基于TMS320DM270的嵌入式开发平台的USB数据通道设计

The Designing of the USB Data Channels for the Embedded Platform Based on TMS320DM270

为TMS320DM270嵌入式系统开发平台添加了USB数据通道。首先初始化USB控制器,使PC机能够识别USB设备。然后,将开发平台上的SRAM格式化为FAT16格式的文件系统,这样在Windows的浏览器下,该SRAM就可以视作操作系统的一个RAM盘。最后,只需要执行简单的拷贝与粘贴命令,就可以实现PC机到开发平台的数据下载。这样向开发板传送数据的速度比串口明显提高。

This paper designed USB data channels for the embedded platform based on TMS320DM270.To begin with,initializing the controller of the USB in order to tag it to the PC.Secondly,formatting the SRAM in FAT16 file system,then the SRAM will be recognized as a RAM disk at the browser of the Windows PC.At last,just using the commands of copy and stick in order to realize the downloading of the data to the embedded platform.As a result,the speed of downloading data to the embedded platform can be increased evidentl...
