Example of SPI communication between Particle Photon and Arduino

Hello

I feel like I have scratched through the entire internet now, but I can not seem to find any simple working examples of SPI-communication between Photon and Arduino.

I want the Photon to be a master, and Arduino to be slave.

Could you please help me with a simple example that send "Hello World" from the Photon, where as the Arduino prints this message to the console log.

Preferably also the Arduino sends a message back to the Photon, telling it that it received the message successfully.

Thanks alot!

So what is a photon in this context ?

That's probably a good idea. Will try!
Thanks.
