Overview

The Automatic Reference Frame Trigger feature allows the Touch Controller to automatically “clean” noise from sensor edges when specific touch conditions are met.

This is especially useful when:

• False touches appear near sensor edges

• EMI fluctuates during operation

• Manual reference frames are impractical

Command Syntax

displaxservice -a 127.0.0.1 --te2fnref o x y

Parameters Explained

o – Edge Area Size
Defines how many rows/columns around the edges are affected.

Each row or column equals 50 units:

• 1 line → o = 50

• 2 lines → o = 100

• 3 lines → o = 150

• N lines → o = 50 × N

x – Touches at the Edges

• Number of touches within the edge area required to trigger the reference

• Recommended value: 2 or 3

y – Touches in Active Area

• Number of touches allowed in the active area

• Recommended value: 0 (no touches)

Example

displaxservice --te2fnref 100 2 0

This triggers a new reference frame when:

• Two lines around all edges are monitored

• There are 2 touches at the edges

• There are 0 touches in the active area
