Hi,

I'm having the exact same error "SPI Interface Error" as https://github.com/ArduCAM/Arduino/issues/141

Please find my circuit and code setup:

Kindly help.

I have found that adding some delay statements in the setup seems to help with the SPI errors. I have used two delay(3000). This seems to help on startup. yield() statements may also be useful.

Thank you @BDCowboy, I shall try that and get back to you asap.

@prasuchit The Mega 2560 board's SPI signal should be connect to ICSP .

@UCTRONICS , can you please elaborate on that? Are you talking about a connection on the board or something in the program?

@prasuchit Please refer to this schematic diagram icsp_signal_definition You should connect the SPI signal to here .

Ok, I figured it out, for anyone who is having this trouble in the future: (This was done with Arduino Mega, but I guess the principle is the same for all boards) Connect Vcc and Ground of the arducam board to the +5V and Ground on arduino. The CS pin from the arducam board to any digital pin on arduino and look for "const int SPI_CS = 49;" in the code that you are running and change that to that pin number. The rest of the pins, refer to the image: 8c003032-244a-11e7-99a5-eaff19225612

This worked for me after searching for a really long time. I don't know why arducam wouldn't have a diagram for mega. This worked for me with the 2MP Plus using MEGA

Thanks for your great suggestions. We will update our diagram for mega as soon as possible.
