对lcd1602屏的一些常见问题作出解释，并附上一段51单片机驱动lcd1602代码(Explain some common problems of LCD 1602 screen, and attach a section of LCD 1602 code driven by 51 single chip computer.)

硬件资源: 1,DS0(连接在PA8)，DS1(连接在PD2上) 2,串口1(波特率:115200,PA9/PA10连接在板载USB转串口芯片CH340上面) 3,ALIENTEK 2.8/3.5/4.3寸LCD模块(仅支持MCU屏) 4,按键KEY0(PC5)/KEY1(PA15)/KEY_UP(PA0,也称之为WK_UP) 实验现象: 按下KEY_UP键申请内存，内存申请成功以后就可以使用了，按下KEY0键 就是使用申请到的内存。当内存使用完成以后就可以按KEY1键将内存 释放掉。(Hardware resources: 1, DS0 (connected to PA8), DS1 (connected to PD2) 2. Serial port 1 (baud rate: 115200, PA9/PA10 connected on board USB to serial chip CH340) 3, ALIENTEK 2.8/3.5/4.3 inch LCD module (only supporting MCU screen) 4. Keyboard KEY0 (PC5)/KEY1 (PA15)/KEY_UP (PA0, also known as WK_UP) Experimental phenomena: Press KEY_UP key to apply for memory, memory application can be used after success, press KEY0 key That is to use the applied memory. When the use of memory is complete, you can press KEY1 to store the memory. Release.)

RC500的程序源码原理图 具有读写功能 串口通讯等功能(RC500 with the program source code to read and write functions schematic features such as serial communication)

STM32 的GPIO操作示例程序代码, 试用与Keile环境STM32F103代码(STM32 GPIO operation code)

说明：  c8051f020图片显示 不复杂 可以自己变换图片 第一次写这类的 不太好大家指出(the c8051f020 picture display pictures online to find the program)

ESP8266制作的安卓控制电风扇，内含详细电路即软件。手机APP使用非常简单。智能家居等设备控制均可类似实现(ESP8266 Android-controlled fan, fan after simple modification can be realized, containing detailed circuit software.Mobile APP is very simple.Smart home control can be similar to achieve)

PSCAD仿真程序，Buck降压电路，有PI控制，很有参考价值(PSACD program,Buck Chopper)

51单片机的智能交通灯系统的源代码，可以用键盘更改交通灯的时间(51 single intelligent traffic lights system source code, you can use the keyboard to change the time of traffic lights)

说明：  利用STM32F106RET6的串口1发送字节或数据(STM32F106 com comunication)
