• Porting our original indicator project to Atmel family controller and changing some of the fundemental operation of how the input is done and also making the display bi-color and in essence its 3 colors.
  The original design relied on too many connections between the controller and display it self, 12 for the display and 9 for selector for 6 speed manual transmission. The count would be less for say 5 speed or automatic transmissions.
  
  In this design, display had been separated onto its own pcb board which contains some logic chips to drive the LEDs and a processor board containing naturally the processor, voltage regulator and sensors/switches connections. Additionally inputs are triggered by grounding it rather then connecting to the matrix logic making it safer triggers and possibly avoiding damaging the processor or display or incorrect wiring
  
  
  Display
  The kit requires 3 boards from our box of parts
     A 5x7 bi-color display board
     A custom board with shift registers and logic drivers for selection of particular color
     Lastly, acustom processor board with power supply and connectors to sensors and display board
  
  The display will need to be assembled by soldering the display LED board on back of the shifr register doard. Depending on version of the LED board , some will be casolated edges and some may not. For casolated edges its simple just place back to back and solder on the edges. For non casolated boards we can trim off part of the edges or leave the display board untouched but solder paste will be required. Best way around it is to dispense a small amount of solder paste on the pads and gently heat up the holes thus melting the paste.  The displays have symetrical pin layout meaning you can turn them around and they will still function with one cavid is that the color orientation will change. This can be easily changed in the software if needed and if you do not like they way colors are shown for each digit.
  Secondly, currently the shift register boards where designed to fit into our custom shift knobs. We will be producing boards with mounting holes in the future.
  
  A small 6 pin connector from the shift register board connects it to the processor board

  Software
  Sample software below controls the display and reads sensors. changing character patterns in  const byte N_DATA[NUM_ROWS]  blocks controls whats character and color is displayed.
  This is a pattern of N
  B01010001, // Row 1: * *
  B01011001, // Row 2: ** *
  B01010101, // Row 3: * * *
  B01010011, // Row 4: * **
  B01010001, // Row 5: * *
  B01010001, // Row 6: * *
  B01010001 // Row 7: * *
  
  The MSB red 0 will select red color in red/greed led combination and pattern in yellow composes N
  Other blocks format other characters
  
  The provided sample code will automatically display N if no inputs are triggers and will scan and display first input from 1 or first character.
