ToolSt ick-CapTouchSenseDC
2. Contents
The ToolStick-CapTouchSenseDC kit contains the following items:
A ToolStick daughter card requires a ToolStick Base Adapter to communicate with the PC. ToolStick Base Adapters
can be purchased at www.silabs.com/toolstick. The ToolStick-CapTouchSenseDC is also available as part of a
ToolStick Starter Kit (CapTouchSenseSK) that includes a CapTouchSenseDC, Toolstick Base Adapter, and USB
Extension Cable and may be purchased from the same link.
3. ToolStick Overview
The purpose of the ToolStick is to provide a development and demonstration platform for Silicon Laboratories
microcontrollers and to demonstrate the Silicon Laboratories software tools, including the Integrated Development
Environment (IDE).
The ToolStick development platform consists of two components: the ToolStick Base Adapter and a daughter card.
The ToolStick Base Adapter provides a USB debug interface and data communications path between a Windows
PC and a target microcontroller.
The target microcontroller and application circuitry are located on the daughter card. Some daughter cards, such
as the CapTouchSense Daughter Card, are used to demonstrate a specific feature or application and some are
used as general-purpose development platforms for the target microcontrollers.
The CapTouchSense Daughter Card includes a C8051F931 MCU, four GPIO controlled LEDs, a switch connected
to a GPIO, four capacitive touch sense switches, and a small prototyping area which provides access to all of the
pins of the device. This prototyping area can be used to connect additional hardware to the microcontroller and use
the daughter card as a development platform. The CapTouchSense Daughter Card also includes an A76 1.5 V
alkaline battery which can be used to power the board when not connected to the Toolstick Base Adapter. The
C8051F931 MCU on this daughter card will continue to operate from the single “button cell” battery until the supply
voltage drops below 0.9 V.
Figure 3 shows the ToolStick CapTouchSense Daughter Card and identifies the various components.
