2 Hardware Preparation

2.1. Remove the J3 connections on the LaunchPad to disconnect TXD, and

RXD from P1.1 and P1.2.

2.2. Remove the J5 connections on the LaunchPad to disconnect the

LaunchPad LEDs from P1.0 and P1.6.

2.3. Remove R34 and C24 on the LaunchPad to disconnect it from P1.3.

2.4. Use the MSP430G2211 device witch come from the LaunchPad

Development Kit and insert it in the LaunchPad MCU socket.

2.5. Connect the ITO Capacitive Sensor and the converter board to the

LaunchPad with proper orientation by ensuring that the “Kentec Display”

text are in the same direction as the text on the Launchpad.

2.6. Connect the LaunchPad with an USB cable to a PC.

NOTE: The 32-kHz crystal/oscillator on pins 12 and 13 is not required for the ITO Capacitive Sensor demo.

3 Software Preparation

Bellow attachment is the source code for the projects, compile and download it to the LaunchPad.

4 ITO Capacitive Touch BoosterPack Hardware

As shown in Figure 4 and Table 1, the ITO Capacitive Touch

BoosterPack is an advance capacitive touch application

example for the new MSP430G2xxx touch-sense enabled I/O

pins. The demo shows 5 touch button for HMI, In addition,

there are two LEDs on the board to give instant feedback to

user interaction.
