1. Getting Started

Hardware
To set up the hardware for the CPT007B SLEXP8007A kit:
1. Provide power to the board by connecting the DBG USB connector to the PC using the provided USB cable. When a connection
has been established successfully, the LED (marked in the picture) lights up.
2. Place the acrylic overlay on the board over the capacitive sense pads.
Software
The first step to get started with your new CPT007B SLEXP8007A kit is to go to
http://www.silabs.com/simplicity
The Simplicity Studio software package contains all the tools, drivers, software examples, and documentation needed to use the
CPT007B Capacitive Sense Evaluation Board. The board comes preconfigured for a Touch Demo for use with the acrylic overlay. The
demo enables the board to recognize touch events and touch release events. Every time a touch is sensed, the paired digital output pin
will go high, the corresponding LED will light up, and the buzzer will sound.
After downloading the latest version of Simplicity Studio and installing the software:
1. The auto-detect feature in Simplicity Studio can cause a CPT device to miss touches. First disable automatic detection by clicking
the [Settings] icon, selecting [Device Manager]>[TCF Device Discovery], and selecting [Never] for [USB Discovery Options].
Click [OK].
2. Click the [Refresh detected hardware] button.
3. Select [CPT007B] under [Detected Hardware]. On the board, a successful USB connection is established when the LED next to
the USB connector turns on.
4. Click the [Capacitive Sense Profiler] tile. This utility graphs touch-related data and events received from the CPT007B
SLEXP8007A for evaluation and analysis.
