it saying chiped_ not declared i put *** by it in the code so you can see
yes i did go to the memorysaver file and chose the right camera

I do not have the libraries, and don't want to find and install them, so cannot verify the code to see the exact text of the error. Please post the entire error message. Paraphrasing the error leaves out important information. If you are using the IDE there is a "copy error messages" button. Copy the error and paste into a post in a code block (code tags).

groundFungus · July 8, 2023, 6:33pm

The code is incomplete. Please post the whole code. We cannot verify incomplete code either. You are missing the loop() function.

Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in a code block.

It may help if you post the memorysaver.h file as well.

@larenzia93 don't keep making new threads on your problem with combining two sketches!

Instead just respond in one thread, then we all stay up to speed.

this would be so much easier if you posted the error messages

larenzia93 · July 8, 2023, 9:22pm

no it different

no its different

larenzia93 · July 8, 2023, 9:24pm

stop being so thirsty to flag people
this is a different code for a camera
ardu cam 5

the other codes were combing servo and ultrasonic

where is this defined?

alto777 · July 8, 2023, 11:18pm

To atone for my thirsty thirst, I googled looking for your missing symbol and found

The issue you specifically raised ( 'OV5642_CHIPID_HIGH' was not declared in this scope) may be resolved by modifying "memory_saver.h" to uncomment the preproccessor directive corresponding to your device. I'm assuming you are using the OV5642, so you should uncomment "#define OV5642_CAM" and comment the other #define's.

which may mean you do need to include memory_saver.h - last I saw it was commented out.

This

may also be an issue. The IDE had to select from multiple libraries. Be sure it is using the one you think, the one that was used by whoever wrote the beginning version of your sketch.
