C8051F064-EK
8. Example Source Code
Example source code and register definition files are provided in the “SiLabs\MCU\Examples\C8051F06x”
directory during IDE installation. These files may be used as a template for code development. Example
applications include a blinking LED example that configures the green LED on the evaluation board to blink at a
fixed rate.
8.1. Register Definition Files
Register definition files C8051F060.inc and C8051F060.h define all SFR registers and bit-addressable control/
status bits. They are installed into the “SiLabs\MCU\Examples\C8051F06x” directory during IDE installation. The
register and bit names are identical to those used in the C8051F06x data sheet. Both register definition files are
also installed in the default search path used by the Keil Software 8051 tools. Therefore, when using the Keil 8051
tools included with the evaluation kit (A51, C51), it is not necessary to copy a register definition file to each project’s
file directory.
8.2. Blinking LED Example
The example source files, blink.asm and blinky.c, show examples of several basic C8051F06x 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. When compiled/assembled and linked, this
program flashes the green LED on the evaluation board about five times a second using the interrupt handler with
a timer.
