说明：  基于STC51单片机使用UART串口模块通讯例子(STC51 using UART serial port module communication example)

pt100高精度测量电路，精度误差小，速度快，arm9 c51均可实现 ，仅供学习 参考(PT100 high precision measurement circuit, precision error is small, fast, C51 ARM9 can be achieved, only for learning reference )

1、proteus 仿真 1602 与IIC总线形式的EEPROM 2、内含KEIL 工程源文件（C语言） 3、内含proteus 源文件 (Proteus simulation 1602 form IIC bus EEPROM contains the KEIL engineering source files (C language) 3, containing proteus source file)

基于8051单片机的USB软件狗的原理图及PCB(Based on 8051 USB dongle schematic and PCB)

液晶1602单片机驱动程序代码，适合stc89c52rc,at89s52.(The driver code of 1602 display,for mcu stc89c52rc,at89s52.)

51单片机采集18B20温度数据发送到蓝牙模块(Send 51 SCM Acquisition 18B20 temperature data to the Bluetooth module)

基于STM32的三相带霍尔的无刷电机控制源码，功率控制，转速pid调节，过压欠压保护，过流保护，等(STM32-based three-phase brushless motor with Hall of source control, power control, speed pid regulation, over-voltage protection, overcurrent protection, etc.)

说明：  此应用笔记收集了用软件实现的主模式SPI程序。提供了8 个不同的SPI 主模式传输例。示例中包含SPI时钟相位和极性两个子例程：一个是用C 语言编写的例程，一个是为了提高速度用汇编语言编写的可被C 语言调用的例程。一个例子是在“C”程序中如何调用汇编同时提供了EEPROM接口例子。SPI是摩托罗拉商标。 此文档中描述的SPI功能使SPI处理的软件 最小化。在系统中使用C8051F30X 器件作为 总线上的SPI 主器件。(This application note collection implemented in software SPI master mode procedures. Provides 8 different SPI master mode transfer cases. Examples include SPI clock phase and polarity of the two sub-routines: one is written in C language routines, one is to increase the speed of assembly language written in C language can be called routine. One example is in the &quot C&quot programs how to call assembly also provides examples of EEPROM Interface. SPI is a Motorola trademark. SPI described in this document processing software capabilities to minimize the SPI. In the system C8051F30X SPI device as the primary device on the bus.)

使用STM8配置TIME1、UART1、UART3，在STM8S007单片机控制使用空气温湿度传感器（SHT10）、温度传感器（DS18B20）(Using STM8 configuration, TIME1, UART1 and UART3, the STM8S007 microcontroller controls the use of air temperature and humidity sensors (SHT10) and temperature sensors (DS18B20))

利用stm32输出pwm波，希望能给大家带来一些帮助(Output PWM wave by stm32)
