Hi, for a few days I have been trying to run the OV7670 camera on the STM32F446RE (Nucleo), but the image it gets does not resemble what the camera is looking at, I have checked the connections many times, but I have not found any problem there, maybe someone of you had a similar problem to mine . I found the configuration of the camera registers on the network, but it did not improve the situation, my own register settings did not work either. Initially, I thought that the fault might be on the display side, but as you can see, the test image is displayed correctly. I use DCMI with DMA connection in DCMI_MODE_SNAPSHOT mode and then throw buffer from RAM to display.
