LAB 2: Migrate Quickly from 8-Bit To 32-Bit
Some of the toolkit applications capture and display data from the
DEMOQE128 board. The faster the PC is, the more rapid and smooth the
data display in these utilities will be.
Note that the above image is shown with the IN0 channel zoomed in. Each
analyzer channel has several features including the ability to be zoomed and
paused. For more information on DEMOQE Toolkit, see the board user
manual (DEMOQE128UM.pdf) included in the DVD under “DEMOQE128 >
DEMOQE128 User Manual” in the navigation panel on the left side of DVD
menu. For the latest DEMOQE Toolkit utilities, please visit http://

This lab will show you how to quickly migrate an application between the 8-bit
and 32-bit Flexis QE128 microcontrollers. The Flexis brand delivers pin-to-pin
compatibility, one development tool, and the same peripherals between the 8-
bit and 32-bit devices. This lab will demonstrate an upward migration from 8-
bit to 32-bit, but the opposite is just as simple. Continuing with the Quick Start
Application that is pre-loaded in the microcontroller’s on-chip flash memory,
you will now use the CodeWarrior MCU Change Wizard to retarget and
rebuild your project from the 8-bit to the 32-bit QE128 microcontroller.
