USB HID Stm32f767

Hello,

I've built a project with an STM32F767 and a USB HID connection. I also have a Visual Studio 2010 application to set PA0 to 1 for testing. My connection is established, and in Device Manager, the USB Custom HID device is recognized, but I can't set PA0 to 1. I built my USB HID code using Cube MX and the HidLibrary.dll driver for VB2010. I don't understand why I'm having this problem. Can anyone help?

I am able to get a result, temperature acquisition and change of state of PA0 in CDC mode.

Best regards.

My code is attached.

Sébastien.

    Hello @PSEBA.1,

    After reviewing your application, it appears that you are missing the configuration for the CUSTOM_HID_OutEvent function. Currently, there is no process implemented to handle the data sent from the host to set PA0 to 1.

    I recommend referring to the article "How to implement a USB device custom HID class on STM32" , which provides detailed instructions on configuring the custom HID class, including handling the OutEvent for receiving data from the host.
