Dear Community,I was trying to make composite USB2.0 device (FullSpeed) consisting of a UVC and HID component. Both the components I’ve tested before as a standalone device successfully. However after making a composite device accordingly to the HID-...

Posted on July 05, 2018 at 16:49Dear Community,I am trying to migrate some code of a STM32F4 series ÂµC relying on the StandardPeripheralLib to STM32F7 â€œlow layerâ€� driver concept. Unfortunately the LL-Driver concept is not that identical to Stan...

Posted on July 03, 2018 at 13:48Iâ€™ve setup a DSP application including a F32 FFT that takes on STM32F407 about 5 ms and on a STM32F429 approximately .5 ms. The clock settings are in both cases the highest possible values (STM32F407 -> 168 MHz and...

Hi,and thank you for responding to my question. Actually it seems to be possible to interconnect the USB3300 waveshare board and the stm32f407 discovery. However not using flying jumper wires because of combination of contact resistance and due to th...

Dear Jan,thank you very much - clarifying the fact, that setup packets are arriving at ep0 and thus passing the USB stacks internal mechanism: DCD_HandleSof_ISR(pdev) -> static uint8_t USBD_SetupStage(USB_OTG_CORE_HAND...

Posted on July 12, 2018 at 10:37Hi Jan,yes I've used the debugger and a volatile count++ placed inside the ISR. But to be sure that I've not overlooked something I've setup the experiment again: I've placed again a count++ (volatile int) inside the ...

Posted on July 09, 2018 at 13:39Hi - and thankyou for responding. Iâ€™ve found AN4660 for a migration F42/43 to F7 and it looks like DMA and ADC should be fully compatible (as expected). However it does not cover how in detail Iâ€™ve to change my pe...
