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: 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

Description: STM32作为主控芯片，72Mhz，利用DMA+PWM实现驱动WS2812，创建16个并行800kBit / s数据流的想法如下：
使用定时器每1.25us创建一个800kHz的时基和一个DMA请求。
使用2个比较模块在低位时间（350ns）和高位时间（700ns）下创建DMA请求
1.25us DMA请求将GPIO端口的所有位设置为高电平
350ns DMA请求将数据从帧缓冲区传输到GPIO端口。如果该位为0，GPIO引脚将变为低电平，否则将保持高电平。
700ns DMA请求将所有GPIO引脚设置为低电平。
重复步骤1到3，直到发送所有位。
这产生脉冲周期为1.25us，脉冲宽度为350ns或700ns的脉冲流，具体取决于脉冲表示的位值，通过DMA将数据传输到GPIO端口意味着每16个LED每位需要一个字（两个字节）。每个LED 24位，每16个LED 24个字（48个字节）。(The idea to create 16 parallel 800kBit/s data streams is the following:
Use a Timer to create an 800kHz time base and a DMA request every 1.25us.
Use 2 compare modules to create DMA requests at the low bit time (350ns) and the high bit time (700ns)
The 1.25us DMA request sets all bits of the GPIO port high
The 350ns DMA request transfers the data from the frame buffer to the GPIO port. If the bit is a 0, the GPIO pin will go low, otherwise it will stay high.
The 700ns DMA request sets all GPIO pins low.
Repeat steps 1 to 3 until all bits have been transmitted.
This creates a stream of pulses with a pulse period of 1.25us and a pulse width of either 350ns or 700ns depending on the bit value the pulse represents.
Transferring the data via DMA to the GPIO port means that per 16 LEDs one half word (two bytes) is needed per bit. At 24 bits per LED that makes 24 half words (48 bytes) per 16 LEDs.)
