Can I run multiple SPI devices on the same arduino? The communication wouldn't be at the same time. Would I jump the existing wires and simply add the new slave select? So basically the 5v, ground, clock, data in, and data out shouldnt have to change and I simply add a new pin to tell it when to go high/low?
If this isnt right, any guidance?
Also, if it makes any difference, I am driving a 7segment LCD and that works great right now. I am trying to add an external EEPROM to my arduino also, but haven't picked a specific chip yet.
You can run the devices on a parallel bus as you described. I would
use a pull-up or pull-down resistor on each CS line so that on
power-up each device is disabled.
