Hi I am building a circuit and I want to verify that what I am doing can be done (and with the parts that I intend to use). I have Freeduino, that I will connect to a Xbee, the Xbee will communicate wireless to another Xbee that sends its signal to a MAX7219 to multiplex about 50 LEDs. I think that once the Xbee network is up, that I can seamlessly communicate between the Arduino and the MAX7219 with SPI.
Is that correct? Am I missing some essential steps here? I am just going for the big picture, I am capable enough to dig through the data sheets and the playground documentation to get the details working (I hope).
Your advice is much appreciated.
