STM32 MCUs Embedded software

USB Sticks / Mass Storage devices of some make not detecting with STM32F407VET6 USB_FS configuration using only USB_OTG_FS_DP and USB_OTG_FS_DM pins.

we want to use USB mass storage devices like PEN drives in one of our project based on STM32F407VET6, in which we use only USB_OTG_FS_DP and USB_OTG_FS_DM pins for communication and generated VBUS by means of other IC's. we observing that some mass ...

Own USB OTG FS Mass storage Host for STM32H743IIT6 3.3V not coming

Hi, We are developing a custom board based on STM32H743IIT6 microcontroller. The application is USB mass storage acting as HostWe are using USB OTG_FS connection for the microcontroller. We are connecting the VDD33USB to 3.3V.  And here is the USB co...

Is there an example of reading and using audio from the on-board microphone of the STM32F469I Discovery kit? Details below

I am trying to access and read audio from the on-board microphone of my board and run it through a speech recognition model (Tensorflow lite speech commands). I am unable to find the audio library for my board or an example of accessing and using aud...

hid usb device function

I'm using 'STM32F103RCT' and been create a HID Custom keyboard.When the HID Keyboard disconnects from the computer, is there a function that occurs?

I use STM32 VirtualCom USB library it have two function CDC_Receive_FS(); and CDC_Transmit_FS();. These functions send and receive data arrays, how can I send and receive one byte at a time?

I'm looking for an Ethernet interface solution for a STM32L4S9 based design. Does anybody know of a reference design or evaluation board that is available to get me started?

I ported an application from STM32L496RG to L4Q5. Most of application is working except the ADC acquisition because of DMA and the new DMAMUX1. I used the LL ST library unfortunately I didn't find any LL example of ADC + DMAMUX. Could you give examples?
