c51 电子琴代码，调试通过。以及硬件原理图，第一次上传代码，请多多指教...

应用背景STM32可以用来接入SD卡和SPI FLASH芯片，USB Mass Storage类支持两个传输协议： 1）Bulk-Only 传输（BOT） 2）Control/Bulk/Interrupt传输（CBI） USB  驱动 关键技术开机的时候先检测SD卡和SPI FLASH是否存在，如果存在则获取其容量，并显示在LCD上面（如果不存在，则报错）。之后开始USB配置，在配置成功之后就可以在电脑上发现两个可移动磁盘。驱动USB从而读取。

用于USB 适配器的源代码，值得一看he following is a series of code files comprising the bootcode for TUSB3210.  It is already resident in on-chip ROM and therefore was not intended for our customers to compile 揳s is?and execute on the  evaluation board.  Rather, it is provided  to serve as an example of how to program the device,  and excerpts of the code can be used in real  applications (for example, the I2C subroutines).

　　Windows CE是微软为嵌入式设备打造的操作系统，而嵌入式设备可谓多种多样，这就要求CE操作系统必须是可定制的，所以微软将Windows CE设计为模块化的操作系统。说简单点，我们可以把Windows CE想像成一盒积木，你可以用积木搭建出任何物体，但不一定要把所有的积木都用上-Microsoft Windows CE for embedded devices to create the operating system, which has many embedded devices, which requires CE operating system can be customized, so Microsoft Windows CE for the modular design of the operating system. That simple point, we can imagine Windows CE into a box of building blocks, you can use the modular structures any objects, but not necessarily to put all the building blocks are used
