51单片机led流水灯例程，利用查表法显示8个led流水灯效果(51 single led light water routine, use a lookup table to display 8 led light water effects)

1.东西方向、南北方向均有红、黄、绿三种信号灯； 2.东西干道和南北干道，绿灯下情况通行，红灯情况下不行，黄灯情况下 慢行； 3.东西干道和南北干道交替控制； 4.实时提醒绿灯亮的剩余时间； 5.通行时间可调； 6.雾霾或夜间模式按钮按下，所有方向显示黄灯.(1. there are three red, yellow and green lights in east-west direction and north-south direction. 2. the East West trunk road and the north-south trunk road pass under the green light. 3. East and west main road and the north and South Main Road alternately control; 4. reminding the remaining time of the green light in real time; 5. the time can be adjusted; 6. haze or night mode button is pressed, all directions show yellow light.)

内有PID源码驱动，包含位置式PID和增量式PID。PID通过结构体定义，可同时定义多套参数，并同时使用，并不会相互影响。(There is a PID source driver, including position PID and incremental PID.PID through the structure definition, can be defined at the same time multiple sets of parameters, and use at the same time, will not affect each other.)

STM32 USB IAP（STM32 DFU），STM32F10X usb升级程序的程序，以及测试程序，还包括dfuse安装软件和使用说明。在刚开始进行stm32 usb升级程序的过程中，网络的很多资料都不完整，错误的很多，自己也遇到了一些问题，话费不少时间，在成功完成此功能后感觉很有必要分享出来，减少大家开发stm32 usb iap功能的时间。(STM32 USB IAP（STM32 DFU）and test program)

七段数码管的显示驱动程序.分查表法和跳转法.采用松翰8位单片机汇编语言编写的子程序, 本人验证过.(seven_segment_tube_display.asm assembly with Sonix 8bit IC)

说明：  51单片机串口控制继电器的C源程序，用电脑控制继电器(51 MCU C source control relay)

STM32F407 MPR121键盘模块驱动，可以实现12个触摸点并且读出键值(STM32F407 MPR121 driver)

STC15F104W单片机虚拟串口，并且带有18B20测温的功能，可与MCU或上位机进行通讯，波特率可以在程序中设置，带有队列，工作稳定(STC15F104W microcontroller virtual serial port, and with 18B20 temperature function can be used with MCU or PC communication, baud rate can be set in the program, with a queue, stable)

采用STM32F429单片机连接摄像头采集图像，并附源码(STM32F429 MCU is used to connect camera to collect image, and source code is attached.)
