USB Audio 2.0 on USB HS issue with STM32H7 series and USB3320 external PHY (Data transmission on Isochronous ISO IN EP (Feedback OR recording) abruptly stops being sent)

I've asynchronous USB Audio 2.0 implementation where speaker with feedback and microphone interfaces are configured.I have strange problem with audio Feedback and microphone respective interface which are Isochronous-in type.The issue observation is ...

STM32H747I-DISCO Data Acquisition Chain where to start?

Hi all,I am new to STM32 and tasked with a somehow complicated design.I must build a data acquisition chain using ADC in interleaved mode at the highest frequency possibile and dump data on a pc.On the ADC side I found this example which seems to be...

[STM32G431KBU3 - USBPD] - Problem when trying to use another ADC

Dear all,I wanted to develop a USB Power Delivery SINK project using my STM32G431KBU3 MCU.For that reason, I have designed a custom PCB and follwed carefully ST's WiKi:https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:STM32_Advance_USB-Power_Delivery...

Audio performances of STM32L476JGY6TR

Hi!We are starting to develop a product based on an STM32L476JGY6TR.Part of the system would be dealing with a mono audio stream at 6kHz (sampling frequency).I've read in the datasheet that this ST chip offers some audio capabilities using SAI interf...

Bootloader: jumping to either App A or App B

Hello​I​ am considering the following approach of the Bootloader.​We will divide the internal flash into :1. Bootloader 2. App A3. App BFor App A or B we will have a version number. Bootloader will read the version numbers of both and depending upon ...
