Veryfing code using this library in Particle Build fails with this error:

Ah! The person who did the photon port left out pin/port mapping definitions for pins 8 and 9 for some reason - which is why what you're trying to build is failing. I'll look to see if I can find definitions for them - in the meantime, try using a pin other than 8 or 9.

Late here, but on a the Particle devices pins 8 & 9 don't exist so the mapping is - just like the pins - non-existent ;-)
