Hello, the CubeMX file is not relevant and it does not contain any IRQ or DMA settings. It was just a basic template for F4 without anything WS2812B related. I've removed it. I don't use CubeMX at all so I cannot give you screenshots or help with that.
So, generate project with CubeMX and then add my library to your project.
