MSP430-Hxxx-E HEADER BOARD
FOR MSP430F14x and MSP430F41x MICROCONTROLLERS
Fetures:
MSP430-Hxxx-E header board provides easy
way for developing and prototyping with
MSP430F14x
and
MSP430F41x
microcontrollers. The board is with following
features:
- JTAG connector
- JTAG Power_In and Power_Out jumpers
- 32768 Hz crystal oscillator
- Optional high frequency crystal
- RST/NMI pin pull-up
- Analog-Digital GND jumper
- Analog-Digital VCC jumper
- Power supply filter capacitors
- 0.1” (2.54 mm) extension slots
Power Out jumper:
Power_Out jumper connects power from Header
board to JTAG connector. When this jumper cap
is placed, the power supply of JTAG connector
will follow the power supply of Header board.
This is useful when your Header board (target
circuit) works at lower than +3,3V power supply.
Note:
Power_In
and
Power_Out
jumper caps should
not be placed at the same time.
Programming:
To program MSP430-1121STK you need
MSP430 JTAG dongle (Olimex part # MSP430-
JTAG) and MSP430 KickStart software.
KickStart allow you to write and debug code in
assembly language without any limitations and
to write code in C with 2K limit. The latest
release of KickStart software may be free

JTAG interface:
The JTAG connector is 2x7 pin with 0,1" step
and TI recommended JTAG layout. The PIN.1 is
marked with square pad on bottom and arrow on
top. JTAG signals are on port P1.4, P1.5, P1.6
and P1.7, which are not used for other functions.

Power In jumper:
Power_In jumper connects power supply from
JTAG connector to Header board. When this
jumper cap is placed you can program the
microcontroller even without any other external
supply. Note that if the Header board is placed in
target circuit, you have to ensure that your circuit
doesn't draw more than few milliampers current
or the power supply may decrease due to the
JTAG port current limitations. Power_In is
useful and must be used mostly to program your
header board when it's not put on your target
circuit socket.
