Table 6. Interrupt-driven driver files

File	Contains
main.c	Code example for the interrupt-driven driver.
OWIInterruptDriven.h	Configuration header file for the interrupt-driven driver.
OWIIntFunctions.c	Implementation of the interrupt-handlers and helper functions.
OWIIntFunctions.h	Header file for OWIIntFunctions.c.
source.doc	Documentation of the source code in this folder.

To get started with the interrupt-driven driver, follow the steps below:

•Create a new project in IAR embedded workbench. Depending on the version, this might require that a workspace is already created.

•Add all *.c files from the “polled” and “common_files” directories.

•Select the project from the project browser. Right click on the project and select options to bring up the project options dialog.

•Under “General/Target”, make sure that the correct device and memory model is selected.

•Under “General/Library configuration”, check the “Enable bit definitions in I/O include files” option.

•If AVRStudio is used for debugging, the output file format must be changed. Under XLINK/Output, select Format/Other, and then select “ubrof 8 (forced)” from the “Output format” drop-down box.

•Open the file “OWIInterruptDriven.h” for editing and locate the section named “User defines”.

•Change the defines in the “User defines” section to reflect the hardware setup.

•The project is now ready to be compiled.
