HID IN data transmission frequency is only about 10 times per second

I used ThreadX and USBX in the project. When I only use USB as a HID Device, STM32 can transmit data to the PC 1000 times per second, but when I use USB as a CDC+HID composite device, the transmission frequency of HID is greatly reduced. Will increas...

STM32F105 DFU BootLoader does not work

I successfully used USB DFU on STM32H7, and I want to perform the same operation on STM32F105. I learned from the manual that the system BootLoader address is 0x1FFFB000. But when I try to jump into USB DFU mode, windows prompts the device descriptor...

How to transmit and receive float type variable with TCP LwIP?

Hi,I am trying to send and receive the float variable between STM32H745 and my PC. I can only transmit and receive strings. Is it even possible to handle any type of data rather than string. Thank you.

I'm working with NUCLEO-H743ZI2 (1.8V) and having difficulties maximizing throughput with FreeRTOS+LwIP+TCP. I've managed to get 10Mbits but not 100Mbits.I would appreciate any suggestions on configuration parameters, settings, etc. that could help.
