Arducam with Mega2560 r3

I am trying to connection an Arducam Mini-2MP-Plus to an Arduino Mega 2560 r3. I have tried to use both the configurations here and the modifications listed at (though these seem to only reference r0-2?). Using the pinout diagram for the r3, this is my latest attempt. Are there any update to guides I can reference? Program used is the stock “ArduCAM_Mini_2MP_Plus_functions”, tried with and without the extra “pinMode(A4, INPUT); pinMode(A5, INPUT);” lines from the article.


For the Mega2560 R3, I2C pins still use 20 and 21, SPI pins please use the following pins.
