I'd like to connect two RingCoder breakout boards (https://www.sparkfun.com/products/11040) to a single ATMega328, but I'm a little bit confused about how to connect them both together.
I'm new to shift registers in general, but it seems that the RingCoder is not set up to allow for daisy chaining multiple modules on the same SPI bus. Or am I wrong about that?
I could use some pointers about which pins are common between the boards, and which must be separate. For example, I'm thinking that I need to connect both boards' GND, DAT, CLR, CLK, LATCH and VCC pins together (don't care about colors or switch right now), then bring the EN lines to two different pins of my ATMega328 so I can switch between the two boards. Is this correct?
