About this Example
|
|
==================
|
|
This example demonstrates how to use the IAR EWARM IDE to build
|
|
a QP application.
|
|
|
|
|
|
IAR Project File
|
|
----------------
|
|
The IAR EWARM project file provided with this example uses relative paths
|
|
to the QP/C framework location (includes, port, and libraries. These
|
|
relative paths must be modified when the project is moved to different
|
|
relative location.
|
|
|
|
|
|
Stack Size and Heap Size
|
|
------------------------
|
|
In this project, the size of the C stack and heap are determined in
|
|
the linker script blinky-qk.icf (see the next section).
|
|
|
|
|
|
Linker Script
|
|
-------------
|
|
The IAR linker script provides a template of the recommended linker script
|
|
for QP applications. This file needs to be customized to set the
|
|
application-specific sizes of the Stack and Heap. This file can be edited
|
|
from the IAR EWARM IDE via the Project Options/Linker settings.
|
|
|
|
|
|
Startup Code
|
|
============
|
|
The startup code for the EFM32PG1B200F256GM48 MCU used in this project is
|
|
located in the "3rd_party" folder in the following location:
|
|
|
|
3rd_party\efm32pg1b\iar\startup_efm32pg1b.s
|
|
|
|
The file startup_efm32pg1b.s provides a template of the recommended
|
|
startup for QP applications and should be easily customizable for other
|
|
ARM Cortex-M microcontrollers.
|
|
|
|
The startup file typically does not need to be modified or adapted for
|
|
applications. It provides only weak definitions of all exception and
|
|
interrupt handlers, as well as the assert_failed() function.
|
|
|
|
The weak function assert_failed() defined in this file might be re-defined
|
|
in the application to customize it for the application-specific error-
|
|
handling policy.
|
|
|
|
***
|
|
NOTE: The function assert_failed() typically should NOT use the stack,
|
|
because stack might be corrupted by the time this function is called.
|
|
Also, assert_failed() is intended to handle catastrophic errors and
|
|
should NOT return.
