Description: 首先要说：是我自己写的你他地方下不到！
这是一个用PWM播放.wav歌曲文件的程序，歌曲本身已经被和代码一起固化到FLASH中了，想要听到美妙的歌曲你只需要把PB0经过一个滤波放大电路接到蜂鸣器或耳机插孔上，并把程序下到你的STM32中运行就可以了。
另外，看看这篇关于PWM播放.wav的文章：http://wmx0901.blog.163.com/blog/static/10320222020097171727367/edit/-First of all, to say: I wrote it myself, he places less than you! This is a PWM player with. Wav files songs, songs and the code itself has been with the curing of the FLASH, and you want to hear the wonderful songs you have to do to go through a filtering PB0 received buzzer amplifier or headphones jack, and the procedures to run your STM32 it. In addition, take a look at this on the PWM player. Wav article: http://wmx0901.blog.163.com/blog/static/10320222020097171727367/edit/

Description: 此程序是基于STM32的AD应用程序，我们在这里设置ADC为连续转换模式，常规转换序列中有两路转换通道，分别是ADC_CH10(PC0)和ADC_CH16(片内温度传感器)。因为使用了自动多通道转换，数据的取出工作最适合使用DMA方式取出，so，我们在内存里开辟了一个u16 AD_Value[2]数组，并设置了相应的DMA模块，使ADC在每个通道转换结束后启动DMA传输，其缓冲区数据量为2个HalfWord，使两路通道的转换结果自动的分别落到AD_Value[0]和AD_Value[1]中。
然后，在主函数里，就无需手动启动AD转换，等待转换结束，再取结果了。我们可以在主函数里随时取AD_Value中的数值，那里永远都是最新的AD转换结果。
如果我们定义一个更大的AD_Value数组，并调整DMA的传输数据量（BufferSize）可以实现AD结果的循环队列存储，从而可以进行各种数字滤波算法。-This program is based on the STM32 processor AD debugging applications, we are here to set the ADC for continuous conversion mode, conventional two-way conversion sequence are converted channels, respectively ADC_CH10 (PC0) and ADC_CH16 (on-chip temperature sensors). Since the use of an automatic multi-channel conversion, data, work out the most appropriate way to use DMA out, so, we have opened up in memory of a u16 AD_Value [2] array, and set the corresponding DMA module, so that each channel ADC conversion After the start the DMA transfer, the buffer data for the two HalfWord, so that the conversion results of two-way channels were automatically fall AD_Value [0], and AD_Value [1] in the.
Then, in the main function, where is no need to manually start the AD conversion, to wait for the end of conversion, and then take the result. We can readily accessible in the main function where the value of AD_Value, there is always the latest AD conversion results.
If we define a larger arra

Description: 在STM32的I2C上摔了一跤，测试了官方提供的几个例程和库，都有不同缺陷，也无法弥补：
1、查询方式，在连续读数据的过程中不能中断
2、DMA方式类似，在同一DMA中I2C的级别必须最高，否则同1.
3、中断方式也不能有更高优先级中断I2C，否则同1.
鉴于以上原因，无奈的口线模拟了I2C。（仅仅代表个人看法，欢迎指正）
附件中的项目文件已经过测试，为感谢OUR这几年的帮助，先开源这个小程序-I2C on the STM32' s fall, the official offered few tested routines and libraries, have different defects, can not make up: 1, query methods, in a continuous process of reading the data can not be interrupted 2, DMA similar to at the same level of DMA in the I2C to be the highest, or with 1.3, can not interrupt higher priority interrupt I2C, or with 1. For these reasons, but unfortunately the port line to simulate the I2C. (Only represent my personal views, please correct me) the attached project document has been tested and OUR for the past few years thanks to help, first open the applet
