Reset Button
NOTE: Pins for the STK Demo Program
Some pins of the MSP430 device will be used for the sensor demo program (only available on
the STK):
• A5 (connected to the sensor)
• Seg0. . .Seg13 (connected to the LCD Display)
• Com1. . .Com4 (connected to the LCD Display)
• R03. . .R33 (connected to the LCD R-Ladder)
• P0.0 (connected to the Trigger button)
• The string MSP-STK430x320 should appear in the HyperTerminal window (white background
area of the STKW95 HyperTerminal window). In addition, the LCD display on the evaluation
board (EVK or STK) should display MSP430.
• If both do not appear, simply press the reset button on the evaluation board (identified with an
RES etched next to it) one time.
NOTE:
The MSP430 evaluation board requires very low supply voltages due to its ultra-low
power consumption characteristics. In this case, the RS232 interface, or a 3.6 V
lithium battery (if installed) provides the supply voltage for the STK/EVK.
Due to PC com port differences, it may be necessary to jumper the board down to
3 V or supply an external battery. To jumper the board, refer to the diagram in the
STK/EVK Target Connectors section, and place one jumper across the Vcc holes,
and another across the Vcc/LCD holes where the default for both of these is open.
