8. Using the C8051F530 Daughter Card as a Development Platform
The prototyping area on the ToolStick C8051F530 daughter card makes it easy to interface to external hardware.
All of the digital I/O pins are available so it possible to create a complete system.
8.1. C8051F530 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 C8051F530 that are connected to other
components:
See the daughter card schematic in Section 10 for more information.
8.2. VREF Capacitor
On the C8051F530 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. 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 C8051F530, 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 P0.6 pins to be
used normally while simultaneously debugging the device. See Application Note “AN124: Pin Sharing Techniques
for the C2 Interface” at
9. Information Locations
Example source code is installed by default in the “C:\SiLabs\MCU\ToolStick\LINDC\Firmware” directory during the
ToolStick installation.
Documentation for the ToolStick kit can be found in the C:\SiLabs\MCU\ToolStick\Documentation\ directory.
The installer for the ToolStick software is available at www.silabs.com/toolstick.

P0.0, P0.1—These pins are connected to the LIN transceiver (U2).
P0.3, P0.4, P0.5—These pins are connected directly to the ToolStick Base Adapter for UART communication.
P1.1, P1.2—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 to output pin or handshaking pins could affect signaling.
