Hello,I plan to modify the USB Audio Class for a project created in STM32CubeIDE and using the USB Middleware library. I select the peripherals I need in the Device Configuration Tool, plus the USB_DEVICe Audio class. then I generate the code.In all ...

My end goal is to have an USB-to-I2S device running on STM32F411, built using the HAL and customizable.I'm trying to port the USB Audio 1.0 Playback example from https://www.st.com/en/embedded-software/x-cube-usb-audio.html to an STM32F411 target. X-...

I'm trying to create a composite HID device, mouse+joystick. I'm using the HID mouse profile as a starting point and then add a second interface. I also used an already existing example as a guide: the Arduino core based on the HAL is maintained by S...

I'm struggling to get a composite HID device to work properly.I started from the Mouse HID device and built a basic example. Mouse by itself works. Then I modified that example to impersonate a joystick. and that works, too.Then I create a composite ...

I'm planning to use a cheap STM32 board (either with a F103 or F401/11) as a joystick/rotary encoder controller for arcade games. I already have a working proof of concept using the old STM32duino cores (not HAL based), but I prefer to use the HAL en...

The problem is not my own version tracking, that's easy to do. It's about finding someone else's code, and being unable to know what version of the libraries they used. And I didn't propose to update every single file for each release, just incremen...

Please note I did say "middleware", not "firmware". Yes, I perfectly understand it's a tool limitation. And I also understand that it would be extremely simple to solve, either with a checkbox in the code generation part, or using sections of the cod...

Thanks for chiming inThere are two things that endlessly annoy me with the ST tools: this one, which would be easy to solve, and the fact that none of the files in device libraries has a version number. I frequently find projects online that I want t...

To answer my own question for posterity (it's really unpleasant to search for a topic, find the right thread, but no conclusion), I had to modify also the function USBD_LL_Init() in target/usbd_conf.c as follows. Sooner or later I will post this proj...
