DCMI D1 waveform not showing

I'm trying to get image data through DCMI using ov2640, but other pins' signals come out well, but D0's signals don't show waveforms

Hardware connectivity is no problem.

Is there anything I should pay attention to in software or clock?

Hello @achovy ,

Could you please precise which STM32 device and Pins are you using?

Could you please refer to the STM32 datasheet and check the GPIO speed in your configuration? Are you use an maximum output speed high?

Thank you.
