I2C

利用ATMEGA32设计的温控表，具有通过RS232接口与上位机通讯的功能，设定目标温度后程序通过设定的PID值进行温控，使得温度快速接近设定值。(Use the ATMEGA32 design temperature controller, PID values ​ ​ set temperature control via RS232 interface with PC communication function, set the target temperature program, rapid temperature close to the set value.)

说明：  带接收和发送协议处理的串口调试工具，可只接收并显示自定义关键字的串口数据，非常好用，带这种功能的可用的此类软件不多，值得收藏。(ComFilter,can receive and display your expired information from COM.)

常用算法程序集（C语言描述） （第三版）源代码(commonly used algorithm C code)

12864串口液晶,包含两个文件:lcd.c与lcd.h. 调用 void printLCD(uint8 x,uint8 y,uint8 *fmt, ... ),即可将显示的字符串发送到液晶屏显示(12864 Serial LCD, contains two documents: lcd.c with lcd.h. call void printLCD (uint8 x, uint8 y, uint8* fmt, ...), can be shown in the string sent to the LCD screen display)

本代码是基于标准c8051单片机的时钟打铃程序，主要实现的是数字时钟功能，可对时间进行调整，设定时间定时打铃，并且能随自己意愿调整铃声。(This code is based on the standard c8051 MCU clock bell program, the main achievement is the digital clock feature, which allows time to adjust, set the timer bell time, and can adjust the ring with their wishes.)
