CARROLL TOUCH Appendix A - Smart-Frame Protocol Command Reference

Touch System Programmer’s Guide A-39

Tracking_Mode (26H) (&)

Command Description

When the touch mode is set to Tracking Mode by sending the

Tracking_Mode (26H) command, the touch system sends Touch

Coordinate Reports to the host as long as the stylus is moving in the

touch active area. The touch system tracks the stylus, sending Touch

Coordinate Reports to indicate the current stylus position as it moves

through the touch active area. The touch system stops sending Touch

Coordinate Reports when the stylus is stationary, and resumes sending

Touch Coordinate Reports if the stylus begins to move again.

Tracking Mode is fundamentally identical to Continuous Mode except

that the touch system does not send redundant Touch Coordinate

Reports when the stylus is stationary. Tracking Mode is used in

applications where cursor positioning is required, such as graphics

applications. Tracking Mode is the system default touch mode.

Report Format

See Coordinate Reporting (23H) in this appendix for the format of the

Touch Coordinate Report and Non-Contiguous Coordinate Report.

Example

See Coordinate Reporting (23H) in this appendix for examples of the

Touch Coordinate Report and Non-Contiguous Coordinate Report.
