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.

KIT5 DSP detail

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.
