ArduCAM mini with 4 Cameras Adapter Board SD card error #6

Open xDaya opened 8 years ago

xDaya commented 8 years ago

Hi,

I have been working with a normal ArduCAM shield before, and first of all I am very happy that it exists! I have switched to an ArduCAM mini OV2640 now, because I want to make a smaller device that is more flexible. As I wanted to do some experiments with multiple cameras as well, I bought the 4 Cameras Adapter Board.

I have been able to get the combination running (1 ArduCAM mini with the adapter board) through the software you provided. However, my next step is to save pictures on the SD card. For that, I am trying to run the example code ArduCAM mini 2MP TimeLapse 2SD, bot on an Arduino UNO and an Arduino Mega 2560. On both boards it gives me the message 'SD card error' though.

Do you know what might be causing this problem and how I might solve it? At the moment I attached the board directly to the Arduino without extra wires.

Thank you!

Dear Sir, Sorry for my late reply. Would you please send us your configuration of the whole system. I will try my best to help you resolve the problem.

Any question else,please feel free to let us know. Best Regards, Lee

Hello , I am Working with Arducam ov5642 module! I want to trigger four modules at the same time and want to see the images via serial monitor or any .exe host application. I am not able to find an host application for Arducam 0v5642 4Cams burst.ino! Can anyone please help me??

Hi

I also has same issue of xDaya. xDaya if you ave solved your issue can you post the solution. I appreciate it.

Thank you.

BrahMOs94 commented 8 years ago

hello lee, Actually I have only two modules I tried triggering those modules using ARDUCAM_5mp_4Cams_burst program and I also used the host application which you sent me ! But there is a problem when I press the capture button the camera modules are not capturing the photos,whereas when I change the resolution in the dropdown list to the maximum these two camera modules are capturing photos! I am not sure wheather i have explained my query effectively! And I also want to know wheather I can trigger the camera modules at the same time I mean in this program the camera modules are triggered sequentially , I want to trigger these modules Simultaneously!! Please reply as soon as possible, Regards

xDaya commented 8 years ago

I'm sorry I didn't reply anymore. Thank you for your answer, I solved the problem by attaching the ArduCam mini without the shield; it seems as if the shield is not fully compatible with the SPI pins of the Arduino Mega 2560.

htr99 commented 8 years ago

Hi xDaya,

Thank for your response. Did you change the code? I men otherthan changing SPI CS pin definitions? Anyway I'm using UNO and Stil gets same issue.

xDaya commented 8 years ago

I didn't just change the SPI CS pin definitions, I rewired the ArduCam completely and didn't use the shield anymore. Besides that I believe I didn't change the code, and it makes sense, since the SPI pins on Arduino Uno are 11, 12 and 13, whereas on the Mega they are 50, 51 and 52. I think that is why the shield doesn't work properly with the Mega.

htr99 commented 8 years ago

Hi Xdaya,

In your first post you have mentioned on UNO board also you got same SD card error message. So then problem may exist with ardu cam adapter somehow. Did you successful with ARDU CAM ADAPTER board + UNO set up?

xDaya commented 8 years ago

I'm afraid I haven't, because I was quite sure I needed the Mega, and wiring it without the adapter board was a better option for what I was trying to make anyway. If you want to try that I can show you how I made it work.

ArduCAM commented 8 years ago

Hi All, The arducam mini adapter board use ICSP connector for SPI signals, all arduino boards has the same pin definition on ICSP connector. So the adapter can work with any arduino boards and much easier to do the wring by hand.

ArduCAM commented 8 years ago

Hi, from your description it seems that you didn't initialize the camera properly. So please initialize the camera and set to correct resolution then start capture. And as you can see there is no external hardware trigger pin on the ArduCAM mini board, so we have to use SPI command to trigger the capture. The capture command time interval between each camera should be micro seconds, it is nearly the same time. Let me know if you need more help. Regards, Lee

Hi Lee, Any solution for my problem, I use Arduino uno, 4 Cam adapter board + your example code.

Thank you.

BrahMOs94 commented 8 years ago

Hello Lee, I have checked my camera initialization there is nothing wrong in that! I just wanna trigger two camera modules using ArduCAM 4Cams burst and that ArduCAM exe file which you sent me. I have checked the program so many times but I am not able to get continuous shots using two camera modules. If I press the capture button in the .exe application it is not responding. Even I tried commenting camera 3 and camera 4 in my ArduCAM program but nothing I'd happening. If I change the resolution in my .exe file then camera's are working that too not in a loop.. My question is can I trigger two camera modules using that host application and the ArduCAM program???? (If you check the program only camera 1 has been initialised I don't know the reason for that also, please let me know). Thank you On 12 Dec 2015 17:15, "Lee" notifications@github.com wrote:

Thanks for the program and host application Mr.Lee, It works perfectly fine. But the thing is even the lowest resolution 320 x 240 is buffering when I gave autocapture with the interval of 1000 milliseconds! Can't i improve the performance of ArduCAM And this host application is only supporting 32bit pc. It would be helpful if I get the same application for 64 bit pc. Thanks and waiting for your reply!

Hi again, Yes, the bottle neck of the performance is the serial baud rate, it is limited to 921600bps on both Arduino and PC app. In this case you have to delay enough time between sending two capture commands, or use fast MCU and use other interface like USB or Ethernet. I'm using Win10 64bit with our app, there is no problem, what do you mean the app can't support 64bit pc? Let me know if you need more help. Regards, Lee

Hello Lee Sorry the problem is with my PC and the code is working fine. I am not able to understand the complete sense of the program. Can you send me detail description or explanation of the program. So that I can understand the flow of the program. Thank you.
