Purpose of the Project

• An opportunity to work in a team environment
• Gain knowledge and learn basic skills of
  soldering
• Select a sensor and learn the characteristics of
  that sensor

• Modify a program that allows us to read the
  analog voltage of our sensor
• Apply the knowledge learned from the semester to
  complete the board

3
Goals

• Create a functioning board
• Create the circuit and interface the board with a
  sensor
• Combine the two boards where the lcd outputs the
  temperature
• To become familiar on how several aspects of
  engineering are brought together to form a useful
  system.

4
The Overall Process
Solder all components To the board
The Completed Circuit
5
Order of Soldering

• Surface mounted resistors and capacitors
• Slider switch, 5 volt input plus, voltage
  regulator, push button switch
• MSP430 Chip
• Led display unit
• JTAG connector

The Overall Process
Solder all components To the board
Programming the MSP430 chip to read HELLO
The Completed Circuit
8
MSP430 Chip

• A very fine-pitch chip
• The connect point to chip are numerous and close
  together
• 25 connect points on each side
• Each side is ½ inch
• Soldering was tedious

9
Programming the MSP430 Chip

• Used files from ECE 300 website and the software
  that came along with the kit
• Select to create a new project
• Clicked and used files named delay.c, demo.c, and
  lcd.c
• After opening the lcdDisplay and selecting f430p,
  the chip had been flashed
• HELLO now appeared across the screen

The Overall Process
Solder all components To the board
Programming the MSP430 chip to read HELLO
The Completed Circuit
Selecting the AD590 Temperature sensor
11
The AD590JH Temperature Sensor

• Linear Current Output
• Wide range of temperature -55ºC to 150ºC
• Two Terminal Device Voltage In/Current Out
• Wide Power Supply Range 4V to 30V
• Low Cost

12
The Overall Process
Solder all components To the board
Programming the MSP430 chip to read HELLO
The Completed Circuit
Selecting the AD590 Temperature sensor
Create another board to connect the Power
source and Sensor

15
The Overall Process
Solder all components To the board
Programming the MSP430 chip to read HELLO
The Completed Circuit
Selecting the AD590 Temperature sensor
Re-program chip using the sensor file
Create another board to connect the Power
source and Sensor
16
Interfacing the Sensor

• The board was able to display the sensor reading
  by using delay.c, lcd.c, and sensor.c
• The proper temperature was displayed by modifying
  sensor.c
• Correction factor was manipulated until output
  displayed correct temperature

The Overall Process
Solder all components To the board
Programming the MSP430 chip to read HELLO
Connect both boards to get desired temperature
The Completed Circuit
Selecting the AD590 Temperature sensor
Re-program chip using the sensor file
Create another board to connect the Power
source and Sensor

Troubleshooting

• Wired the DPDT switch wrong the circuit for the
  sensor was not getting any power
• The 1k ohms and 100 ohms potentiometer had to be
  adjusted to right setting
• 100 ohms set to 296.2 mV

22
What We Learned

• Soldering skills
• The MSP430 and AD590 temperature sensor
• Circuit Troubleshooting
• Teamwork
