Other Parts Discussed in Thread: LAUNCHXL-F28069M

您好,我在使用CCS9.0调试官方例程 usb_dev_bulk,例程路径是C2000》device-support》F2806X 》examples》C28》usb_dev_bulk,根据suasn yang回复的步骤运行LAUNCHXL-F28069M的usb_dev_bulk例程,到第6步时,输入字符串,电脑上的CCS Terminal窗口没有反应,COM口什么也没有,怎么解决这个问题呢?

以下是suasn yang的回复;

以28377开发板为例,下面是详细的步骤

The "usb_dev_bulk" example provides a generic USB device offering simple bulk data transfer to and from the host. The device uses a vendor-specific class ID and supports a single bulk IN endpoint and a single bulk OUT endpoint. Data received from the host is assumed to be ASCII text and it is echoed back with the case of all alphabetic characters swapped.

Follow the following steps to run the example

1 Load the binary and run the example.
2 Connect the USB Cable from your PC to the USB Micro Slot in the Control Card on top.
3 Open a Serial Terminal with the settings 115200 Baud 8-N-1 for the XDS 110. It will show if the device is connected or disconnected.
4 Copy the tiusbdll.dll from the {Latest C2000Ware Package}/utilities/tools/f2837xd/tiusbdll/Release folder to "usb_bulk_example" application project folder
5 Open the windows application ""usb_bulk_example" in {Latest C2000Ware Package}/utilities/tools/f2837xd/usb_bulk_example.
6 Enter a string which will be the bulk data sent and the XDS 110 Com Port will print the length of the string sent.

运行结果如下所示;
