FM Problems
Last Semester

• Designed three different milled boards
• Could not get assistance from Philips
• Using hand entered control data

6
FM Current Solutions
This Semester

• Fourth revision Professionally Made
• Using a commercial board as eval. board
• Created Assembly language parallel port control
  program

7
FM Current Status

• FM board receives and demodulates radio signals
  for a search function within the oscillator
  range.

8
Future Tasks

• Correctly Tuning local oscillators
• Verifying proper tuning range
• Evaluate need for EMI shielding

USB Problems
Last Semester

• Only one board was milled and populated
• Computer Recognition of an audio device was
  inconsistent
• I2C EEPROM unable to be programmed

11
USB Current Solutions
This Semester

• New board made and professionally printed
• Completely new test plan created
• Board is planned to have at least one more
  revision

12
USB Current Status
The USB board is being recognized by the PC
consistently. I2C EEPROM needed to store the
UDA1325 configuration map can successfully be
programmed. Creating a proper configuration map
that has all the initial settings is underway.
13
Future Tasks

• Complete Testing
• Programming EEPROM
• Sending command data to UDA1325

14
Software - Functions

• Tune to station
• Play audio signal
• Record audio signal to hard disk

15
Software Current Status

• DirectX parallel with Windows API
• Researching DirectX
• Can read and write to USB device via Windows API

16
Packaging

• PCBs with surface-mount technology
• Preliminary exterior packaging is being
  researched
