一个完整的SVPWM程序，编译通过；基于28335(A complete SVPWM procedures, compiled through based on 28,335)

基于STM32F407ZET6，软硬件SPI协议读写W25Q128FLASH模块(W25Q128FLASH module read and write based on STM32F407ZET6, software and hardware SPI protocol)

说明：  基于stm32单片机电压表设计,AD检测分压电阻电压值，根据电阻分压比算出所测电压，并显示在oled液晶上(Based on the design of voltage meter of STM32 single chip computer, AD detects the voltage value of dividing resistor, calculates the measured voltage according to the ratio of dividing resistor voltage, and displays it on OLED liquid crystal.)

韩国单片机ABOV的头文件 此单片机价格比较便宜(South Korea' s single-chip microcontroller ABOV the header of this relatively cheap price)

一种应用于飞思卡尔9s12系列的AD转换模块程序范例(An example of the AD convert program applied in the Freescale 9s12 series.)

通过温度的变化来改变电子时钟的时间值，可以随时感应当前的温度，并且可以手动设置时间及闹钟、延迟等各种功能(To change the time value of the electronic clock by a change in temperature, and various functions can manually set the time and alarm, delay can always induced current temperature,)

说明：  STM32F103实现BLDC调速，此代码可以实现BLC和PMSM开环的控制(STM32F103 realizes BLDC speed regulation. This code can realize open-loop control of BLC and PMSM.)

说明：  0.2通道180°相位差方波，3通道120°相位差方波，4通道90°相位差方波 1.试验平台stm32f103c8t6 2.2通道用定时器3的1、2通道；3通道用定时器3的1、2、3通道；4通道用定时器3的1、2、3、4通道； 3.实现方法，周期和占空比用捕获通道中断反复修改捕获值来实现 4.相位差采用定时器的生效同步规则来实现（下一次更新时间生效）(0.2 channel 180 degree phase difference square wave, 3 channel 120 degree phase difference square wave and 4 channel 90 degree phase difference square wave 1. Test platform stm32f103c8t6 2.2 channels use 1, 2 channels of timer 3; 3 channels use 1, 2, 3 channels of timer 3; 4 channels use 1, 2, 3, 4 channels of timer 3; 3. Realization method, period and duty cycle are realized by repeatedly modifying capture value with capture channel interrupt 4. The phase difference is realized by the effective synchronization rule of the timer (the next update time takes effect))
