Segger 的 emWin emWin v5.24c 同 Micrium 的　uC/GUI v5.24c。内附应用代码 / 应用例程 / 应用工具及 pdf 说名文件等，是当前 GUI 的第一首选，易上手使用！ (Segger emWin emWin v5.24c uC same Micrium uC/GUI v5.24c. Containing application code/routines/application tools and PDF documents, is the first choice for the current this GUI, and approachable to use!)

4*4键盘程序，可以用来应用到各种电子单片机上直接加入(4*4 KEY PROGRAM)

说明：  通过89c51单片机来控制两轮小车的运动程序，简单易学(Through 89C51 MCU to control two wheeled vehicle's motion program, it is easy to learn.)

Lecture notes on Functions in C++ with Examples

用51单片机读写温度传感器ds18b20温度源码包含温度传感器初始化及温度读写等功能。(Program for reading and writing tempreture sensor DS18b20. )

利用GPIO控制无源蜂鸣器发声，播放音乐。使用SysTick延时，使用位带操作寻址IO口引脚。(GPIO is used to control the voice of passive buzzer and play music. Use SysTick delay, use bit band operation to address IO pins.)

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)
