STC系列单片机各功能模块驱动代码，如UART，I2C,SPI, ADC, I/O,TIMER, PWM等(STC MCU Drive function, such as UART, I2C,SPI, ADC, I/O,TIMER, PWM and so on)

只能小车寻线与避障加寻光51单片机代码，就是全国电子设计竞赛1999年的E题啦。(Only the car line code 51 single-chip microcomputer and obstacle avoidance for light)

ESP8266，实现无线通信模块的传输,通过51单片机(ESP8266, realizing the transmission of wireless communication module)

dspic30f4011单片机按键控制LED与UART通信(dspic30f4011 microcontroller buttons to control the LED and UART communication)

说明：  由于不满意语音芯片的复制性差，于是自己做了一个语言模块，用STC12LE2052单片机的PWM功能播放声音，从Wave文件中提取的声音数据通过串口从计算机下载，存储在串行Flash芯片SST25VF016B中，可进行单段播放和循环播放，单个模块的制作成本应该在30元以下，可以播8K8位的声音256秒。(Not satisfied with the voice chip, as a result of poor copy, so do a language module, with the STC' s 2052 single-chip PWM function to play a sound, from the Wave files to extract the audio data downloaded from the computer through the serial port, is stored in the Serial Flash chip, can play single player and recycling, the production costs of a single module should be below 30, you can broadcast the voice of 8K8-bit 256 seconds.)

基础的51单片机开发程序，适合学习单片机C语言开发的初学者，关于十进制、十六进制、二进制数之间转换的程序。(basic c language program for new 8051 mcu developers ,suitable for new learners of muc c language developers,about nuber cardinal convertion of decimals,hex and binary.)

本程序利用系统节拍定时器生成测试脉冲，利用定时器捕获功能来计算脉冲的宽度和占空比。(The program uses the system tick timer to generate test pulses, using a timer capture function to calculate the pulse width and duty cycle.)

说明：  串口调试助手，可显示波形，图像GPS定位，智能车助手(Serial debugging assistant, waveform display, image GPS positioning, intelligent car assistant)

使用MSP430 控制器作为主机的，对bq27210器件配置和通信的例程。提供IAR和CCS两种开发环境的工程文件。(MSP430 is used as the host microcontroller interfacing to various bbq27210 devices.The complete source code and project files have been provided for the two embedded firmware Integrated Development Environments for the MSP430 microcontroller platform – IAR Systems Embedded Workbench and Texas Instruments Code Composer Studio.)
