Trigger Automatic Reference Frame
This parameter allows you to define the number of rows or columns you wish to “clean” (remove the EMI noise) when a certain amount of touches happen (usually when you notice false touches around the edges).
Syntax:
$ displaxservice -a 127.0.0.1 --te2fnref o x y| o | number of lines (rows/columns) around the edges |
| x | number of touches to be considered to trigger this command |
| y | number of touches outside of the edges to be considered to trigger this command |
How to select one, two, three, or more lines around the edges (the value used in ‘o’):
Each column and row has a value of 50.
If you want to select:
| 1 line around the edges | o = 50 |
| 2 lines around the edges | o = 100 |
| 3 lines around the edges | o = 150 |
| N lines around the edges | o = 50 X N |
Values used in ‘x’:
From one to the maximum number of touches your SKIN supports. We recommend keeping this number at 2 or 3.
Values used in ‘y’:
From 0 to the maximum number of touches your SKIN supports. We recommend using 0, as the command will then only be triggered when no one is touching the SKIN (on the active area).
Example:
$ displaxservice --te2fnref 100 2 0The “--te2fnref” will be triggered when:
- inside of two lines (columns/rows around all the edges)
- there are 2 touches
- no one is touching the SKIN (0 touches) inside of the edges (active area)
If you want to make these changes permanent (save them to the Touch Controller), run the command:
$ displaxservice --device-settings saveRelated Articles
Trigger a Reference Frame
The Reference Frame feature consists of making a data record of the actual state of the sensor, to be used as a comparative measure for the next signal readings: $ displaxservice -a 127.0.0.1 --fnref
