自己做的双柄遥控板，内含完整工程代码。使用的是OLED显示方案，带中文字库，不会添加的可以学习里面的代码。带显示界面，整理文档按照原子哥风格。文件里还有其他芯片的工程代码和驱动（其他工程的 都放在HARDWARE里没删掉）

在dma下触发dac 产生正弦波，可以节省时间 并且精度高 程序更加简洁明了

STM32上12864上显示二维码的显示,完整工程（保护原理图），本产品是属于个人开发的一个案例经过实践但是目前未上市，所以如果你完全按本工程操作的化，理应能够实现其功能，另外本工程中包含里语音KT404A串口语音驱动芯片的实现，FIFO消息队列缓冲的实现，串口操作部分采用USART-DMA的实现.

本例程主要是用于两块stm32之间的spi通信，用到了ＤＭＡ节省了ｃｐｕ的的时间，大大提高了ｃｐｕ的利用率

参考论坛的一下文档，写了这个STM32串口DMA收发程序，里面有详细注释，方便查看。

一个简单的verilog编写的DMA IP CORE，和大家分享一下 绝对值得下载

stm32f103进行同步规则进行转换，其中代码做了比较详细的注释，对于同步规则中的参数进行了实验，欢迎大家指正。

STM32F407ADC采集信号通过DMA发送给内存，并且通过串口发出，已调试通过
