C语言写的DMX512灯光控制源程序，实测通过

UART：通用

应用背景公司因项目需要，购买悠景的OLED显示屏，驱动芯片为SSD1306，需要编写驱动程序，后来通过规格书，使用I2C方式，驱动成功，并成功应用，相关也参考了些网上的其他驱动。关键技术SSD1306 本驱动使用I2C驱动方式，此方式减少了单片机IO口的占用，极为简便，方便使用。  依单片机内存大小调整显示缓存，如果单片机内存比较小，则应改小显示缓存。

这是 STM32F 标准驱动程序源 codeFor EWARM。一些由自己修改的代码。

Hot-pluggable device is now a big threat to IT security. In this article, we will try to develop a user-mode application to detect device change on the system, i.e. plug-in a USB drive, iPod, USB wireless network card, etc. The program can also disable any newly plugged devices. We will get a basic idea on how this works and talk about its limitations at the end of this article.

这是花了三天时间调试的代码。解压在D盘，用ccs5打开进行编译。ram运行方式，方便反复调试，减小程序debug时下载时间。对dsp的spi通讯调试非常详细有用。dsp使用内部时钟初始化。spia作主站，spib做从站。单dsp做主从站的程序。简单配置后，可以在DSP的双spi的芯片上运行。已经在TMS320F28069上调试成功。芯片连接时，需要四根通讯线路一一对应的连接。断点位置可以放在★的位置，查看收发的数据。spistea，spiteb是通过寄存器赋值实现的。
