基于STM32F407的超声波模块测距，增量式编码器（1/30减速比）实时测速，PWM输出控制直流单机，并通过OLED显示实时数据，同时也通过串口打印(Based on STM32F407 ultrasonic module ranging, incremental encoder (1/30 deceleration ratio) real-time speed measurement, PWM output control DC single machine, and display real-time data through OLED, but also through serial port printing.)

AD7991采集数据程序，C语言编程，keil软件，可实现三通道轮流采集，程序中添加串口显示返回值，亲测，可用(AD7991 data collection procedures, C programming language, keil software, can achieve a three channel samples in turn, add serial program to display the return value, pro test available.)
