Stellaris® One-Day Workshop
Introduction
Welcome to the Texas Instruments Stellaris one-day workshop. This workshop has been
segmented in order for it to be presented in a variety of formats: lunch and learn style, half day
and full day.
If you are attending the lunch and learn format, this introductory presentation will be presented.
If you are attending a half-day format, you will also have the chance to get hands-on with Code
Composer Studio, and the LM3S3748 and LM3S8962 evaluation kits.
If you are attending the full-day presentation, your afternoon will be a series of in-depth
presentations and labs covering the USB, CAN and Ethernet peripherals.
Whichever format that you’re here for, welcome to the class … let’s get started!

Stellaris ARM® Cortex™- M3 Overview
What Is The ARM® Cortex™-M3?
The ARM Cortex family is comprised of three series
Š
ARM Cortex-A Series
Š
Š
Š
ARM Cortex-R Series
Š
Š
Š
Applications processors for complex OS and user applications.
Supports the ARM, Thumb and Thumb-2 instruction sets.

partner for
AR M Cortex
A8, R4, and
M3
ARM Cortex-M Series
Š
Š
Š

No Assembly Required
No Assembly Required
Cortex-M3 has complete hardware support for
interrupts
‹
Interrupt Service Routines (ISRs) are written in C/C++
Interrupt setup is easily done in C/C++
Š
Š
Š
Š
‹
No boot code ASM, no system configuration ASM
ARM7 compilers normally come with an ASM boot routine (in
object form) that does the setup.
For Cortex-M3, no boot routine is needed
Š
Š
Š
Cortex-M3 hardware loads the stack pointer from memory and the
initial PC from memory and enters as a normal C function.
User C/C++ code is all that is required.
Š

C/C++ array which contains the vectors (pointers to the C/C++
functions)

Communication ISRs (e.g. ENET, CAN)
Main application (foreground)
t
‹
Main application runs as foreground (base level)
Š
Š
Easy to write since no “factoring” – normal application or RTOS based
Can use PLC style state-machine poll loop safely: ISRs keep data available
‹
ISRs for Motor control are highest priority(ies)
‹
ISRs for communications below motor controls
‹
May use other priorities as needed

Š
PWM, ADCs, Timer(s), Fault (may be highest), Temp sensor, etc

Very fast interrupt response time, true nested interrupts, priority masking,
easy ISR setup all contribute to making an easy solution
Application uses priority masking vs. interrupt-disable if needs critical region
