Config File

The file config.txt is read at startup and can be re-read during VT operation by press the 'CFG' button. The config file format is that of an 'INI file' [1]. There are two sections from this file that are processed.

• selected : any variable listed in this section will be automatically selected when the config file is read.
• axis_limits : a list of key=value pairs where the key is the variable name and the value is a 2 element vector that specifies that minimum and maximum y-axis. Variables listed in this section are also selected by default.

[selected]
# these variables are selected 
Valve_in_td
Valve_in_ad
Valve_in_hs1

[axis_limits]
# specify axis limits and select the variables
Valve_in_pd=[-51,40]
Valve_in_fd=[2,5]
Valve_in_vd=[1,10];

Note : the section names should be lower case, however case of the variables is ignored.
