Bonjour,
Je me permets de vous contacter suite à l’achat de deux Arducams OV5642.
Après plusieurs tentatives infructueuses, je n’arrive malheureusement pas à obtenir de visuel.
J’ai réalisé le montage ci-dessous avec le code en pièce jointe.
Vous trouverez également ci-dessous l’écran d’Arducam_Host après téléversement du code.
Sauriez-vous d’où peut provenir le problème ?
Hello,
Don’t worry and I will try my best to help you. Please attach me the demo you are using. I will help you check it in detail.
Hi everybody,
Thx to rescue me in my problem 
I used the demo code below.
I have to add every times theses librairies in the code (OV5642_MINI_5MP ; OV5642_CAM ; “OV5642_regs.h”). Otherwise, I have an error message.
Then, the application said me “Spi is ok” and he detected my cam. But I have no images or vision which launches (even if I push “Capture”).
My camera is new and my Arduino (Uno and Mega, I tried both) works with others projets.
I’m a front of a wall :).
Damien

Hi,
Please test with our unmodified demo first, select the correct camera in memorysaver. h, and do not add the macro definition in the demo code.
Hi,
I did what you adviced and I got this error message:
<b></b><i></i><u></u><span style=“text-decoration: line-through;”></span>
It’s the same error message I had on all demos. It seems that it doesn’t find my librairy (Arducam), however it’s defined.
I tried to download it again but the problem persists.
Hi,
I did what you advices. I had this error message.
<b></b><i></i><u></u><span style=“text-decoration: line-through;”></span>
I had this message on all my tests with Arducam. Although it seems it doesn’t find my librairy (Arducam), it’s installed.
I tried to download it again but the problem persists.
Hi,
Thx for your answer. I tried what you advised.
The error message is , at the beginning, on this line:
I have this message with all demos. It seems that the software doesn’t find my library but it’s included. I tried to download it again but the problem persists.
hi,

Although it seems that it doesn’t find the library(Arducam), it’s included.
I try to download it again but the problem persists.
Hi,
If you have selected the correct board and turned on the corresponding camera in memorysaver. h, you still have the above error, then it maybe the library was placed in the wrong path, please make sure ArduCAM is under the installation path of Arduino, similar to: D:\Program Files (x86)\Arduino\libraries
This is my file path.
Hi,
My Arducam library is under the installation path of Arduino:
<b></b><i></i><u></u><span style=“text-decoration: line-through;”></span>
Hi,
Now you have confirmed the library path is right, have you chosen the right board?Which board did you choose? I suggest you follow this video in detail.
Hi,
I checked up my Arduino IDE and I used the same board than the video (Arduino UNO/ Com4)
I compared with my device manager and COM4 is the right port.
I tried to do the same thing than the video but without success.
I used 2 demos: “Mini_5MP_OV5642_Plus_Functions” and “Mini_5MP_Plus_OV5642_RAW”.
In both cases, the program didn’t find the library:
At the beginning in “OV5642_Plus_Functions”, the “if library is defined” was in comment (//) and the error message was on this line :“myCAM.rdSensorReg16_8(OV5642_CHIPID_HIGH, &vid)”. I think it’s the same problem and the program doesn’t find the library.
By the past, I already tried to install Arducam library again, without success.
Hello,
At this point, I think you can only completely remove your Arduino software, then re-install it, and operate it according to our video again.If it still can’t find the library, please let me help you with the remote software.
Hi,
I removed my Arduino software and reninstalled it again. I followed the video but I always got the same problem…
How do you want to do?
Hi,
This demo is used for 5mp plus, so you should open the memorysaver.h file which is under the Arducam path and enable the Arducam_mini_5mp_plus
Hi bin,
As you can see on the picture, my hardware platform is the right one.
I tried to select/unselect my camera module but It isn’t the problem.
I checked up my Arduino IDE, it’s good.
I unistalled and installed the Arduino and Arducam Package again, no results 
Yes, I can.
How do you want to do?
Hi,
Our working hours are from 8.30 am to 5.30 PM From Monday to Friday, Beijing time. You can choose a time to turn on your computer and send TeamViewer’s account and password to our email([email protected]). We will help you remotely.
