xl系列单片机实验仪演示程序 LCD1602显示 步进电机控制器速度方向圈数可调 LCD1602显示 步进电机控制器速度方向圈数可调 K1－启动与停止步进电机运行 K2－设定步进电机运行圈数 （1-20圈） K3－设定步进电机转动方向 K4－设定步进电机运行速度 步进电机的转速控制分16档，数字越小，转速越快。 7.5度步进电机；周期7.5×4=30度，电机转动一圈需12个周期 资源：p1.0-p1.3接反向器74ls14，输出后接步进电机 p3.7接小喇叭提供按键音, p1.4-p1.7接端口按键：lcd1602插入实验仪(xl Series Singlechip Experiment LCD1602 demo program shows the direction of stepper motor speed controller circle shows the number of adjustable LCD1602 direction stepper motor controller lap speed of a few adjustable K1-start and stop the stepper motor running K2-setting step motor running a few laps (1-20 laps) K3-set stepper motor rotation direction of K4-setting speed of stepper motor stepper motor speed control minutes 16 stalls, the number of smaller, faster the speed. 7.5 degree stepper motor cycle of 7.5 × 4 = 30 degrees, rotating electric lap 12 cycles required resources: p1.0-p1.3 then reverse browser 74ls14, followed by stepper motor output p3.7 then provide a small speaker key tone, p1.4-p1.7 port access keys: lcd1602 insert Tester)

STC TQFP-44 LQFP-44封装库(TQFP-44 LQFP-44 package library)

说明：  通过定时器控制pwm输出，进而控制电机舵机的转动。(The output of PWM is controlled by a timer, and then the rotation of the motor steering gear is controlled.)

使用stm32开发板操作tcs230颜色识别模块 库函数版本 使用开发板为正点原子mini开发板(Use stm32 development board operation tcs230 color recognition module library function version uses the development board for the punctual atom mini development board)

说明：  本程序基于单片机实现RTC实时时钟，简单易懂(The program is based MCU RTC real time clock, easy to understand)

AVR单片机各寄存器的ppt整合，适用于AVR开发时查阅资料，个人整合(AVR series Microcomputer Register information)

C8051F340,CP2200,实现的串口转以太网程序(C8051F340, CP2200, implementation procedures for serial to Ethernet)

说明：  摘 要 本设计采用单片机（89S52芯片）为系统的控制核心。整个设计采用了模块化的设计思想，包括直流稳压电源模块、LED数码管显示模块、自动校零电路模块、采样电路模块、测量电路模块。( This system regards the request of the topic, adopting 80C51 for controlling core, )

说明：  单片机设计指纹密码锁，需要的可自行下载。(Single-chip design fingerprint lock, the need can be downloaded by yourself)
