LiveQ

This is an advanced dsPIC project which interfaces an RDS/RBDS tuner chip and gets station info and text. TMC (traffic message channel) is decoded.

  • TMC (up to 120 messages) or RDS/RBDS data are shown:
    • onto an RGB OLED with a local road map (see picture on the right.)
    • via terminal through RS232-1 (no OLED needed.)

     

  • User menu control via joystick:
    • NAV/TUN/SET mode (long enter)
    • station preset  (short enter in TUN mode)
    • volume (up/down in TUN mode)
    • tune seek (left/right in TUN mode)
    • TMC city/area list (short enter in NAV mode)
    • area navigation (left/right/up/down in NAV mode)
  • User control via terminal (RS232-2 serial com port:)
    • tune up/down
    • station preset
    • show current frequency
    • show rds info
    • show active tmc messages

     

  • Countries supported for TMC NAV+TUN, road map view: Germany, France, Netherlands, Belgium.
  • Countries supported for TMC TUN, text view: Germany, France, Netherlands, Belgium, Sweden.

  • Assembled and programmed pcb.
  • Battery supply +3V5 ... +6V, integrated voltage regulator.
  • ON/OFF with single pushbutton.
  • Bootloader support.
  • Hardware is compatible with other omniboard projects and can be upgraded.
  • RGB 160x128 OLED and TMC memory card to be bought separately.

How to make it work?

  1. Use a supply or battery between +3V5 ... +6V max.
  2. Optional terminal through RS232-2 @ 115200 bpS, 8N1, "type comm"
  3. Connect an antenna (a simple wire will do, length best at 1,20m but may be less)
  4. Control settings via user menu (micro joystick) or terminal:
  • User menu control via joystick:
    • NAV/TUN/SET mode (long enter)
    • station preset  (short enter in TUN mode)
    • volume (up/down in TUN mode)
    • tune seek (left/right in TUN mode)
    • TMC city/area list (short enter in NAV mode)
    • area navigation (left/right/up/down in NAV mode)
  • User control via terminal connection (RS232-2 to pc serial com port:)
    • tune up: fru<CR>
    • tune down: frd<CR>
    • station preset: sfr<CR>
    • show current frequency: cfr<CR>
    • show rds info: rds<CR>
    • show active tmc messages: tmc<CR>
 

 

 

 

 

 

In case you need to reprogram the dsPIC from scratch, then use the ICSP+ connector X3, connected to a hardware programmer, like the dsPIC USB programmer: WinPic800.

Omniboard ICSP+ (X3 connector) connection pins:

  1. !MCLR/VPP
  2. PGD (data)
  3. GND
  4. PGC (clock)
  5. +3v3
  6. leave open
  7. leave open
  8. leave open (closest to pcb corner)

Omniboard RS232-2 (X1 connector) connection pins:

    1. +3v3 (closest to T2 transistor "717")
    2. PIC TX
    3. GND
    4. PIC RX

RS232 terminal & bootloader.
