Hardware Overview
This section contains information about the various onboard interfaces and their functionality and about
the various peripherals enabling these interfaces. Wireless applications are facilitated using the
capabilities of the MSP430 MCUs to interface with the wireless evaluation modules (CCxxxxEMK) from TI.
The onboard LEDs and LCD display give visual feedback. Audio applications that leverage the full analog
signal chain of the MSP430FG4618 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 port pin configurations on the MSP430 MCUs or hardware jumpers on the experimenter
board. For details of the jumper configurations and positions, see
Section 6.5.1
.
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
SoftBaugh website
.
6.1.2
Momentary-On Push Buttons
Two external push buttons (S1 and S2) connect to port P1, an interrupt-capable digital I/O port on the
MSP430FG4618.
6.1.3
Light Emitting Diodes (LEDs)
The experimenter board has four LEDs. Three connect to the MSP430FG4618, and one connects 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 connects to and is driven by a digital I/O port of the MSP430FG4618. The buzzer can be
disconnected by jumper JP1.
6.1.5
Single-Touch Sensing Interface
A capacitive touch sensing interface in the shape of a "4" is provided. This touchpad is connected to the
digital I/O ports of the MSP430F2013. A total of 16 individual segments form the touchpad, and the
MSP430F2013 monitors activity on the touchpad. The resulting data is communicated to the
MSP430FG4618 through the onboard MCU intercommunication connections.
6.2
Communication Peripherals
The experimenter board supports numerous communication interfaces for onboard and offboard
connections.
6.2.1
Wireless Evaluation Module Interface
Interface to the wireless world is accomplished through the wireless evaluation module header supporting
the CCxxxxEMK boards. The transceiver modules are connected to the USART of the MSP430FG4618
configured in SPI mode. For libraries that interface the MSP430 MCUs, visit the
CC2500 product page
.
The CC2420EMK (obsolete) supports the IEEE 802.15.4 and Zigbee standards. The CC1100EMK
(obsolete) supports an RF carrier frequency up to 868 MHz, and the CC2500EMK and CC2420EMK
support an RF carrier frequency of 2.4 GHz.
