基于Keil的51工程-1602移位显示(51 works based on Keil-1602 shift display)

TCS3200传感器捕获方波频率，可以根据频率变化识别外部光源颜色(TCS3200 sensor to capture a square wave frequency, the frequency change can identify the external light source color)

这是基于开发板LPC1114的源码程序，是用C语言编写，用于实现系统定时器的配置同时它也是一个完整的模板，可以在此基础上添加其他程序用于开发板的学习，是一个完整的模板，可直接使用。(This is a source code program based on the development board LPC1114. It is written in C language. It is used to realize the configuration of the system timer. At the same time, it is also a complete template. On this basis, other programs can be added for the learning of the development board. It is a complete template and can be used directly.)

说明：  ALIENTEK STM32开发板SYSTEM文件夹，采用V3.5库的头文件，使得代码可以完美移植到库函数里面使用，不过注意，在新建工程的时候，请在：Options for Target-->C/C++ 选项卡里面 Preprocessor Symbols 栏定义你的STM32芯片容量。比如:ALIENTEK 战舰STM32开发板用户，使用的是大容量的STM32芯片，则在Define栏输入：STM32F10X_HD 对于STM32F103系列芯片，设置原则如下： 16KB≤FLASH≤32KB 选择：STM32F10X_LD 64KB≤FLASH≤128KB 选择：STM32F10X_MD 256KB≤FLASH≤512KB 选择：STM32F10X_HD(ALIENTEK STM32 development board SYSTEM folder, using V3.5 library header file, so that code can be perfectly transplanted to the library function to use, but note that in the new project, please: Options for Target - > C/C++ tab in the Preprocessor Symbols column to define your STM32 chip capacity. For example: ALIENTEK warship STM32 development board users, using a large capacity STM32 chip, in the Define column input: STM32F10X_HD For STM32F103 series chips, the setting principles are as follows: 16KB < FLASH < 32KB Selection: STM32F10X_LD 64KB < FLASH < 128KB Selection: STM32F10X_MD 256KB < FLASH < 512KB Selection: STM32F10X_HD)

本例是用51单片机的键盘解码程序，亲试好用(This case is a keyboard with 51 decoding process, pro-test handy)

建立上位机与PLC之间的modbus（RTU）通讯。利用c#实现(Modbus established between PC and PLC (RTU) communication. Use c# achieve)

LED显示屏开发，医院体检中心推送消息到LED(LED develop)

基于stm32f103r8t6的串口例程，实现数据的收发方式(Based on stm32f103r8t6 serial port routine to achieve the data transmission mode)
