USB DFU Bootloader for STM32F730

Hello,I noticed that in AN3156 (USB DFU protocol used in the STM32 bootloader), STM32F730xx MCUs are not listed in the table of applicable products on the first page. Does the F730 really not come with a USB DFU bootloader? Or is this omission uninte...

sd card cannot be accessed with SDMMC in 4-bit mode

I have set the parameter "mode" in CubeMx to SD 4 bits wide bus.But after doing so, I cannot access newer SD cards (HX) any more. Older cards (512 MB) work fine, which I assume is due to the fact that these cards do not support the 4-bit access from ...

Hello, I want to build a System with STM32H743ZI and Camera Sensor OV9655. I use DCMI and I2C Interface. Is there any example code which I can use? I would like to use HAL.library but if there is any code it would help a lot. Kind regards Tim

I am using the HAL receive_IT and transmit_IT successfully but occasionally as the transmit is being setup part way through the receive message the receive interrupt fails to get enabled and an overrun error occurs. Does anyone have a solution for this?

I receive the data byte by byte and I can see that the only time that it fails is at the beginning of the transmit. It looks like the HAL is busy starting the transmit so it cannot re-enable the receive interrupt after the previous byte has been rec...
