This example demonstrates how to use the uVision IDE together with
|
|
the MDK-ARM toolchain.

uVision Project File
|
|
--------------------
|
|
The MDK-ARM uVision 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.

Support Code for EK-TM4C123GXL Board
|
|
====================================
|
|
The directory qpc\3rd_party\ek-tm4c123gxl contains the CMSIS-compliant
|
|
device code for the TM4C123GH6PM MCU (ARM Cortex-M4F). Please see the
|
|
README.txt file in this folder for more details.
|
|
|
|
Startup Code
|
|
------------
|
|
The startup file startup_TM4C123GH6PM.s provides a template
|
|
of the recommended startup for QP projects. The file needs
|
|
to be customized to adjust the stack/heap sizes and to implement
|
|
the product-specific error/assertion handling policy
|
|
in the assert_failed() function.
|
|
|
|
|
|
Adjusting Stack and Heap Sizes
|
|
==============================
|
|
The stack and heap sizes are determined in this project by the
|
|
command-line options for the ARM assembler (see the Asm tab in
|
|
the "Options for Target" dialog box in uVision). Specifically,
|
|
you should define symbols: Stack_Size=xxx Heap_Size=yyy, where
|
|
xxx represents a numerical value of stack size and yyy the
|
|
numerical value of the heap size.
|
|
|
|
***
|
|
NOTE:
|
|
C++ programs seem not to tolerate heap size of 0. Therefore it is
|
|
recommended to set the Heap_Size symbol to a minimal value of 16.
