ok looks like some airlift defines need fixin'

brentru commented 5 years ago

@ladyada I'm not sure how master passed, it shouldn't have. The SAMD-boards wont compile on AdafruitIO_WiFi without the definitions for USE_AIRLIFT or USE_WINC1500 specified in config.h.

ESP8266 will compile OK, since it doesn't require either of those definitions.

I'm not sure how/if I could pre-define them for the travis build?

@ladyada Got travis to pass, merging in!
