SD Fat Adafruit fork and sd fat by Bill Geiman conflict
These two libraries conflict, they can not be installed at the same time!!!! If you want to use exfat for an arduino sd card you HAVE to use sd fat library by Bill Geiman!!! However tinyusb only seems to work with SD Fat Adafruit fork library for QSPI, and does not support exfat. Fix this please!!!! If I am right they use the same name for the library include.... (SDfat.h) Thanks, seems easiest way to fix this is to update the SD Fat Fork by Adafruit to support exfat.
I just realized the same guy wrote both libraries!!!! That doesn't make me any less confused though LOL!!!
