C8051F700-DK
5. Example Source Code
Example source code and register definition files are provided in the “SiLabs\MCU\Examples\C8051F70x_71x\”
directory during IDE installation. These files may be used as a template for code development. The comments in
each example file indicate which development tool chains were used when testing.
5.1. Register Definition Files
Register definition files C8051F70x.inc, C8051F70x_defs.h and compiler_defs.h define all SFR registers and bit-
addressable control/status bits. They are installed into the “SiLabs\MCU\Examples\C8051F70x_71x\” directory
during IDE installation. The register and bit names are identical to those used in the C8051F70x datasheet.
5.2. Blinking LED Example
The example source files
“SiLabs\MCU\Examples\C8051F70x_71x\Blinky” show examples of several basic C8051F700 functions. These
include disabling the watchdog timer (WDT), configuring the Port I/O crossbar, configuring a timer for an interrupt
routine, initializing the system clock, and configuring a GPIO port pin. When compiled/assembled and linked this
program flashes the green LED (DS3) on the C8051F700 Target Board about five times a second using the
interrupt handler with a C8051F700 timer.
5.3. Capacitive Sense Switch Example
The example source file F70x_CS0.c demonstrates the configuration and usage of the capacitive sense switches
located on P2.0 through P2.3. Refer to the source file for step-by-step instructions to build and test this example.
This is installed in the “SiLabs\MCU\Examples\C8051F70x_71x\ CS0\” directory by default.
5.4. QuickSense™ Firmware API Example
The
c:\Silabs\MCU\QuickSense_Studio\Kits\F700_TargetBoard. The firmware uses the QuickSense Firmware API to
measure capacitance on the sensing pads and application layer code adjusts the brightness of the target board’s
LED whenever the user presses a sensing pad. The firmware provides the following functionality:





6
Stores measured capacitance values from 4 sensor pads.
Compares measured capacitance values against calibrated thresholds to determine if buttons have been
pressed.
If a button’s “active” or “inactive” threshold has been crossed, the API signals an application layer routine
adjusts the brightness of the board’s LED.
Using the Serial Interface part of the QuickSense Firmware API , the firmware transmits measured capacitance
values across the CP210x USB-to-UART serial interface to the QuickSense development and display tools.
Baselining algorithm reduces effects of environmental changes such as temperature and humidity on sensing
pad sensitivity.
