Mini Ov2460 2MP Arducam - not working on Arduino Pro Mini

Mini Ov2460 2MP Arducam - not working on Arduino Pro Mini :

I purchased a couple of the OV2640_MINI_2MP Cameras , under the hope of using them on my robot projects.

I followed the directions for hooking them up to the Arduino Uno - but used Arduino Pro Mini instead.
I modified memorysaver.h :
enabling :
#define OV2640_MINI_2MP

I used d12 / d13 for SDA / SCL pins.

I loaded and compiled : ArduCAM_Mini_2MP_OV2640_functions
I ran ArduCAM_Host_V2.exe
It states :

  • COM is Open!
  • Arducam Start!

On Capture Clk:

  • ArduCam Single
  • Arducam start single Shot
  • Cam Capture Done

But I do NOT see :

  • SPI Interface OK
  • OV2640 detected!

And NO Image is returned / presented in Windows.

I also tried Continuous Video , still nothing.
But, I CAN see the Receive Led Continuously Blinking on the Arduino Serial Adapter.

Does anybody have any ideas ???

Perhaps post the actual code you are using.

There seems to be some confusion;

"I used d12 / d13 for SDA / SCL pins"

"SPI Interface OK"

d12 and d13 are the MISO and SCK pins of the SPI interface.
The SDA and SCL pins on the Pro Mini are for the I2C interface and are fixed at A4 and A5 repectively.
