串口通讯232，接受上位机发出的指令来控制一个继电器的开关状态(Serial communication 232, to accept the instructions issued by the host computer to control a relay switch state)

这是一个CC1101的PCB板子原理图和PCB文件，给大家设计带来方便(This is a CC1101 the PCB board schematics and PCB files, designed to bring convenience to everyone)

51单片机的模拟串口的一个小程序，新手了解学习模拟串口看一下可以(51 SCM simulation serial port a small program, novice understand the learning simulation serial port to see can)

使用51单片机控制LED灯，实现交通灯功能。(The use of 51 single-chip computer to control the LED lights to achieve the function of traffic lights.)

stm32单片机全功能bootloader，包括SD，串口，网口，和USB。选择条件编译(stm32 SCM fully functional bootloader, including SD, serial port, Ethernet port, and USB. Select conditional compilation)

STM3210E-EVAL官方开发板，主芯片STM32F103ZET6，支持ucLinux开发，官网也给出了开发套件。但是官网没有给出BOOT的源代码，只有HEX文件（根据推测该HEX文件时KEIL生成的）。看过UBOOT的启动后，了解了BOOT启动都干些什么事，我仿照UBOOT在KEIL软件下写功能超级简单的BOOT，就是完成外设的初始化，初始化控制器串口1，经过验证，可以跳转到内核，内核能够实现printf打印输出。(The Boot of STM32F103 uCLinux development)

该源程序是合泰46R47单片机做的热水器源程序。(The source code is Hetai 46R47 Singlechip source water heaters do.)
