ARM Cortex M-3 1700系列微处理器在Keil uvision4 下对I2C的编程实例(ARM Cortex M-3 1700 microprocessors under the Keil uvision4 programming examples for I2C )

单片机串口通信,收发数据缓冲区示例,在中断中不处理接收的数据,只是按循环队的方式将数据存起来,标示Buf中有多少个数据,在主程序中去查询.(Microcontroller serial communication, send and receive data buffer example, in the interrupt does not handle the data received, but on a revolving team approach to store data together, marked Buf how many items of data, in the main program to query.)

用Stm32f103当示波器，具有分析输入波形功能，同时又能输出波形自己花了将近一个月编出。(When using Stm32f103 oscilloscope, with analysis of the input waveform function, at the same time can output waveform spent nearly a month to write themselves.)

说明：  采用89C51+DS1820+数码管+蜂鸣器DS1820设置为12位精度，环境温度超过Alarm值 蜂鸣器报警，超过40度 继电器启动 ，Alarm值可通过按键自由设定 (With 89C51+ DS1820+ DS1820 digital control+ buzzer set to 12-bit accuracy over temperature buzzer alarm Alarm value, more than 40 degrees relay start, Alarm value can be set freely by key)

说明：  STM32F103RB模板，基于官方固件库3.5(STM32F103RB template, based on official firmware library 3.5)

STM32开发手册，挺好用的，希望能够帮助你，还望多多交流，相互学习(STM32 development manual, very good use, hoping to help you, but also look more exchanges, learn each other)

说明：  用于数字信号的联合差分解调程序，主要用于GMSK调制信号(Joint differential for digital signal demodulation process, mainly for GMSK modulated signals)

说明：  ADI测试代码，ADI官方开发板测试demo分享(ADI ADSP21479 POST and the demo)

ARM指令系统和体系结构的学习PPT，对初学者非常有帮助(ARM instruction set and architecture of learning PPT, very helpful for beginners)

说明：  STM32的PWM输出模式，STM32的TIM1模块是增强型的定时器模块，天生就是为电机控制而生，可以产生3组6路PWM，同时每组2路PWM为互补，并可以带有死区，可以用来驱动H桥。(STM32' s PWM output mode, STM32' s TIM1 module is enhanced timer module, is inherently for the motor control, it can produce three groups 6-channel PWM, while the complementary PWM each 2-way, and can be with the dead zone, can be used to drive H-bridge.)
