51单片机控制sim900a模块发短信呢，打电话，传数据的程序

MATLAB的基本知识，基本运算与函数整理(MATLAB basic knowledge, basic calculations and function finishing)

C函数查询软件，可以查询c的所有函数的和该函数的用法，并且附有例子(The C function query software, you can query all the function and the function c usage, and with examples)

这是基于51单片机的硬币电子秤的实现，内含C语言源码和proteus仿真实现 【源码目录】 硬币电子秤的实现 ├── 1Kg电子秤程序（LCD1602显示）│   ├── HX711.H│   ├── HX711.LST│   ├── HX711.OBJ│   ├── HX711.c│   ├── LCD1602.LST│   ├── LCD1602.OBJ│   ├── LCD1602.c│   ├── LCD1602.h│   ├── MAIN.H│   ├── lcd12864.LST│   ├── lcd12864.OBJ│   ├── lcd12864.c│   ├── lcd12864.h│   ├── main│   ├── main.LST│   ├── main.M51│   ├── main.OBJ│   ├── main.c│   ├── main.hex│   ├── main.lnp│   ├── main.plg│   ├── main.uvgui.Administrator│   ├── main.uvgui.Cai Chao│   ├── main.uvgui_Administrator.bak│   ├── main.uvgui_Cai Chao.bak│   ├── main.uvopt│   ├── main.uvproj│   ├── main_uvopt.bak│   ├── main_uvproj.bak│   ├── uart.LST│   ├── uart.OBJ│   ├── uart.c│   └── uart.h├── HX711模块加载文件│   └── HX711.hex├── Last Loaded 电子秤实现3.fv8.5.pdsbak├── Last Loaded 电子秤实现3.pdsbak├── 电子秤实现3.pdsprj├── 电子秤实现3.pdsprj.DESKTOP-SC10NBS.zxh.workspace└── 电子秤实现3.pdsprj.LAPTOP-KPK9NO8B.浪峰姐姐.workspace2 directories, 39 files【核心代码】void main(){    Uart_Init();    Send_Word("Weight"); Send_Word("Num"); Init_LCD1602(); LCD1602_write_com(0x80); LCD1602_write_word("Weight"); LCD1602_write_com(0x80 7); LCD1602_write_word("Num"); Delay_ms(1000); //ÑÓʱ,µÈ´ý´«¸ÐÆ÷Îȶ¨ Get_Maopi(); //³ÆëƤÖØÁ¿ while(1) { EA = 0; Get_Weight(); //³ÆÖØ Number = Weight_Shiwu/(coin_weight*10); EA = 1; Scan_Key(); //ÏÔʾµ±Ç°ÖØÁ¿ if( Flag_ERROR == 1) {            Send_Word("ERROR"); LCD1602_write_com(0x80 0x40); LCD1602_write_word("ERROR "); } else {                     Send_ASCII(Weight_Shiwu/1000 0X30);            Send_ASCII(Weight_Shiwu%1000/100 0X30);            Send_ASCII(Weight_Shiwu%100/10 0X30); Send_Word(".");            Send_ASCII(Weight_Shiwu%10 0X30);            Send_Word("g"); LCD1602_write_com(0x80 0x40); LCD1602_write_data(Weight_Shiwu/1000 0X30);            LCD1602_write_data(Weight_Shiwu%1000/100 0X30);            LCD1602_write_data(Weight_Shiwu%100/10 0X30); LCD1602_write_word(".");            LCD1602_write_data(Weight_Shiwu%10 0X30); LCD1602_write_word("g"); Send_ASCII(Number/100 0x30); Send_ASCII(Number%100/10 0x30); Send_ASCII(Number%10 0x30); LCD1602_write_com(0x80 0x40 7); LCD1602_write_data(Number/100 0x30); LCD1602_write_data(Number%100/10 0x30); LCD1602_write_data(Number%10 0x30); Send_ASCII(coin/10 0x30); Send_ASCII(coin%10 0x30); Send_Word("jiao"); LCD1602_write_com(0x80 12); LCD1602_write_data(coin/10 0x30); LCD1602_write_data(coin%10 0x30); LCD1602_write_com(0x80 0x40 12); LCD1602_write_word("jiao"); } }}

双C8051F320主从机通讯程序，可单独使用，也可双机通讯，四线协议(Dual C8051F320 master and slave communication program, can be used alone, can also be dual-machine communication, four-wire protocol)

边缘检测的各种经典算法，很值得一看。机会不容错过。快来看呀。(edge detection algorithm for the classic, is an eye-catcher. The opportunity should not be missed. Come see ah.)

自己制作 考勤机程序 已经验证成功 并有电路图(Produce their own attendance machine program and a circuit has proved to be successful)

s3c2440下的 UART程序 ADS编译 (s3c2440 under the ADS compiler s3c 2440 UART procedures of the RTC real time clock procedures ADS compiler)

说明：  国产ARM芯片，GD32F103系列，替代STM32F103系列，ADC采集项目，编译即可通过，多支持国产芯片。(Domestic ARM chip, gd32f103 series, replace STM32F103 series, ADC acquisition project, compile can pass, most support domestic chips.)
