Currently trying to use the HTML server code to host Web pages from a UBW32 board. On their own, the SD card and Wifi modules work great, but as soon as I start up the ProcessServer() code in the sketch, I lose all interaction with the SD card and cannot access data there.

The same sketch works with the uno32 board just fine, so I'm trying to figure out what changes with using the UBW32 board. I assume that it is some sort of contention issue with the SPI port. Has any one else had a similar issue or might know of a solution? Thanks in advance!

Figured it out! Just need to add the UBW board to the list of boards that will disable INT1 when the SD Card chip select pin is pulled down.
