HAL_DMA_XFER_CPLT_CB_ID not firing - STM32H7

Looking at this post pwm and callbacksIt does indeed look like the PWM pulse callback is used rather than the HAL_DMA_XFER_CPLT_CB_ID CalllbackI have set up DMA to transfer to PWM. It is a circular buffer so I am just changing the pointer "audio_chan...

I am designing a board with STM32 device of P/N STM32G4A1KEUx. I am trying to see if I need to have an external pull up on the USB-FS D+ line for detection. The usual application note don't seem to include this device as it looks.

Resolved! STM32L4 SPI SD Card with FATfs and USB MSC

Hi all, I am working on a custom data logging board using STM32L4 and an SD NAND (uSD card in form of an IC). Since the SD chip is a surface-mounted IC (https://www.adafruit.com/product/4899) on the board using SPI and FATfs so I want to implement US...

Resolved! Modify usbd_stoge_if.c to use SD Card trougth SPI

Hi to all,I managed to interface with the SD card through the SPI and the FaTFS library (thanks to https://01001000.xyz/2020-08-09-Tutorial-STM32CubeIDE-SD-card/) now I need to implement a USB mass storage device on the same hardware.i don't know how...
