I noticed some interesting behavior from this beta SD library.
After running bench, the L LED (attached to the SCK line on my board, like an original Uno) remains lit. If I then set the pinMode to output and try to manually turn that led on or off, it just stays on.
A number of libraries access Serial. This causes HardwareSerial to be loaded even if you don't call the functions that access Serial. These libraries can't be used with SerialPort.
All released SD.h and SdFat libraries cause HardwareSerial to be loaded and can't be used with SerialPort. I will soon release a version of SdFat that does not access HardwareSerial.
A beta version of this SdFat is in SerialLoggerBeta20120108.zip here http://code.google.com/p/beta-lib/downloads/list
I was just wondering if there is an update to this beta?
