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

2024-12-30
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...

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

2024-12-29
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...

What is the correct connection for VCAP1 and VCAP2?

2024-08-07
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...

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

2024-08-07
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 ...

Do I need to connect VSSDSI when not using the display blocks?

2024-08-07
Hello,I'm using a STM32F479VI but I do not need the DSI (display) functionality for my current application.It seems that block runs on a independent power supply derived from VDD.Can I leave the DSI power pins floating or should I power them anyway?
