We are using the STM32 USB Device Library.This is the USB circuithttps://peter-ftp.co.uk/screenshots/20210511523173514.jpgDoes the STM library implement this, or do I need to detect a drop in VBUS (cable to Controller being disconnected), or is no ac...
Hello All,I am having an issue interfacing an SD card to the STM23H7.I am using the SDMMC1 with 4 bit wide bus. When testing HAL_SD_WriteBlocks , I can write and read from the card successfully at various lengths (different number of blocks). But I...
Hi,I'm trying to setup the SMARTMIC package on my STM32H743 board with the CCAO2M2 board and MEMS microphones, and I want to use the beamforming library (AcousticBF version V2.2.0). But when i call the BF_init function, I pass in the HardFault_Handle...
STM32L422kbHi,I have created a USB sensor project through MX cube as FreeRtos based CDC device in FS mode. The sensor is detected as a com port in the device manager while I connect to the USB port in my PC. But sometimes it won't, It detected as a D...
I am using F446 board with CCA02m2.when I just send the audio to USB output, I can record data in audacity. But if I do simple processing such as averaging data, the output is high clipped data.I checked the data range and overflowing. there is no pr...
If it does support EMC, how can I read some ID information from the cable?
I am using a STM32F4 on a custom board with USB configured as custom hid device.I need to know how to get the received data from the USB_ReadPacket placed inside the HAL_PCD_IRQHandler (I suppose this is the function called when the device receive da...
