Arducam-F REV.C and Arduino Uno R3 - Empty Image in SD card

Hello!!
I am a beginner in Arduino.
I am using a Arducam and Uno to take a photo and save in SD card. So I am using the demo of Arducam.

I have some problems. I can't upload last version of demo.

when I use the V1.3.0 I have a error

sketch_apr24a:40: error: 'OV2640' was not declared in this scope

And I change OV2640 for 5 and it's upload. But give me a empty image.

Can you help me??
I am doing a thesis and it is important for me.

Thanks,
Alban

And I change OV2640 for 5 and it's upload. But give me a empty image.

Say what?

I am doing a thesis and it is important for me.

What's your thesis topic? Obfuscation? How to be clueless? How to get others to do your work for you without even a clue?

First I'm checking if the hardware works. So I am using the Demo of ArduCAM.
when I use this code give me a error that OV2640 was not declared in the scope. So I change to 5 and works.
I don't no why when I take a picture the sd card give me a empty file.
Hardware:
OV2640
Arducam-f rev.c
Uno r3

sketch_apr24a.ino (3.27 KB)

In Arducam.h there is a #define OV2640 5 and it should works.

I don't no why when I take a picture the sd card give me a empty file.

And you have no serial output statements to determine why?

What, exactly, IS your thesis topic?

I'm automating a table of noughts and crosses. For this I use a camera to identify the positions through the analysis of colors. Communicate with HMI and HMI with PLC

Hello Alban01,
Is your ArduCam working via SPI? regards!
