Compatibility with Parallax RFID

[memelab74]

Hi,

I can get your library to work great on its own, but I when I try to include it in a sketch that interfaces with a Parallax RFID Reader, the RFID reader does not respond. I have tested the RFID Reader code separately. I know this might not be enough information for you, but basically: the RFID Reader can be configured to communicate over SoftwareSerial, but after WiFi.begin(ssid, pass), the RFID Reader no longer responds. It seems like there is something in the routines that is jamming the communication. If I comment out Wifi.begin(ssid, pass) it works fine, but of course, it removes the WiFi functionality!

I was able to run scripts with this Reader and CC3000 working using the Adafruit CC3000 library, but I'd prefer to use yours because it's easier to work with.

Any help or ideas would be appreciated.

Thank you.
George

Actually, I may have figured it out. I had the RFID Reader connected to Pin 6 which is reserved for a LED. So this is my second question/issue pertaining to pins. It might be worth a quick update to the README either directing people to the appropriate lines in host_spi.cpp where pins are defined or just making a quick list of which pins are reserved/off-limits so they don't have to go hunting through the code.

ANother option would be allowing the use of LEDs to be configurable/optional since on an Uno, reserving two pins for components that might not ever be used seems wasteful.

Thanks again for sharing your library.
