Enumeration seems correct, I can select the audio device on the PC, but mem[] buffer is not filled if I send audio to the device. If I set the exact same settings for a F407 or 411, the mem[] buffer is filled by the incoming stream.I searched a lot w...

Tinyusb has no isochronous transfer support for the stm32F1xx and stm32F3xx family. I learned it the hard way, first tried it, and made an unsuccesful test. Then debugged it, and found the reason. Then Googled the forums and got the claim it's not su...

The version number of the STM32CubeMX increased. I hoped, that ST corrected the broken code.The HAL for the STM32F1 has not changed for a yearConsidering it's not working, and it's a known "feature", it's not good news.essentially identical to that o...

Sure, I hoped that the new HAL version is better.It's definitely an original ST uC from the good old times. I tried it with a Nucleo as well. I am pretty sure it's broken code.

The STM32F103 HAL usb audio library is still broken? The CubeMX generated code is not working with the F103 or 303, but working with F411.

The USB audio middleware is not working for me on STM32F103 or F303, but working with F411 or F407. Just the generated code, 48000 sample rate, increased heap, not a single own code line.
