why is it yellow are you setting it up in YCbCr? if we set registers to RGB will it output in rgb? also is it ov7670 with or without fifo? ive read articles saying pi 3 model b cant interface the ov7670 cuz of gpio limitations but i see arduino uno referesh rate is much slower but still works and youre doing it on pi zero which is same as pi SBC not pi pico (microcontroller)
The frame of the cam is YUV so the default and in this example only pixel intensivity is read and transmited to pc (because the usb-uart i got there is slow speed), on screen in the windows app the color is only set as an example how the bitmaps work there. I would have to check the registers but i think i didn't use fifo. For the rgb You have to write to one register as I remember and the output is one byte blue+green next green+red (or something like that). If I get some free time I can do the cam example with rpi3b and linux user space, the key to run the camera is to supply at least 7MHz main clock.
