SLAU213A Datasheet, PDF (7/19 Pages) Texas Instruments – MSP430FG4618/F2013 Experimenter’s Board

6. Functional Overview
This section contains information about the various on-board interfaces and their
functionality and about the various peripherals enabling these interfaces. Wireless
applications are facilitated using the MSP430’s capabilities to interface with the
Chipcon wireless evaluation modules (CCxxxxEMK) from Texas Instruments. The
on-board LEDs and LCD display are used for visual feedback. Audio applications
leveraging the MSP430FG4618’s full analog signal chain can be implemented
using the microphone and the audio output jack. In addition, communication
across components on and off the board has been integrated.
6.1 Interfaces
Some of these interfaces have the option of being inactive when not in use to
conserve power. This is made possible by MSP430 port pin configurations and/or
hardware jumpers on-board. Appendix B gives complete details of these jumper
configurations and their positions.
6.1.1 4-Mux LCD Display
The integrated SoftBaugh SBLCDA4 LCD display supports 4-MUX
operation and interfaces to the LCD driver peripheral of the
MSP430FG4618. More information on the LCD can be obtained from the
manufacturer’s datasheet.
6.1.2 Momentary-On Push Buttons
Two external push buttons, S1 and S2, are connected to the interrupt
capable MSP430FG4618 digital I/O port, P1.
6.1.3 Light Emitting Diodes (LEDs)
The experimenter board has a total of four LEDs, three connected to the
MSP430FG4618 and one connected to the MSP430F2013. The LEDs are
primarily used for display purposes. Two of the LEDs can be disconnected
using jumpers to reduce the overall power consumption of the board.
6.1.4 Buzzer
A buzzer is connected to a digital I/O port of the MSP430FG4618. It is
driven via a port pin of the MSP430. The buzzer can be completely
disconnected by using jumper JP1.
6.1.5 Single-Touch Sensing Interface
A capacitive touch sensing interface in the shape of a “4” is provided on-
board. This touchpad is connected to the digital I/O ports of the
MSP430F2013. A total of 16 individual segments form the touchpad, and
activity is monitored by the MSP430F2013. The resulting data is
communicated to the MSP430FG4618 via the MSP430 inter-
communication connections provided on-board.
