The C8051F370 ToolStick DC (TOOLSTICK370DC) kit contains the following item:
ToolStick C8051F370 Daughter Card
A ToolStick daughte r card requires a ToolStick Base Adapter to communicate with the PC. ToolStick Base Adapters
can be purchased separately at www.silabs.com/toolstick.
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 C8051F370 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 C8051F370 Daughter Card includes a pair of LEDs, a potentiometer, a resistor across the C8051F370’s
current DAC output pin, 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 har dwar e to th e micr ocontroller and u se the dau ghte r card a s a
development platform.
Figure 3 shows the ToolStick C8051F370 Daughter Card and identifies the various components.

5.4. 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, chang e baud rate), two GPIO pins on the t arget
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 TS F39x-37x FeaturesDemo example 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.
Open ToolStick Terminal from the
3.
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 TS F39x-37x FeaturesDemo example, text printed from the device will appear in the Receive
Data window.
6. Rotate the potentiometer on the board to change the blink rate or brightness of the LED.
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 conn ected to two po rt pins on th e target microcontroller. ToolStick Terminal is used
to configure and read/write these pins. Under Pin State Configuration area in ToolStick Terminal, select the
desired state from the drop-down menu and click the Set Selected Pin States button.
The firmware on the C8051F370 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 C8051F370 Daughter Card as a Development Platform
The prototyping area on the ToolStick C8051F370 daughter card ma kes it easy to interf ace to external hardware.
All of the digital I/O pins are available so it is possible to create a complete system.
6.1. C8051F370 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 C8051F370 that are connected to other
components:
P0.1 and P1.2—These pins each have a pull-down resistor (R7 and R9) to ground so that the IDAC0 and
IDAC1 output can be converted to a voltage. R7 and R9 can be safely removed from the daugh ter card if it
is not needed.
P0.4, P0.5—These pins are connected directly to the ToolStick Base Adapter for UART communication.
P0.6, P0.7—These pins are connected directly to the ToolStick Base Adapter’s GPIO pins. By default,
these GPIO pins on the Base Adapter are high-impedance pins so they will not affect any signaling.
Configuring these pins on the Base Adapter using the ToolStick Terminal to output pins or handshaking
pins could affect signaling.
P1.3—This pin is connected to the cathode of the green LED on the daughter card. The LED or the R2
resistor can be removed to disconnect the LED from the pin.
P1.6—This pin is connected to the output of the potentiometer. The 0 ohm resistor can be removed to
disconnect the potentiometer from the pin.
See the daughter card schematic in Section 7 for more information.
6.2. VREF Capacitor
On the C8051F370 devices, if VREF is generated internally, it is output to port pin P0.0. For VREF stability, it is
highly recommended to place a capacitor on the VREF output pin. On the ToolStick C8051F370 Daughter Card,
there are pads on the board (C1 ) to populate a 0603 surface mount capacitor. The firmware examples for the
daughter card use VDD as VREF, so no external capacitor on P0.0 is necessary for proper operation.
6.3. C2 Pin Sharing
On the C8051F370, the debug pins, C2CK, and C2D, are shared with the pins /RST and P2.0 respectively. The
daughter card includes the resistors necessary to enable pin sharing which allow 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 for more information regarding pin sharing.
