RINGCOUNTER

用于可见光通信的发射和接受端的程序，使用曼彻斯特编码(Program for transmitting and receiving ends for visible light communication, using Manchester coding)

说明：  使用STM32单片机开发的简易电子钟，并实现计时报时(A Simple Electronic Clock Developed with STM32 Single Chip Microcomputer)

在IAR Embedded Workbench IDE平台使用ATmega1280的USART0口的编译连接通过的自编程程序(In the IAR Embedded Workbench IDE platform USART0 the ATmega1280 compiler I connect through the process of self-programming)

一个比较典型的PID处理程序，在使用单片机作为控制cpu时，请稍作简化，具体的PID 参数必须由具体对象通过实验确定(A more typical PID treatment procedures, the use of single-chip microcomputer as the control cpu, please make some simplification, the specific PID parameters must be determined through experiments at specific audiences)

说明：  SLICON LABS 公司ISM 无线收发芯片 IA4320 设计无线键盘的电路图，源代码，使用手册 无线射频注意事项。(SLICON LABS' s ISM wireless transceiver chip IA4320 designed wireless keyboard circuit, source code, manuals RF considerations.)

CC2530,通过PWM调光，实现LED灯由亮变暗，由暗变亮，不断变化，基于IAR编译。(CC2530, by PWM dimming, LED lights achieve the light dimmed by the dark to light, constantly changing, based on the IAR compiler.)

基于Proteus环境进行8086 CPU汇编语言程序设计的源代码，包含经典的红绿灯控制，循环与分支程序设计(Based on Proteus environment 8086 CPU assembly language programming source code, including the classic traffic light control, circulation and branching program design)

使用数码管和AT24C02实现： 1、数码管从0显示到99，溢出后从0循环显示，时间间隔为一秒。 2、显示到某个数时突然关闭电源，AT24C02将保存当前的数字。 3、重新启动后数码管会接着上次的数继续显示(Using digital tube and AT24C02 implementation: 1, the digital tube displays from 0 to 99. After overflow, it displays from 0 cycles, with a time interval of one second. 2, display a number of time to turn off the power suddenly, AT24C02 will save the current number. 3, after reboot, the number will continue to display.)

1.基于STM32利用DRV871驱动步进电机 2.配置SPI使STM32和DRV871通信控制步进电机 3.配置PWM控制DRV871的Step来控制步进电机的转速(1. using DRV871 to drive the stepper motor based on STM32 2. configuration SPI makes STM32 and DRV871 communication control step motor 3. configuration PWM controls the Step of DRV871 to control the speed of the stepper motor)

关于交通灯的单片机课程设计，内含程序代码以及Proteus的使用资料。(Information on traffic lights using microcontroller curriculum design, including the program' s code, and Proteus.)
