I'm a LabVIEW developer and this is my first foray into Arduino and LVforArduino.

I'm building a simple access gateway to store and retrieve data files wirelessly from an Arduino target.  There doesn't appear to be a SD card 'File' or 'Directory List' function in the LabVIEW Palette and I need this as part of the application.  

There is a function in SD.h called 'openNextFile' and this is the root of a 'List Files' function.  I'm aware that the LVforArduino libraries are built around SD.h so does that mean that 'openNextFile' is there, but just not revealed as a VI call?  If it is what do I need to do to make that call.

Help and insight would be much appreciated.

In general terms, the Compiler allows any existing Arduino library to be ported and used in LabVIEW via the creation of a set of user API VIs that wrap around the Arduino library functions. Take a look at the Product User Manual as there is a user guide showing how one can do that. So, if a given library function hasn't been exposed as part of the Compiler itself, one can potentially use this method to create API VIs that do. Hope this helps.
