INTRODUCTION:
MOD-PULSE is an instrument for monitoring the blood oxygenation of a human. By measuring the oxygen level and heart rate, MOD-PULSE can display the levels of blood oxygenation and heart rate on it's LCD display. To perform it's func-tionality, MOD-PULSE requires external sensor connected to it via PROBE connect-or. MOD-PULSE can be connected to variety of OLIMEX's development boards via it's UEXT connector.
BOARD FEATURES:
• MCU: MSP430FG439
• JTAG
• UEXT
• custom LCD
• two user buttons
• two status leds
• power supply switch
• +3V lithium battery connector
• Battery connector for 2 x 1.5V AA batteries
• DB9 – Female connector
• System clock crystal
• extension pin holes for each microcontroller's ports
• FR-4, 1.5 mm, red soldermask, component print
• Dimensions: 134.6x101.6mm (5.3 x 4.0")
ELECTROSTATIC WARNING:
The MOD-PULSE board is shipped in protective anti-static packaging. The board must not be subject to high electrostatic potentials. General practice for working with static sensitive devices should be applied when working with this board.
BOARD USE REQUIREMENTS:
Cables: The cable you will need depends on the programmer/debugger you use. If you use MSP430-JTAG-TINY, MSP430-JTAG-TINY-V2, or MSP430-JTAG-ISO, you will need USB A-B cable. If you use MSP430-JTAG, you will need LPT cable.

POWER SUPPLY CIRCUIT:
MOD-PULSE can take power from:
–UEXT connector, when BAT/UEXT switch is in position UEXT. In this case the jumper P_OUT has to be closed.
–JTAG, when jumper P_IN is closed.
–+3V via BAT connector, when BAT/UEXT switch is in position BAT. In this case the jumper P_OUT has to be closed.
–+3V lithium battery via 3V-LI_BAT connector, when BAT/UEXT switch is in position BAT. In this case the jumper P_OUT has to be closed.
The programmed board power consumption is about 30 mA with all peripherals enabled. So, we recommend you to supply the board via BAT connector instead of 3V-LI_BAT connector.
RESET CIRCUIT:MOD-PULSE reset circuit includes R1 (100k), C1 (10nF), JTAG connector
pin 11 and MSP43FG439 pin 74 (RST/NMI).
CLOCK CIRCUIT:
Quartz crystal Q1 32.768 kHz is connected to MSP430FG439 pin 8 (XIN) and pin 9 (XOUT).
JUMPER DESCRIPTION:
P_INWhen this jumper is closed, the board is power supplied by the standard JTAG pin 2. This is only possible when the consumption of the board is not very high which is typically the case with MSP430 microcontrollers. If this jumper is open the board should be power supplied by another external source. This jumper and P_OUT should always be reversely open/closed, i.e. if P_IN is closed, P_OUT should be open and vice versa. Default state is opened.
P_OUTWhen this jumper is closed, the board is power supplied not by the JTAG but from external source. Then the JTAG has to synchronize with the working voltages which is done through this line. This is especially important when debugging with JTAG. This jumper and P_IN should always be reversely open/closed, i.e. if P_OUT is closed, P_IN should be open and vice versa.
Default state is closed.
Page 8
J1When jumper J1 is shorted in position 1-2, UEXT pin 3 is connected to MSP430FG439 pin 55 (P2.4/UTXD0) – signal “UTXD0”. When jumper J1 is shorted in position 2-3, UEXT pin 3 is connected to MSP430FG439 pin 54 (P2.5/URXD0) – signal “URXD0”.Default state is shorted in position 2-3.
J2When jumper J2 is shorted in position 1-2, UEXT pin 4 is connected to MSP430FG439 pin 54 (P2.5/URXD0) – signal “URXD0”. When
jumper J2 is shorted in position 2-3, UEXT pin 4 is connected to MSP430FG439 pin 55 (P2.4/UTXD0) – signal “UTXD0”.
Default state is shorted in position 2-3.
Depending on jumpers J1 and J2 configuration, the board can work in host, or in device mode. The default state of J1 and J2 is for device mode (shorted in position 2-3).
INPUT/OUTPUT:
Status led with name LED1 (red) connected to MSP430FG439 pin 67 (P1.0/TA0).
Status led with name LED2 (red) connected to MSP430FG439 pin 65 (P1.2/TA1).
User button with name SW1 connected to MSP430FG439 pin 59 (P2.0/TA2).
User button with name SW2 connected to MSP430FG439 pin 58 (P2.1/TB0).
Power supply switch with name BAT/UEXT – when in position BAT – the board is power supplied via +3V lithium battery, when is in position UEXT – the board is connected to other board with UEXT and is power supplied by the other board via UEXT connector.
