shiftlight

An Arduino-based shift light using Adafruit's NeoPixel strip

v2 now allows live editing of configuration variables

Display segments:

• dot
  • a single dot
• bar
  • a growing bar
• wipe
  • either a solid bar, a new growing bar, or a wipe from the "bar" color (grow/wipe are from the rpm for "wipe" to the rpm for "shift")
• shift
  • a flashing bar

User Interface (implemented with a pushbutton encoder):

• in RUN mode:

  • holding button enters SET mode
  • turning knob adjusts brightness
    • pressing button during brightness display saves the brightness setting
    • waiting for timeout retains but does not save the brightness setting
  • tapping button toggles RUN/STOP modes

• in SET mode:

  • holding button enters ADJUST mode
  • turning knob adjusts which of the five sets of parameters is active
    • pressing button during the color display saves the current parameter set
  • tapping button saves current parameter set
  • waiting for timeout retains but does not save the parameters

• in ADJUST mode:

  • holding button saves parameters and returns to RUN mode
  • turning knob adjusts the current parameter (color, rpm, wipe mode, or brake light)
  • tapping button moves to the next parameter (and will cycle back)
    • first is the color for a segment, shown when exceeding the rpm for the segment
    • next is the rpm for the segment, displaying in two 4-bit digits representing the thousands (red) and hundreds (blue) places, so 7800 rpm is displayed as these lights: (0111 1000)
    • after all four segments (dot, bar, wipe, shift), the next two parameters are wipe mode and the brake light
    • for wipe mode, choices are solid (flashing), grow (oscillating w/ bar segment blank), or wipe (oscillating)
    • for brake light, the brake light will be displayed when it will illuminate during the shift period
  • waiting for timeout retains but does not save the parameters
