AD7793驱动程序，采用IO口模拟SPI通讯的方式，方便移植到stm32单片机上，只需要更改端口定义即可。(AD7793 driver using IO port simulation SPI communication means to facilitate migration to the stm32 MCU, only you need to change the port definition can be.)

说明：  用89C51的P1口做输出口，接八只发光二极管；P3口接按钮开关，作为控制信号的输入(89C51 to do with the P1 port output, take eight light-emitting diodes P3 port access button switch, as a control signal input)

锁相环用于电机转速精准检测，资料很不错，值得下载(Phase-locked loop for accurate detection of motor speed)

stm32直流电机电机编码器 定时器编码器模式(timer encoder mode........)

说明：  使用STM32F103 32位芯片配置以及控制DC18B20传感器(Using STM32F103 32 bit chip to configure DS18B20 and control DC18B20 sensor)
