附件程序是我用DSP2812开发的无刷直流电机控制程序，程序是在TI公司的BLDC3_1软件的基础上构造的，实现了无刷直流电机的速度环PID控制，效果可以。 其中，无刷直流电机是有HALL传感器的系统，所以在转速测量上还需要进一步的改进（如果要求精确的话）。电机是24V3000rpm～～～；驱动板是类似TI公司的DMC1500？板卡，所以可以参考它的说明（只针对信号的连接的参考）-Annex I use the procedure is the development of the DSP2812 brushless DC motor control procedures, TI is in the process of BLDC3_1 software companies on the basis of the structure, Implementation of the brushless DC motor velocity loop PID control, the effect can be. Among them, brushless DC motor are HALL sensor system So speed measurements need further improvements (if the precise words). Motor V3000rpm is 24 ~ ~ ~; Market-driven companies like TI DMC1500? Card, we can refer to it (only signal against a reference link)

应用背景stm32 驱动触摸屏程序，带校正功能，带手写功能，代码效率高，不错的驱动手写方式，关键技术开机的时候先通过24C02的数据判断触摸屏是否已经校准过，如果没有校准，则执行校准程序，校准过后再进入手写程序。如果已经校准了，就直接进入手写程序，此时可以通过按动屏幕来实现手写输入。屏幕上会有一个清空的操作区域（RST），点击这个地方就会将输入全部清除，恢复白板状态。程序会设置一个强制校准，就是通过按KEY0来实现，只要按下KEY0就会进入强制校准程序。

SST flash driver,已经经过测试，无需修改源码，只需根据不同平台调整延时即可。

无线下载更新程序功能，在zigbee的应用中非常有用，现在的厂商包括TI freescale等厂商号称可以但都未提供该功能或者该功能还很不成熟，上传的是基于5139芯片的无线下载更新功能程序，非常实用。-Wireless download the update feature in zigbee application is very useful, and now manufacturers and other vendors, including TI freescale claims may, but failed to provide the feature or the feature is still immature, the upload is based on the 5139 chip wireless download the update feature program, very useful.
