How does the USB peripheral behaves in the scenario where a single endpoint is configured for both bulk transmission and reception with double buffer mechanism?
Hello,I am using MCU STM32F303VC controller with USB 2.0 FS configuration as device and PC as the host.CDC interface is configured to handle the Bulk transactions, and for this only 1 endpoint (Endpoint 1) has been used for handling both IN and OUT b...
Resolved! strange problem with lwip udp, only broadcast address works
I'm using stm32cubeMX to create the project on a nucleo F767ZI boardI'm using FreeRTOS and LWIP for a simple UDP sender.I can get IP address form DHCP and ping works, and the packet can be sentout without any problem if the destination is the broadca...
DFU mode is working but normal USB don't. Windows 10 device manager says "device descriptor failed"
Hello everyone,I have CNC controller with STM32F207 MCU and during operation machine stopped and on software was message "load BIN file". After a wile I found bin file for exact model of particular board on manufacturers site, downloaded it and impor...

In order to evaluate emWin graphics library, I'm using the evaluation board STM32H745I-DISCO and I'm trying the example project "STemWin_HelloWorld".When I call GUI_DispStringAt ("hello",0,0) I see that the string is not displayed from X = 0 position...
[STM32H743] USB DFU cannot write to Flash Bank 2
Hello,I tried to use the factory DFU bootloader to program an image via USB. Everything works until the DFU utility tries to write/erase anything in Bank 2 of the Flash (from 0x8100000). When I try to write data to this region, the DFU utility just p...
STM32F0x: RX fifo threshold not set according to data width by LL drivers
Hi, i noticed, that the LL driver does not set the RX fifo threshold levels according to the datasheet:" Rx buffer not empty (RXNE) The RXNE flag is set depending on the FRXTH bit value in the SPIx_CR2 register: • If FRXTH is set, RXNE g...
