An exploded view of how the different boards connect

is shown in Figure A-3.

FIGURE A-3:

Board Connections.

A.2.1

PC PLATFORM

The Personal Computer (PC) shown in Figure A-2

needs to run on Windows® 98 SE or later. It provides a

convenient interface for the user, communicates with

the other boards, and provides power through the USB

connection.

A.2.2

PICkit™ 1 SIGNAL ANALYSIS PC

PROGRAM

The PICkit™ 1 Signal Analysis PC Program programs

the PIC16F684 PICmicro® microcontroller on the

Signal Analysis PICtail Daughter Board through the

USB port on the PICkit 1 Flash Starter Kit. It also

imports data through the same connection and displays

the data in Strip Chart, histogram, FFT plot and

oscilloscope plot formats. Data can be output in CSV

format for importing into a spreadsheet program.

A.2.3

PICkit 1 FLASH STARTER KIT

The PICkit 1 Flash Starter Kit (DV164101) programs

PICmicro microcontrollers. It uses the PIC16C745’s

USB port to communicate with the PICkit 1 Signal

Analysis PC Program. It connects to the Signal

Analysis PICtail Daughter Board via a header (see

Figure A-3).

This board provides a single +5V supply voltage for the

daughter boards. It can drive up to 5 µF on the supply;

a larger capacitance may interfere with program timing.

A.2.4

PICkit 1 FIRMWARE

This software resides on the PICkit 1 Flash Starter Kit’s

PIC16C745 microcontroller. Use version 2.0.2 or later.

A.2.5

SIGNAL ANALYSIS PICtail

DAUGHTER BOARD

This board is Microchip Development Tool AC164120.

It connects to the PICkit 1 Flash Starter Kit, which it

uses for both power and as a communications link to

the PC. The on-board PIC16F684 has a 10-bit ADC

that converts the Thermistor PGA PICtail Daughter

Board’s output voltage. The results are temporarily

stored on the board’s 25LC640 serial EEPROM chips.

The +5V single-supply voltage from the PICkit 1 Flash

Starter Kit board is bypassed with a bulk 1 µF capacitor

and local 0.1 µF capacitors for each IC.
