7. Additional Demo Examples
In addition to the F336DC_FeaturesDemo example firmware, the ToolStick download package also includes demo
projects named F336DC_ADC0_TemperatureSensor and F336DC_IDA0_SineWave. The instructions for
running these demos can be found at the top of the source file.
The project and source files for these demos can be found in the C:\SiLabs\MCU\ToolStick\F336DC\Firmware\
folder.
8. Using the C8051F336 Daughter Card as a Development Platform
The prototyping area on the ToolStick C8051F336 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.
8.1. C8051F336 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 C8051F336 that are connected to other
components:
See the daughter card schematic in Section 10 for more information.
8.2. VREF Capacitor
On the C8051F336 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 C8051F336 Daughter Card,
there are pads on the board (C3) 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.
8.3. C2 Pin Sharing
On the C8051F336, 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
P0.1—This pin has a pull-down resistor (R7) to ground so that the IDAC output can be converted to a voltage.
R7 can be safely removed from the daughter 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.
