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

SPI Cameras
1

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.
Quick Start Guide - Arducam
ArduCAM Mini Cameras Tutorial - Arducam

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 ???
