These excellent articles make the USBX worth a go for more complicated tasks (I wish composite devices were supported in CUBE IDE),How to implement the USB device composite class in STM32 using the Azure packageHow to implement the USB Device CDC (VC...

Following on from this question USB FS speed vs USB HS with internal FS Phy with DMA it seems that USB HS has access to DMA but there is no information on how this is configured. I do not see any additional DMA options appear in Cube IDE when I have...

I have spent a few days trying to select the correct MCU for a project and trying to minimise the need for external ICs For example, I need the STM32F479VI MCU to appear as a USB Full Speed (480 Mbps) device.However, in CubeIDE, when I select USB-OTG...

Hello,VCAP1 and VCAP2 are external capacitors for the core's voltage regulator.The data sheet for the STM32F479VI states that, "Stabilization for the main regulator is achieved by connecting an external capacitor CEXT to the VCAP1/VCAP2 pins."I inter...

Hello, This is how an STM32F479VI appears in CubeIDE without doing any configuration.DSI is actually disabled, but the pin are light green and set RESET_STATE when I hoover over them.What is CubeIDE trying to tell me?I do not want to use DSI in this ...

Hi Uwe,Thanks for pointing that out; I'll go with an external HS Phy.Regards,

Thanks @waclawek.jan and @tjaekel for the helpful comments. Yes, the bus matrix really helps understand these capabilities—thanks for pointing that out—I am learning!So it seems this is well within the capabilities of the MCU using double buffering a...

Hi Tesla,What type of USB Device are you trying to build? Can you sink/source the volume of data involved?It is a sensor board with external data processing rather than doing the number crunching on the MCU. So the aim here is to stream the collected...

Thanks, With so many options it was hard to find this clearly started. Your answer is appreciated! External PHY it is then. Regards,Daniel

I normally have NRST on MCU connected to 3.3V directly. Do I need to include a pull-down resistor if also connecting T_NRST to NRST? For example, 3.3V — [ 10k ] —- NRST/T_NRST Excuse the ASCII circuit, I’m on my phone.

CubeIDE how to configure USB HS with internal FS Phy for DMA transfer on STM32F4

Does STM32F479 support USB High Speed without an external PHY controller?

What is the correct connection for VCAP1 and VCAP2?

Why are DSI pins green when DSI is disabled, they say RESET_STATE.
