A question I couldn't find answered; perhaps my search terms were incorrect.
If you have an Octolively system, and would like external inputs (and/or outputs), what is the best way to do this?
You could reprogram the system, via the ISP, but that would leave you with the current sensors. Could you somehow use an Arduino (with its own sensors, inputs, outputs, shields, etc) to talk to the Octolively via that 6 pin connector? I see "Programming interface: Standard 6-pin AVR ISP (ICSP/SPI)", which sounds like you can use SPI (my own experience has been with I2C, but the idea of using SPI seems like it would work). Have the Arduino handle sensors and other stuff, have the Octolively handle the lights.
Thoughts on this scheme?
