Hello,we have some trouble with STM32H742, trying to flash it via bootloader. It seems to accept only every second line of a hex file. We receive a hexfile with another microcontroller, build the bootloader commands and perform the bootloader communi...
I'm using an STM32L496 on a custom board and using USB CDC configured through CubeMX (STM32Cube FW_L4 V1.14.0). This connects to a Windows 10 laptop. Randomly I get "USB device not recognised". I can go days without the issue and then it suddenly ap...
HiThe development of HID using STM32, such as mouse class and user-defined class, is very smooth, but the latest project uses hid power devices, which is a subclass protocol under hid, so I don't know how to deal with the report descriptors, so I nee...
I'm busy with a USB to Ethernet implementation using the ST USB library and LwIP.When I send a packet to the host (Data IN) that came from the ethernet interface, I know where is the end of an ethernet frame send a zero length packet (ZLP) accordingl...
I have taken the STM32Cube_FW_F1_V1.8.0 example CDC_Standalone and adapted it to my purposes. The original example intends to forward bi-direction USB communication over a serial port. I have removed the serial port stuff and intend to simply send me...
When using STM32G431RBT6, Only if the filter is configured to 0 can the interrupt be entered normally, otherwise the interrupt is always not entered. AnalogWDGConfig.FilteringConfig = ADC_AWD_FILTERING_NONE.
I need create composite device for the Virtual com and USART1 also USART2.That meaning when we connect the stm32 to PC show 3 COM ports,it's Possible to do that with STM32F042x6?i need help to create the composite device? or see a good example to do ...
I have done this: 1) created a file using fatfs on flash open and read ,it is working. 2) created a usb interface configured as msc device,when plugged into pc, new drive gets created, however it asks to format it. I have added only read functionali...

Hello,I am working on a project where I am interfacing SD card with SPI using USB MSC with STM32F103 processor. I could achieve reading speed of 580 MB/s. I am using HAL library. For the sake of improving the program, I want the USB to work with dou...
