Division of Labor

• Aditya and Amjad will work solely on software issues– A/D Converter– Zigbee Communication

• Kirill – Mainboard Design– Hardware/Software Implementation

• Will also work with Aditya and Amjad, with software implementation of hardware (I.e. LCD, Keypad, RS-232, User Interface)

• Arush and Bilal – Sensors’ schematic and design– PCB for Main Board and Sensors

Development Kit•Our development kit came with a programming environment, CodeWarrior. The kit also came with demo applications to be tested with our board to introduce the user to programming for RF applications.

•The board has:

•Two accelerometers, four switches and LEDs, a MC13192 transceiver, printed antenna, serial interface and MC9s08GT60 low-power MCU with 60KB of flash memory.

Software

Aditya Kaundinya

Software Overview

Zigbee Communication• Simple Media Access Controller Functions•ANSI C based code used for developing RF applications.

A/D Converter Implementation• Used to convert continuous signals to digital numbers. •The digital output can take different arithmetic forms. (Binary, Hexadecimal, etc.)

Demo Software

• Our development kit came with demo code that allowed us to test our hardware.

• -Range Finder – Code that adjusted the number of blinking LED’s respective to the distance between the two boards.

• -UART Demo – Wireless transmits a user’s keystrokes to the terminal of another pc using the Zigbee transceivers.

Example Code (Range Detection)TRANSMIT STATE - case TX_STATE: /*Load the tx buffer with the ZigBee packet.*/ au8TxDataBuffer[0] = 'Z'; au8TxDataBuffer[1] = 'i'; au8TxDataBuffer[2] = 'g'; au8TxDataBuffer[3] = 'B'; au8TxDataBuffer[4] = 'e'; au8TxDataBuffer[5] = 'e'; sTxPacket.u8DataLength = 6; if (MCPSDataRequest(&sTxPacket) == SUCCESS) MLMERXEnableRequest(&sRxPacket,DELAY_COUNT);

RECEIVE STATE - case RX_STATE: MLMERXEnableRequest(&sRxPacket,0); break;

SMAC FunctionsMLMESetMC13192OutputAdjust

Adjusts the output power of the transmitter(0-15)

MLMEHibernateRequest Disables Clock Output

MLMEWakeRequest Brings radio out of low power mode

MLMERXEnableRequest Places radio in receive mode

sRxPacket->pu8Data[3] Reads power value from third byte of data packet

A-D Converter•Tire pressure sensor gives an analog voltage value.

• The output pin of the sensor is connected to one of the 8 A-D converter pins on the microcontroller.

•The voltage signal from the sensor is converted to a binary number using the microcontroller.

•The voltage-pressure relation below is used to convert the digital value into the corresponding pressure value.

Immediate Software GoalsGoal 1 – by 03/03/2008•Understand all the SMAC functions by next Monday.• Simultaneously work on writing code to control LED’s using the pushbuttons.Goal 2 – by 03/15/2008• Connect tire pressure sensor to the A/D converter on the development board.• Write software to output the correct air pressure from the A/D converter.

PCB Design and Logistics

Bilal Yousufi

PCB Design – Revision 1

• Altium Designer

• 1st Revision by March 1st

• R– 2 Boards

• Mainboard– Power Source: 12V Battery with DC-DC Buck Converter.

» Components Operate between 3.3V – 12V

• Tire Pressure Board

PCB Design – Revision 2

• 2nd Revision by Milestone 2– Mainboard– Tire Pressure, Temperature, 3-axis Accelerometer Board, and more if time permits

• Sensor Boards will be powered by batteries.– We will try to lower power consumption as much as possible– Test Power Consumption, based on transmission intervals

• Ruggedized Casing

– RF Data Modem

• 3rd Revision by Expo– More Sensors (Voltage or Fluid Level)– More Mainboard Functions

• Storage• Color LCD

• 4 Layer Boards from 4pcb.com– Routing on Outside– Inner Layers will be Voltage (3.3V) and Ground– A couple of Sensors use 5V, we might split the voltage layer, or use a boost converter.

Long Range RF Modem•Car – PC Link that can send Data (i.e. Racetrack, Test drive)

•40 Mile Range

•Monitor Sensor Data on Computer

•Will be implemented in the second revision of the design

•RS-232 Link (Already on Mainboard)

•Implementing Software will be the main issue

•We don’t have experience with creating packet structure

Power

• Mainboard– 3.3V, 5V– Input of 9V for 1st PCB Revision– Input of 12V for 2nd PCB Revision (Car Battery)

• Voltage Regulators to Step Down to 3.3V, and 5V• Boost Converter to 15 V

• Sensor– 3.3V Power Source– Converters for Sensor Chips

•Our first PCB Revision will not be wireless and have a 9V Source. We will be using the power adapters from our development kit.

•We will be using 9V with Voltage Regulators at 5V and 3.3V

•Our second PCB Revision will focus on power conservation, and the sensor modules will be run by batter
