说明：  sd卡初始，由于SD卡使用SPI模式，并且是块读取(512Byte),所以需要单片机提供大于512的可用RAM，以供缓冲使用 这里可以选择STC89c52RD+、STC89C58RD+、STC89C516RD+，后缀RD+表明扩展RAM是1024字节，RC表明扩展RAM256字节(sd card original, because the SD card using SPI mode, and is a block read (512Byte), so they need the microcontroller to provide more than 512 of the available RAM, for buffer used here can choose STC89c52RD+, STC89C58RD+, STC89C516RD+, the suffix RD+ that extended RAM is 1024 bytes, RC that extended RAM256 byte)

巡线小车 基于pid算法 光电传感器 可以平稳运行 含有led屏(line follower with pid control)

此程序和上一个程序是用于51单片机和430单片机的通信，通信方式为单工，430做主机51做从机(This program and a program for 51 And 430 single-chip communication, means of communication for the simplex, 430 to do Host 51 to do slave)

AVR各种应用小例程,包括各种常用传感器，液晶，步进电机，语音等等(AVR application, common sensors, LCD,stepper motor,voice, etc.)

2X16和2X20的LCM C51 驱动代码(2X16 and 2X20 LCM C51 driver code)

C语言写梯形图控制V11(三菱PLC101例子之最好21例1-13)(C language to write ladder control V11 (Mitsubishi PLC101 best examples of 21 cases 1-13))

一个测试Radius的工具,可以测试Radius服务器是否正确(tekradius this is a good test tool)

p1.5脚控制灯。 当灯点亮是，把域值增大。 光传感器通过AD转换。 使用STC12C5404AD调试通过。(P1.5 pin control lights. When the lights lit is to increase the domain value. Optical sensor through the AD conversion. Debugging through the use of STC12C5404AD.)

说明：  STM32F103,可自动稳流，调节功率,双路ADC,一路DAC(STM32F103, automatic current stabilization, power regulation, two-way ADC, one-way DAC)

关于nokia5110的使用程序，本人在实验室亲自做的，保证正确！(Nokia5110 use the program in the laboratory, I personally do to ensure that correct!)
