Add_Exit_Point_Modifier (29H) ())
Command Description
When the Add Exit Point modifier is enabled by sending the
Add_Exit_Point_Modifier (29H) command, the touch system sends an
Add Exit Point Coordinate Report when the stylus exits the touch active
area. This report is in addition to the Touch Coordinate Reports that are
sent for the currently selected touch mode. For example, if the touch
mode is sent to Enter Point Mode and the Add Exit Point modifier is
set, a Touch Coordinate Report is sent when the stylus enters the touch
active area and an Add Exit Point Coordinate Report is sent when the
stylus is removed from the touch active area. The touch system default
is Add Exit Point modifier disabled.
Report Format
The Add Exit Point Coordinate Report has the following format:
FD X Y FF
FD
= Start of Add Exit Point Coordinate report.
X
= X-axis logical touch coordinate.
Y
= Y-axis logical touch coordinate.
FF
= End of report.
Example
An example of an Add Exit Point Coordinate Report is:
FD 10 00 FF
It indicates that the center of the stylus exited at x coordinate 16 and at
y coordinate 0.
