Step-by-Step Installation Instructions

TWR-S12GN32 Features

In this Quick Start Guide, you will learn how to set up the

TWR-S12GN32 board and run the default exercise.

STEP

Using the

Example Project

The pre-loaded example utilizes the TWR-

S12GN32’s push button switches, serial

communicationsinterfaceandLEDs.

Oncetheboardispluggedinyoucan

controlthebankoffourLEDsbypushing

one of the four on-board push buttons

(SW1–4).Connecttheincludedserial

adaptertoJ8andstartaterminalinyour

computer(9600bauds,eightdatabits,

one stop bit, no parity). You should see

the keystrokes echoed by the device.
