16.57.3. Description

taler-mdb-display is a command-line tool that simply toggles the backlight setting. Depending on the hardware, this -i may be used to turn the light on or off. The opposite effect can then be achieved without the -i option.

Its options are as follows:

-c FILENAME | –config=FILENAME

Use the configuration and other resources for the command to operate from FILENAME.

-i | –backlight-invert

Invert the bit for turning on/off the backlight (without the option, the tool will do the opposite).

-h | –help

Print short help on options.

-L LOGLEVEL | –log=LOGLEVEL

Configure logging to use LOGLEVEL.

-l FILENAME | –logfile=FILENAME

Configure logging to write logs to FILENAME.

-v | –version

Print version information.
