Hi,i created a project to connect the STM32F407VGTX by USB High Speed to a PC. It is enumerated as a Camera in the device manager. When start the windows camera app or VLC the videostream (Format MJPEG 400x240 pixel) starts. I use two picture toggeli...

For STM32H745IIKx I use:void __MX_CRC_Init__(void) { /* USER CODE BEGIN CRC_Init 0 */ /* USER CODE END CRC_Init 0 */ /* USER CODE BEGIN CRC_Init 1 */ /* USER CODE END CRC_Init 1 */ hcrc.Instance = CRC; hcrc.Init.DefaultPolynomialUse...

I had the same problem!Calling `HAL_IWDG_Refresh(&hiwdg)` before `MX_IWDG_Init()` caused this error...

Hi,is it possible to use/activate 3 isochronous transactions per microframe? /* High speed Isochronous Endpoint: MULT setting.*/#define UVC_ISO_EP_HS_MULT (2 << 3) Edit: Found the Problem. I needed to increase the amount of send bytes to force the p...

Hi,here is an example to show how the HAL_CRC_Calculate is working (STM32F407,STM32F107,...) and how to do the same calculation by yourself: uint32_t Crc32(uint32_t Crc, uint32_t Data) { uint8_t i; Crc = Crc ^ Data; for(i=0; i<32; i++) if (...

Update:I use the UVC which is included in the package: AL94.I-CUBE-USBD-COMPOSITEWhen the camera app will be closed the NAK bit in the OTG_HS_DIEPINTx register will be set and the IISOIXFR bit in the OTG_HS_GINTSTS register.So I guess when camera app...
