I noticed that CubeH7 v1.10.0 comes with USB Device library v2.10.0 which supports new class drivers and composite device. However I can't find any document nor examples corresponds to those new features.ST, could you please update USB Device library...

I'd like to develop USB host application with Audio and/or Video class.Is there any working example project or code snippet?I checked STM32 HCD driver file - -ux_hcd_stam32_periodic_schedule.c, but it always generates EP_TYPE_INTR packet. How can I s...

I'd like to use MotionFX library on STM32H7 together with FreeRTOS and STemWin Middlewares. I noticed that MotionFX has been compiled with -mfloat-abi=softfp, but others are prepared for -mfloat-abi=hard.Could you please prepare "hard" ABI version o...

I'm having a problem to make USB CDC device driver work with FreeRTOS. If FreeRTOS is configured without TICKLESS_IDLE mode, USB CDC works fine. However, once TICKLESS_IDLE is enabled (or WFI is executed), I no longer able to finish USB enumeration p...

Posted on January 24, 2018 at 10:26I'd like to use STM32CubeProg with Nucleo-F767 via USB, but CubeProg fails to connect with 'Corrupted Data base' error. I've tried both Windows and MacOS versions, results same error.I guess STM_Prog_DB.xml is the ...

You need to convert YCbCr fromat into MCU format expected by the encoder.Please refer AN4996 for details.If DCMI frame rate is slow enough, you can use double buffering DMA technic and run software conversion process while receiving incoming YCbCcr d...

Yes, I know.I understand that you DON'T support ISOC out with Azure-RTOS/USBX andI have to make it work by myself.Thanks for your answer.

OK, I can live without examples.But, how can I send out ISOC audio stream packets?Do you mean that you don't have any plan to support ISOC packets?I can't find the HCD driver code which send out ISOC packets.Regards,

FYI. You can change the ST-LinkV3 MCO config to generate the clock from F723 HSE. But, resulted clock freq becomes 8.33MHz (sigh...)

Re: Can the hardware jpeg encoder of the STM32H743 encode YCbCr progressive scan from DCMI directly or some image preprocessing is needed before sending the frames to the encoder?
