基于st的m3单片机STM32f103 矢量控制 驱动交流异步电机的源程序(St m3 SCM STM32f103 vector control drive of the source of the AC induction motor)

自主学习PIC芯片，此书主要讲PIC16F877(Self-learning PIC chip, this book mainly talks about PIC16F877)

项目16 基于单片机LCD数字测速仪的设计 使用C++程序编程(Item 16 LCD digital speedometer on chip design using C++ programming)

MCU图片解码，使用STM32对JPEG图片解码，(STM32 JPEG decoder code,)

采用51系列单片机为控制核心，包括电源变换处理及分配模块，恒流源模块，单片机主控模块，键盘输入模块，LCD显示模块，数模/模数转换模块，语音模块和实时时钟模块的9个部分。通过键盘设定好需要输出的电流值后，单片机对设定值按照一定的算法进行处理，经数模输出电压控制恒流源电路输出相应的电流值(51 Series single-chip microcomputer used for the control of the core, including the processing and distribution of power transform module, constant current source module, single-chip control module, the keyboard input module, LCD display module, digital-to-analog/analog-digital conversion module, voice module and real-time Clock Module Part 9. Through the keyboard need to set output current value, single-chip microcomputer according to the settings of the algorithm processing, digital-to-analog output voltage by the control constant current source circuit output current value of the corresponding)

说明：  STM32控制DDS输出正弦波等波形，频率幅值可调。(STM32 control DDS output sine wave waveform, adjustable frequency amplitude.)

工业中实时温度曲线显示仿真程序，采用了第三方控件，提出来大家一起研究。(tempratrue)

电子爱好者们经常希望测试自己的音频设备如声卡、碟机、功放、音箱等的性能指标，却苦于没有价格高昂的专业测试设备而无从下手，设计制作时也无法进行必要的测试指导。有些CD碟提供了测试信号，如著名的“雨果发烧碟（一）”、“My Disk”等，《无线电》也曾推出音频测试CD。但CD信号的精度有限，而且没有操作系统的配合，测量、记录和分析都很不方便。(Electronic fans often want to test their audio devices such as sound cards, CD, amplifier, speakers and other performance indicators, but have no specialized test equipment without the high price the start, can not carry out the necessary tests to guide the design of production. Some CD discs provide a test signal, such as the famous Hugo Audiophile CD (a) , My Disk and so on, Radio has launched an audio test CD. CD signal but the accuracy is limited, and there is no tie, measurement, recording and analysis of the operating system is very inconvenient.)

1.可以自动生成十六进制字编码。 2.可以自动C语言格式字符编码。 3.支持GBK和ASCII字符编码查询。(1 can automatically generate a hexadecimal character encoding. 2 can automatically format the C language character encoding. 3 support GBK and ASCII character encoding query.撤消修改)
