CMT2300A芯片收发测程序，基于KEIL以及STM32F103芯片(CMT2300A chip transceiver and test program, based on KEIL and STM32F103 chip)

基于单片SST89V58RD2的I2C程序开发。用C语言描述的(I2C-based monolithic SST89V58RD2 program development. Described using C language)

说明：  国产ARM芯片，GD32F103系列，替代STM32F103系列，I2C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, I2C acquisition project, compile can pass, support domestic chips.)

本文件是基于51单片机的电子门铃设计程序，并且附带有proteus的仿真文件，可帮助单片机爱好者更好地学习哦！(This document is based on 51 single-chip electronic doorbell design procedure, and with proteus simulation files, can help single-chip computer enthusiasts learn better!)

动力电池保护板程序,包括主程序，IIC,定时器，ADC(Power battery protection board procedures, including the main program, IIC, timer, ADC)

温度传感器ds18b20的操作代码，直接使用。不会有任何错误(Temperature sensor DS18B20 operation code, directly used. There will be no error)

用C语言编程的PWM波在液晶屏上的显示，主控制器为单片机(C language programming of the PWM wave display on the LCD screen, the main controller for the microcontroller)
