C8051F30x-DK
4.5. Example Source Code
Example source code and register definition files are provided in the “SiLabs\MCU\Examples\C8051F30x” directory
during IDE installation. These files may be used as a template for code development. Example applications include
a blinking LED example which configures the green LED on the target board to blink at a fixed rate.
4.6. Register Definition Files
Register definition files C8051F300.inc and C8051F300.h define all SFR registers and bit-addressable control/
status bits. They are installed into the “SiLabs\MCU\Examples\C8051F30x” directory during IDE installation. The
register and bit names are identical to those used in the C8051F30x 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 development kit (A51, C51), it is not necessary to copy a register definition file to each
project’s file directory.
4.7. Blinking LED Example
The example source files blink.asm and blinky.c show examples of several basic C8051F300 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 pro-
gram flashes the green LED on the C8051F300 target board about five times a second using the interrupt handler
with a C8051F300 timer.
