3. ToolStick Overview
The purpose of the ToolStick is to provide a development and demonstration platform for Silicon Labs
microcontrollers and to demonstrate the Silicon Labs Simplicity Studio software tools.
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 C8051F850 Daughter Card, are used as general-purpose development platforms for the target
microcontrollers and some are used to demonstrate a specific feature or application.
The C8051F850 Daughter Card includes a pair of GPIO-controlled LEDs, a potentiometer, two switches connected
to GPIO, 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.
Figure 3 shows the ToolStick C8051F850 Daughter Card and identifies the various components.

11. Click the Close button.
5.5. ToolStick Terminal
The ToolStick Terminal program provides the standard terminal interface to the target microcontroller's UART.
However, instead of requiring the usual RS-232 and COM port connection, ToolStick Terminal uses the USB
interface of the ToolStick Base Adapter to provide the same functionality. The software is available on the ToolStick
webpage (www.silabs.com/toolstick).
In addition to the standard terminal functions (send file, receive file, change baud rate), two GPIO pins on the target
microcontroller can be controlled using the Terminal for either RTS/CTS handshaking or software-configurable
purposes.
To use the ToolStick Terminal program:
1. Download an example to the ToolStick device that uses UART communication. One example of this type is
the F85x-86x STDIO example in the UART folder from the Simplicity Studio example project creation
wizard.
2. Disconnect from the device in the Simplicity IDE. The IDE and the ToolStick Terminal cannot communicate
with the daughter card simultaneously.
3. Open ToolStick Terminal from the Start  Programs  Silicon Labs menu.
4. In the top, left-hand corner of the Terminal application, available devices are shown in the drop-down
Connection menu. Click Connect to connect to the device.
5. If using the F85x-86x STDIO example, text printed from the device will appear in the Receive Data
window.
6. Type in a value in the Transfer Data window and press the Send Data button. The firmware will echo the
value entered, print the value in hexidecimal, and prompt for a new value.
In addition to the standard two UART pins (TX and RX), there are two GPIO/UART handshaking pins on the
ToolStick Base Adapter that are connected to two port pins on the target microcontroller. ToolStick Terminal is used
to configure and read/write these pins. Under Pin State Configuration area in ToolStick Terminal, select the
8
Rev. 0.2
TOOLSTICK850DC-UG
desired state from the drop-down menu and click the Set Selected Pin States button.
The firmware on the C8051F850 target microcontroller does not need to be customized to use the UART and
communicate with ToolStick Terminal. The firmware on the microcontroller should write to the UART as it would in
any standard application, and all of the translation is handled by the ToolStick Base Adapter.
6. Using the C8051F850 Daughter Card as a Development Platform
The prototyping area on the ToolStick C8051F850 Daughter Card makes it easy to interface to external hardware.
All of the digital I/O pins are available, so it is possible to create a complete system.
6.1. C8051F850 Pin Connections
It is important to note that if external hardware is being added, some of the existing components on the board can
interfere with the signaling. The following is a list of port pins on the C8051F850 that are connected to other
components:

daughter card includes the resistors necessary to enable pin sharing, which allows the /RST and P2.0 pins to be
used normally while simultaneously debugging the device. See Application Note “AN124: Pin Sharing Techniques
for the C2 Interface” at www.silabs.com/products/mcu/Pages/ApplicationNotes.aspx for more information regarding
