DEMOAC Labs
These labs will show you how to
get the most out of your DEMOAC
board toolkit. The DEMOAC
board comes in several versions
depending on the target AC family
MCU:
• DEMOS08AC16KIT

Learn How to Use the DEMOAC
Board Toolkit Utilities
This lab will show you how to use one of several
graphical utilities in the DEMOAC Board Toolkit
included with your board. Instructions to download
these utilities to your computer are provided in Step 2
of the Quick Start Guide (DEMOACQSG.pdf).
We will use the CodeWarrior IDE to program a
new software example into the AC256 and use the
DEMOAC Logic Analyzer utility. This PC-based utility
graphs the IN0 and IN1 signals on the board. For
convenience, if both DATA1 and DATA2 jumpers are
installed, IN0 graphs PTF2 activity and IN1 graphs
PTF3 activity. To graph other microcontroller signals,
use wire jumpers from the USB side of DATA1 and
DATA2 to the respective signals on the board’s MCU
PORT.

Migrate Quickly from 32-bit
to 8-bit Using the Quick Start
Application
This lab will show you how to quickly migrate any
application using the Flexis™ AC microcontrollers.
The Flexis brand delivers pin to pin compatibility,
one development tool, and the same peripherals
between 8-bit and 32-bit devices. It demonstrates an
downward migration from 32-bit to 8-bit, although
upward migration is just as simple. Continuing with

the microcontroller’s on-chip flash memory you will

Measure Performance
Improvement Between 8-bit and
32-bit with the Accelerometer
Application
This lab will highlight the performance differences
between the 8-bit and 32-bit AC microcontrollers and
show how these microcontrollers can easily interface
with a sensor. This lab will also detail how to use
another one of several software utilities included
with your board to help you in your development.
Instructions to download these utilities to your
computer were provided in Step 2 of the Quick
Start Guide.
The Accelerometer Application reads the X, Y, and
Z axes of the 3-axis accelerometer on the DEMOAC
board using the microcontroller’s A/D converter. It
outputs a processed version of the accelerometer data
on the microcontroller’s serial communication interface.
This processed data is a rolling average of the raw
accelerometer data,or a filtered version of the raw
accelerometer data, depending on the selected mode.
