2Install Software
and Tools
Install the OpenSDA Tower Toolkit to install
the OpenSDA and USB-to-Serial drivers.
3Configure the
Hardware
Connect one end of the USB cable to
the PC and the other end to the Power/
OpenSDA mini-B connector (J14) on the
TWR-KM34Z50M board. Allow the PC
to automatically configure the USB drivers
if needed.
4Segment
LCD
All segments are turned on for three
seconds, then potentiometer readings are
displayed. The LEDs should be blinking.
5Move the
Potentiometer
The onboard LCD shows the SAR-ADC
reading.
