Hello,

I have microcontroller LPC5512JBD100E on my board, I have to check if the USB cable is connected with the board, and to have feedback from the controller about that. Which software do I need to have and how to do it ?

Best regards,

Milan

Hi,

As you know that the LPC5512 has one full-speed USB, which can function as both device and host.

We provide USB stack in SDK package, you can download SDK package from the link:

https://www.nxp.com/design/software/development-software/mcuxpresso-software-and-tools-/mcuxpresso-s...

You can select the USB class example in SDK USB example for example CDC, MSC...

From hardware perspective, when the USB of LPC5512 functions as a device, when a USB cable is inserted, an USB interrupt will be fired on LPC5512 side, the host can communicate with the device and exchange the descriptor inf.

Hope it can help you
