关，PB口接LED(Microcontroller experimental procedure, using a compilation of programming can be achieved with a bit operation, the state of the input switch 8255 input-output port with PA, PB mouth lamp or light the corresponding PC port tap, PB port access LED)

说明：  一个labview做的虚拟的示波器程序，功能比较全，还不错~~~(To do a virtual oscilloscope labview program and functions all, not bad ~ ~ ~)

复杂的数码管动态显示和流水灯，分别用两个定时器做中断(Complex digital dynamic display and light water, respectively, two timers interrupt)

各种863.973项目申请书，对项目申请很有借鉴意义(Application of various project 863.973, is a reference for the project application )

说明：  此原理图是验证过的PCB，波特率在1.2的时候功率20DB 时，空地上，离地面高度为10米左右，测试距离1000米左右(This schematic diagram is a PCB that has been verified. When the baud rate is 1.2, the power is 20dB. On the open ground, the height is about 10m from the ground and the test distance is about 1000m)
