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?

ADC in dual mode with sampling frequency of 10.66 MS/s (5.33 per ADC).The System clock is set to 120 MHzThe ADC clock is set to 80MHzThe ADC1 IN8 ext3 is trigged by TIM2 CC2.The ADC data transfet is done though DMA2 CH3

STM32F769i-DISCO Ethernet Speed

Hello,I am using STM32F769i-DISCO board in my project. The project include camera module and I get data from this module using DCMI. I want to send this data to computer via ethernet. For this I need at least 100Mbits/s ethernet speed. But I cant f...

MbedTLS mutual authentication failed if adding a task

HiI’m suffering a weird problem:I’d connected my board to my own Mosquitto broker over MBedTLS 2-way authentication, and pub/sub works.After adding a FreeRTOS timer to send keepAlive messages to broker by timer’s callback, I found my mutual auth fail...

STM32H747 USB CDC device not detected

I have an STM32H747I-DISCO board and try to connect it to a computer as a USB CDC device.I use CubeMX to configure the USB (USB_OTG_FS in Device_Only mode, USB_DEVICE_M7 with CDC class, 48MHz clock for the USB peripheral) but when the generated progr...
