基于stm32vct6的4*4矩阵键盘扫描程序(4*4 keyboard program for stm32vct6)

基于51单片机实现倒车雷达测距系统，可直接在keil上编译生成.hex文件然后下载到单片机上运行(achieving a reversing radar ranging system based on 51 MCU,you can compile the .c file on keil software and you will get a .hex file,which should downloaded into the 51MCU and the system can operate well)

说明：  STM32单片机的库函数STM32F10x_StdPeriph_Lib_V3.5.0(STM32f103 lib STM32F10x_StdPeriph_Lib_V3.5.0)

按键控制流水灯，使用左移右移控制流水灯闪烁，实在不知道说啥了(Key control water lamp, use left shift right to control the flow of water lamp flashing, really do not know what to say)

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.)
