Core 1 panic'ed (InstrFetchProhibited)

i connected it directly to my PC. it works, but when i changed the resolution from HD to full HD, it crashed. it happens a lot when changing settings.

and, i finally fixed the clock issue!

[josef2600]

fined it. if i make full HD and frame per second more than 5 or 6, it crashes. if i put clock to 24 MHz, it gets better, but in over 10 FPS, it still crashes. speed gets a little better, but in total, it gives me around 0.5 frame per second.

working with cam registers may assist

[josef2600]

thanks. i am currently on the registers, but they don't have any explanation in the datasheet. and many more problems. like in Arduino we don't have access to source code, and we have to use complex codes to work with them. even then, i am not sure if they work or not. i guess i have to test. but, yes it helps. for example, i still don't know how to set the PLL in it. it has few and no explaining.

[josef2600]

i just got a very important info. the camera DOES NOT include an internal clock source, BUT in some boards, they put an external clock oscillator to create a 24MHz clock for it.

this makes me interested!
