Working on programming AVR chips exposes a glaring omission in my
first design of the SPI Relay: not allowing multiple devices make
this task hard. I constantly have to unplug my SD card before, plug
the AVR chip holder, then play a bit, then unplug the AVR holder,
then replug the SD card...
My prototype for a SPI relay design is built, but I haven't tested
it yet. I need to adapt the code first, which is what I do here.
When the prototype is tested, I'll update the SDC recipe with a new
schema.
