I know the default Arduino SD library was ported, but has anyone attempted SdFat? I have a big project that I’d like to bring over to Spark Core, but it makes extensive use of SdFat. The native Arduino SD library is actually based on an ancient branch of SdFat, and the library has gone on to become much more efficient since the Arduino team copied it to their /library folder. Unfortunately much of the syntax has changed since then too, so converting my code to be backwards compatible is proving difficult.
For what it’s worth, SdFat “just works” with Teensy 3.0, so hopefully it’s not a tough port? (Famous last words.) I wish setting up a local dev toolchain was easier, or I’d try it myself. I would be so grateful if anyone could help make this happen.
