ds18b20 驱动程序，可方便移植多个平台。(ds18b20 driver.)

STC51单片机GPIO口模拟串口，实现包含UART、SPI、IIC等(STC51 microcontroller GPIO port simulation serial port and realize UART, SPI, IIC, etc )

该代码为本人的本科毕业设计代码，由于电路原理图丢失，不能提供原理图，但代码类每一个外设模块都有引脚的接口说明，代码也有详细的说明，代码风格与官方风格相似，本人在开发时比较注重代码的可读性，该设计是基于手机蓝牙和stm32单片机的一款RGB-LED变色变光远程+近程控制的智能灯，该代码仅提供参考，不可作为商业用途，若作为商业用途，产生的不良后果自行承担，在此声明！本人为初学者，代码仅供参考！(The code for my graduate design code, the circuit principle diagram is lost, can not provide the principle diagram, but the code class each peripheral module has pin interface that the code is described in detail, and the official code style is similar in style, I pay more attention to the readability of the code in the development, the design is intelligent variable light remote control + mobile phone Bluetooth and STM32 MCU RGB-LED a color based on the code for reference only, not for commercial purposes, if used for commercial purposes, adverse consequences borne, in this statement! I am a beginner, the code is for reference only!)

红外摇控(HT6221)控制小车,用51单片机编写的(Infrared remote control (HT6221) to control the car, written in 51 single chip microcomputer )

AT89C51制作的电子琴，有16键，还有自动播放音乐演奏功能(AT89C51 making organ, 16 keys, music player function also automatically)

不错的拓普微3.5寸LCD显示屏驱动代码，可以参考(Good TOPWAY 3.5-inch LCD display driver code, you can refer to it)
