Firmware Commands

Developers may use this information when writing touch applications, developing custom

drivers or touch configurations, or testing their touch systems. Developers can use

firmware commands to initialize the controller, select operating modes, specify data

formats, and execute diagnostic functions.

Caution: This document assumes you are familiar with firmware commands and how to

use them. Executing some commands may alter the performance of your touch system

and render it inoperable. You should be aware of the results before executing any

firmware commands.

To optimize the performance of the touch controller and simplify the development of

custom drivers, 3M Touch Systems recommends you use the commands listed in Table

18 for current development. Using these commands ensures compatibility with all 3M™

controllers.

Note: When you enter commands in terminal mode, precede each command with

<CTRL> A to enter the start of header.
