Testing

To debug the driver, please set the VFS5011_DEBUGPATH environment variable to a directory where lots of debug files will be created (the directory must already exist). For example, you can run fprint_demo like this:

VFS5011_DEBUGPATH=~/fprint_rindex_finger fprint_demo

(and scan right index finger multiple times)

These debug files will provide valuable feedback that can help developing the driver. But I would like to mention that the .pgm images that will be created this way will contain images of scanned fingerprints. So, if you have access to some top security military base where fingerprints are used for authentication, don't send me these images :-)
