Method readData

external/floppybridge/src/ArduinoFloppyBridge.cpp:292–305

Called when data should be read from the drive. pll: supplied if you use it maxBufferSize: Maximum number of RotationExtractor::MFMSample in the buffer. If we're trying to detect a disk, this might be set VERY LOW buffer: Where to save to. When a buffer is saved, position 0 MUST be where the INDEX pulse is. RevolutionExtractor will do this for you indexMarker: Used by rotationEx

//		onRotation: A function you should call for each complete revolution received.  If the function returns FALSE then you should abort reading, else keep sending revolutions
// Returns: ReadResponse, explains its self

// Called for a direct read. This does not match up a rotation and should be used with the pll initialized with the LinearExtractor
