Targus RemoteTunes for iPod

Targus RemoteTunes for iPod

This is the Targus RemoteTunes(tm) for iPod. I got it from XSCargo, where they currently have them available for CDN$9.99.

Its guts include a transmitter and receiver pair. Even considering I don’t have an iPod to use this with, for $10.. I’m not arguing.

The receiver has:

The transmitter has:

The receiver and transmitter both have some unused pins on them:

Receiver (Base):

  • J: ICSP Data 
  • C: ICSP Clock
  • V: VPP / !MCLR
  • G: Ground
  • +: 3.3V from iPod

    PIC Pins:

  1. Power (Vcc = 3.3V)
  2. ?
  3. (Something to do with the output jack)
  4. VPP (Programming Voltage) / !MCLR (Reset)
  5. Data (From HiMark Pin 8)
  6. ICSP Clock
  7. ICSP Data / Serial Transmit
  8. Ground

    HiMark Pins: (Pages 11-12 of Datasheet. Pins I especially care about are un-italicized.)

  1. Oscillator 2 (From Tunable Coil)
  2. IF filter output
  3. Comparator input A
  4. Comparator input B
  5. Comparator offset adjustment
  6. Ground
