Hello.

I found the USB HID Demonstrator application. I want to test it with my STM32F4 Discovery board. But i don't have any code in the microcontroller to communicate with this application. Can anyone help me to find the code.

Thank you.

Perhaps you can review the USB firmware libraries

STM32_USB-Host-Device_Lib_V2.1.0\Project\USB_Device_Examples\HID

STM32_USB-FS-Device_Lib_V4.0.0\Projects\Custom_HID

For the STM32F4-Discovery board you will likely need to port the code as they typically target the more expensive EVAL series boards.

Thank you clive1. But i don't know what is the difference between the targets and mine to make the correct modifications.

Mainly the LCD panel, and hardwired connectors, you'll need to review the pin assignments, schematics and code. You'll need to do your own due diligence, as this isn't my project.

 allow to the microcontroller to communicate with the USB HID application. But some features don't work. I want to control the trimmer and the gauge, and collect data after clicking the Write button. So what are the necessary modifications that i have to do to make the application running.

Thank you.

I found the way to communicate with all elements of the application. But now can anyone explain us how the PC receive and transmit data (an example of code will be very helpful) ???

(Where are you clive1  ???)

Thank you
