Appendix A - Smart-Frame Protocol Command Reference CARROLL TOUCH

A-32 Touch System Programmer’s Guide

Run_Diagnostics (3AH) (:)

Command Description

When the host sends the Run_Diagnostics (3AH) command, the touch

system executes all of the diagnostics tests that occur at power-up (such

as the RAM test, ROM test, and so forth) and generates an Error Report.

The touch system then resets the system defaults, just as if the power

had been turned off and then on again. The performance of these

diagnostics routines may take up to one second to complete.

Since the touch system defaults are reset, the host must send either the

Report_Transfer_On (44H) command or the Get_One_Report (46H)

command to the touch system so that the host can receive the Error

Report.

Report Format

See Get_Error_Report (32H) in this appendix for details of the Error

Report.
