CMSIS : Cortex Microcontroller Software Interface Standard
|
||||
==========================================================
|
||||
|
||||
Introduction
|
||||
~~~~~~~~~~~~
|
||||
CMSIS defines for a Cortex-M Microcontroller System:
|
||||
|
||||
* A common way to access peripheral registers and a
|
||||
common way to define exception vectors.
|
||||
* The register names of the Core Peripherals and the
|
||||
names of the Core Exception Vectors.
|
||||
* An device independent interface for RTOS Kernels
|
||||
including a debug channel.
|
||||
|
||||
By using CMSIS compliant software components, the user can
|
||||
easier re-use template code. CMSIS is intended to enable the
|
||||
combination of software components from multiple middleware
|
||||
vendors.
|
||||
|
||||
This project contains appropriate files for this MCU family
|
||||
taken from CMSIS. A full copy of the CMSIS files, together
|
||||
with additional information on CMSIS can be found at:
|
||||
|
||||
http://www.onarm.com/
|
||||
http://www.arm.com/
|
||||
|
||||
Documentation
|
||||
~~~~~~~~~~~~~
|
||||
The standard CMSIS documentation can be found within the
|
||||
Code Red IDE help system, via:
|
||||
|
||||
Help -> Help Contents -> Code Red Product Documentation -> CMSIS
|
||||
|
||||
More information on the use of CMSIS within the Code Red IDE
|
||||
can be found in the Support area of the Code Red website at
|
||||
|
||||
http://www.code-red-tech.com/
|
||||
|
||||
At the time of writing, the CMSIS FAQ can be found directly

History of updates to CMSISv2p00_LPC11xx
|
||||
========================================
|
||||
|
||||
2 June 2011
|
||||
-----------
|
||||
Updated version of core_cm0.h from ARM (V2.03, dated
|
||||
23. May 2011) - with main change being removal of
|
||||
core debug registers (which are not accessible from
|
||||
application code on Cortex-M0).
|
||||
|
||||
7 March 2011
|
||||
------------
|
||||
LPC11xx CMSIS 2.0 library project using ARM
|
||||
Cortex-M0 CMSIS files as supplied in ARM's CMSIS 2.0
|
||||
December 2010 release, together with device/board
|
||||
specific files from NXP (as previously supplied in
|
||||
CMSISv1p30_LPC11xx library project, dated 12 Jul 2010).
|
||||
|
||||
Note files are built -Os for both Debug and Release
