According to this source, the RPI can use arbitrary gpio pins as CS lines for more than 2 spi devices

It seems like this library has the pin configuration hard-coded to spi0.

Ideally Id like to drive 18 different RC522s from the same raspberry pi, although only one of them needs to be active at any given time.
