KIT8: JPG Decoder (063)  
     
 

Reads out an SD(HC) card to decode jpg files:

 

  • jpg image is shown on an RGB OLED.
  • Both SD and SDHC up to 4GB are supported.
  • FAT (FAT16) and FAT32 support.
  • Fast 40MIPS DSP decoding.
  • Image decode time 0.5 .. 3 sec for normal quality.
  • User menu control via RS232/joystick. See details below.
 
  • The 4 most common jpeg compression formats are supported:
  • Jpeg type 1: 4:4:4 No Subsampling YCbCr for best possible quality.
  • Type 2: 4:2:2 Vertically subsampled Y1Y2CbCr, the most common format.
  • Type 3: 4:2:2 Horizontally subsampled Y1Y2CbCr, (rotated type 2)
  • Type 4: 4;2;0 vert. and hor. subsampled Y1Y2Y3Y4CbCr for highest compression.

KIT3:  LiveQ, RDS/RBDS TMC receiver (054)  
     
 

 

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:

     

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

KIT2: JPEG camera recorder (053)  
     
 

It interfaces a miniature C328 serial JPEG camera:

  • image preview is shown on an RGB OLED.
  • captured JPEG images are written to an onboard SD card.
  • User control via joystick. Image preview can be shown on an RGB OLED.
  • captured JPEG images may be written to a MMC or SD card.
  • User menu control via RS232/joystick. Bootloader support.
  • Hardware is compatible with other omniboard projects and can be upgraded.
  • RGB 160x128 OLED and serial camera to be bought separately

 

  • 7 user selectable operation modes:
  • mode 1: 160x120 8-bit greyscale uncompressed to OLED.
  • mode 2: (default mode) 160x120 16-bit (565) RGB uncompressed to OLED.
  • mode 3:  640x480 JPEG YCbCr 4:2:2 compressed to RS232 (terminal screen.)
  • mode 4: 640x480 JPEG YCbCr 4:2:2 compressed stored to SD card.
  • mode 5: Four sequencial 80x60 8-bit greyscale previews: Quad-split OLED
  • mode 6: 160x120 8-bit greyscale preview.
  • mode 7: module and interface are both idle.

KIT1: "hello world" (t01)  
     
  This is the easiest way to start playing with the OmniBoard.

KIT1 is a dsPIC beginners project which shows how to get the DSP going at 40MIPS. The "hello world" example outputs some text to the RS232 port.

  • Assembled and programmed pcb.
  • Battery supply +3V5 ... +6V, integrated voltage regulator.
  • ON/OFF with single pushbutton.
  • Free schematics, diagrams, software and source code downloads.
  • Bootloader support.
  • Hardware is compatible with other omniboard projects and can be upgraded.
