how to see the output for usb example in lpc54628

Karthikeyan_J — Wed, 23 Dec 2020 05:44:33 GMT

i am karthikeyan

I run the example program named USB HID Mouse application program. They said that this program will show a mouse ARROW moving on PC. I run this example in lpc54628 board, it was successfully build,clean& debug ,there was no error and warning.

But i not able to see the output in the PC , i tried with connecting a OTG cable in the USB port and with other end i connected the Mouse plug in OTG cable. I cant see the output the mouse cursor is not moving in my PC.

So my question is how to see the mouse arrow moving on the PC.

Thanking You,

Karthikeyan.

Please let me know your demo code name and version of SDK thus I will test it on my side.

There is an article, the hands on demo makes the mouse arrow moving on the PC screen in the rectangular rotation. The method is exactly the same for LPC54628

Have a nice day,

Hi,

Zhangjennie

Thanks for your reply,

Demo code name and version of SDK are

name='SDK_2.x_LPCXpress54628'

version='2.8.2'

MCUXpresso IDE v11.2.0

Example program name:dev_hid_mouse_bm and freertos too.

this was the program which i cannot get the ouput that the moving cursor on the pc.

example program description is:

The USB HID mouse application is a simple demonstration program based on the MCUXpresso SDK.It is enumerated as a mouse. Users can see the mouse arrow moving on the PC screen according in a rectangular fashion.

Thanking You,

Hi,

Zhang

I get the output.

Thank You.

can you tell me how the program is working, because i disconnected the mouse with the system but even though it still get square rotation. So my question is how the process taking place inside it(CPU & Microcontroller LPC54628[OM13098] Board.

Thanking You,

Karthikeyan

When you download dev_hid_mouse_bm to your demo board, the demo board is enumerated as a mouse. As long as you have the board connected, you will see rectangle rotation on the screen.

the output will be seen in the PC, that the mouse cursor will rotate in a square shape.
