I have a report descriptor that consist of 456 bytes. The problem is : When i define USBD_CUSTOM_HID_REPORT_DESC_SIZE 456 in usbd_conf.h file, it raises overlow warning and my hid device no longer works. How can i define hid descriptor size bigge...
I want to use STM32F070F6 usb dfu mode to upload program. The document An2606 page 53 says:If HSE is present and has a value of 24, 18, 16, 12, 8, 6, 4 MHz, the system clock is configured to 48 MHz with HSE as clock source. The DFU interface, USART1,...
I have to know if the file will stay into the mcu memory in this way and if the c program will work or if this idea il wrong and i cant do in this way.
Hello, I'm having trouble about use of lwip on Stm32h743. I'm using udp raw. I'm transmitting packet with 1ms period, there is no problem in sending/receiving. After 20-30 min, program is going to hardfault with 'Imprecise data access violation'. It ...
I have a STM32G431 project that was originally created with STM32CubeMX using HAL drivers. I need to port some of this code to another project that was originally built by CubeMX using LL Drivers by another engineer.The specific problem I have is my ...

I am using an STM32F407 processor chip and want to operate as I2C Master on two interfaces, I2C2 and I2C3. It is essential for our application that both busses can be utilised efficiently (with minimal gaps between transactions) and at the same time....
In https://github.com/STMicroelectronics/STM32CubeL0/tree/master/Projects/32L0538DISCOVERY/Demonstrations/Config there are two files, usbh_conf.c and usbh_conf.h, which appear to be redundant.Or am I missing something?JW
