How do I capture one image with K82F & OV7670 camera?

jwhammel1 — Mon, 15 Apr 2019 18:38:50 GMT

We have the example running that allows the K82F and the OV7670 camera to send video to Skype. We are trying to just capture one picture from the live video and save it in the easiest place. We are having trouble locating the files that send the video to Skype. We were thinking that this would be the best place to add code to save a single frame.

We initially had 6 errors but corrected 2 of them by including the missing files manually by following the instructions on webpage: AN5275_SW FlexIO demo compilation error in KDS shown below. We are trying to figure out the step in main.c but the application note "Relocating Code and Data Using the KDS GCC Linker File (.ld) for Kinetis" is not there. Do you have any recommendations for the remaining errors?

Hello,

Thanks for the response, I am referring to the application note and the

find the .ld file mentioned by you in the kds directory, however other

launches file are do available.

For reference i have attached the zip file and the image. Thanks for the

future response.

Hi,

Can't you see the attachment I pasted in my reply? Maybe you should change a browser. AN5275sw hasn't ld file. It use KDS's default ld file but need to be modify.

Jing

I looked at that post before and even replied to it days ago but no reply back. I couldn't find the mentioned app note: (Refer app note: Relocating Code and Data Using the KDS GCC Linker File (.ld) for Kinetis).
