MCP2515 驱动，直接修改mcp2515.h里面端口即可移植使用。(MCP2515 driver, directly modify the inside ports of mcp2515.h can be transplanted.)

stm32高级定时器1产生两路相位差180度PWM，频率、占空比可调。(STM32 produces two phase difference 180 degree PWM)

说明：  51单片机驱动步进电机电路及程序 内容详细，通俗易懂，很值得(51bujindianji)

说明：  内有电路图和对应的程序，已经调试成功，能实现定时功能。(There are circuit diagrams and the corresponding procedures are debugging success, to achieve timing.)

STC12C5A60S2电子负载全部代码,TM7705做AD TM8211做DA(STC12C5A60S2,TM7705AD TM8211DA)

说明：  51单片机智能控温风扇系统，DS18B20一路测温，直流电动机控制(51 single chip microcomputer intelligent temperature control fan system, DS18B20 one-way temperature measurement, DC motor control)

MSP430实现的多级菜单功能，采用OLED实现，占用Ram量较少(MSP430 realize multi-level menu functions, the use of OLED achieved occupancy of less Ram)

基于51单片机的lcd12864液晶全屏画图程序，很有用！已通过测试！(Based on MCU 51 lcd12864 LCD full screen paint program, very useful! Has been tested!)

说明：  在编写程序时，遇到温度检测，则调用读温度软件包(In programming, temperature detection, call packages, read the temperature)

一套三相逆变器的原理图和PCB板，控制芯片为HT3117，(A three-phase inverter schematic and PCB board, controller chips for HT3117,)
