Summary of 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.

Most touch screen users do not have to use firmware commands to use their touch systems. For example, users can use TouchWare to calibrate the touch screen or to determine the controller type and firmware version.

Caution: This document assumes you are familiar with firmware commands and how to use them. Executing some commands alters the performance of your touch screen and can render it inoperable. You should be aware of the results before executing any firmware commands.

To optimize the performance of the EX II 3000SP touch screen controller and simplify the development of custom drivers, 3M Touch Systems recommends you use the commands listed in Table 3 for current development. Using these commands ensures compatibility with all 3M Touch Systems controllers.

Note: When you enter commands in terminal mode, precede each command with <CTRL> A to enter the start of header.
