@xiaocq2001 Is there any solution? This is really confusing

Is the interrupt FIFO FIFO 0? When I only use HID, it can work normally even if the HID FIFO is set very small. HAL_PCDEx_SetRxFiFo(&hpcd_USB_OTG_FS, 0x40); HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS, 0, 0x10); HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_FS,...

My HID IN endpoint is 0x83 CDC IN is 0x82 If TX FIFO1 is an interrupt endpoint, what is the purpose of configuring TX FIFO0?

So no matter what device type is used, RX FIFO and TX FIFO 0 are necessary. My current CDC IN uses 0x82 endpoint and HID IN uses 0x83 endpoint. Therefore,...

This is very strange. Could it be that USBX does not support the STM32F1 series?

The total FIFO of STM32F105RBT6 is 1.25K. My allocation is based on the needs. I allocate the same size of FIFO to STM32H750 and it can work normally.

I tried to report my current problems to the ST community, but I didn’t get any useful information. Can you contact the ST official?

@liydu I am looking forward to your reply

My clock is set to 72MHz and I use CubeMX to configure the timer and DMA. The library of ws2812 is included, but it does not work properly. Could you...

I haven’t paid attention to memory consumption. I tried cubemx for an afternoon, but I couldn’t control ws2812 successfully.
