AN957: TouchXpress™ Configuration and Profiling Guide
Simplicity Studio Tools
2.4 Other Programming Options
Xpress Configurator produces an Intel hex image that contains the configuration profile. This hex image can be accessed by expanding
the configurator project in the Project Explorer, which can be accessed by clicking [Window]>[Show View]>[Project Explorer].
Once the project being configured is expanded, a file list appears that includes a .document file and a .hex image. Right-clicking on
the hex image and selecting [Browse Files Here] will take the user to the directory containing that hex image. This image can be pro-
grammed into TouchXpress devices using Simplicity Studio's [Flash Programming] utility, or through a command-line utility using the
Silicon Labs programming DLL.
To order pre-programmed devices from Silicon Labs, click the [Request Parts] button in [Xpress Configurator] and fill out the required
information. Then, click [Confirm and Send].
2.5 TouchXpress Program and Communication Interface
TouchXpress devices provide a two-wire interface that is used for both configuration profile programming and real-time data reads.
Connecting a ToolStick Debug Adapter to the Config Data and Config Clk pins on a TouchXpress device creates a link between the
device and Simplicity Studio. A ToolStick Debug Adapter is included on the TouchXpress evaluation boards to fascilitate configuration
and programming with the evaluation system. Stand-alone ToolStick Debug Adapters are also available to test devices in-system
(www.silabs.com/toolstick).
2.6 Example Xpress Configurator and Capacitive Sense Profiler Usage
The short example in this section illustrates how [Xpress Configurator] and [Capacitive Sense Profiler] can be used together to con-
figure and tweak the settings of a TouchXpress device. In this demonstration, a device using a 1/8th inch acrylic overlay will be tuned
for optimal performance.
