How to Install the Hardware

This section targets three main parts: the setup of the serial interface, the programming adapter, and the

power supply.

LCD and UVEPROM

The EVK is supplied with the LCD and a UVEPROM, separate from the EVK PCB. Install the EPROM and

LCD into the EVK PCB before proceeding. Refer to the STK/EVK target connectors section for the correct

LCD orientation. The STK has a one-time programmable (OTP) device mounted on the PCB.

Serial Communication

Connect the STK/EVK-PCB to the serial communications port of the PC using the 9-pin cable that is

supplied. Use the Settings/Communications. . .command to set the communication port to which the cable

is connected. The default selection is COM2.

The HyperTerminal (which uses the Terminal icon) is used to communicate to the STK/EVK MSP430 chip

via a Monitor Program that has already been downloaded into the EPROM of the chip. The HyperTerminal

settings used are: data bits—7; parity—even; stop bits—1; flow control—none.

Voltage Sources

The following four sources supply the voltage for the STK/EVK-PCB:

PC serial interface

Typically, the serial interface of the PC supplies the STK/EVK-PCB voltage using the 9-pin cable.

The user must determine if the serial interface can meet the electrical requirements of the

STK/EVK PCB. Some PC manufacturers do not source enough current and voltage from the

serial port to power the STK/EVK devices. If this is the case, a 9-volt battery can be connected in

parallel to the serial port.

3.6 V lithium battery

A battery can be assembled onto the STK/EVK that supplies the STK/EVK-PCB with power.

Programming Adapter

The Programming Adapter’s power supply is stabilized to 5 V (this can only be used on the EVK).

Target system

The power supply from a target system can be connected to the STK/EVK-PCB. A supply voltage

of 3 V to 5 V can be used.

CAUTION: Different Power Supplies

If there is more than one power supply connected, the STK/EVK is supplied

with the higher voltage, provided the data sheet supply voltage ranges are

not exceeded.

If the HyperTerminal program is running on the PC, the serial communication cable has been installed, the

proper com port is selected, and the proper voltage is supplied, the screen will look like Figure 1–3.
