DEVKIT-S12G128
Features
The DEVKIT-S12G128
is an ultra-low-cost
development platform
for S12
Microcontrollers.
Features include easy
access to all MCU
I/O´s, a standard-
based form factor
compatible with the
Arduino™ pin layout,
providing a broad
range of expansion
board options, and an
USB serial port
interface for connection
to the IDE, the board
has option to be
powered via USB or an
external power supply.

Install Software and Tools
Install CodeWarrior Development
Studio for S12 V5.1 or later. CodeWarrior Dev Tools for HCS12(X)
MCUs
2
Connect the USB Cable
Connect one end of the USB cable to the PC and the other end to
the mini-B connector on the DEVKIT-S12G128 board. Allow the PC
to automatically configure the USB drivers if needed.
3
Using the Example Project
The pre-loaded example project utilizes the RGB LED. Once the
board is plugged in you can see how the RGB LEDs change the
color.
