6.2. Building and Downloading the Program for Debugging
1. Once all source files have been added to the target build, build the project by clicking on the Build/Make
Project button in the toolbar or selecting Project
Note: After the project has been built the first time, the Build/Make Project command will only build the
files that have been changed since the previous build. To rebuild all files and project dependencies, click
on the Rebuild All button in the toolbar or select Project
2. Before connecting to the target device, several connection options may need to be set. Open the
Connection Options window by selecting Options
the appropriate adapter in the "Serial Adapter" section. Next, the correct "Debug Interface" must be selected.
C8051F58x/59x family devices use the Silicon Labs 2-wire (C2) debug interface. Once all the selections are
made, click the OK button to close the window.
3. Click the Connect button in the toolbar or select Debug
4. Download the project to the target by clicking the Download Code button in the toolbar.
Note: To enable automatic downloading if the program build is successful, select Enable automatic
connect/download after build in the Project
the build process, the IDE will not attempt the download.
5. Save the project when finished with the debug session to preserve the current target build configuration,
editor settings, and the location of all open debug views. To save the project, select Project
ect As... from the menu. Create a new name for the project and click on Save.

7. Example Source Code

Example source code and register definition files are provided in the "SiLabs\MCU\Examples\C8051F58x_59x\"
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.
7.1. Register Definition Files
Register definition files C8051F580.inc and C8051F580_defs.h define all SFR registers and bit-addressable
control/status bits. A macro definition header file compiler_defs.h is also included, and is required to be able to use
the C8051F580_defs.h
"SiLabs\MCU\Examples\C8051F58x_59x\Header_Files\" directory during IDE installation by default. The register
and bit names are identical to those used in the C8051F58x/59x data sheet. These 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.
7.2. Blinking LED Example
The example source
"SiLabs\MCU\Examples\C8051F58x_59x\Blinky" show examples of several basic C8051F580 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 on the C8051F580 Target Board about five times a second using the interrupt
handler with a C8051F580 timer.
