Documentation

Features

  • A timer that listens for shots, recording up to 200 shots in a string, for strings lasting into double-digit hours.
  • A review mode which displays the shot #, time, split time with previous shot.
    • Review mode can also display average split and rate of fire in shots/min
  • User configurable par times
    • Ability to toggle the par times on and off
    • Ability to set up to 10 additive par beep times
  • Setting for start delay, including: Random 1-4s, Random 2-6s, and 0-10 seconds
  • Setting for rate of fire - calculation can be configured to include the draw (time to first shot) or not
  • Setting for beep volume
  • Setting for sensitivity (with options that will work for dry fire)
  • Setting for echo rejection
  • Settings are preserved when the device is turned off (EEPROM)

Hardware

Known Issues

  • Enabling DEBUG with the present code results in OOM errors(too many DEBUG statements), particularly when editing par times, but possibly also when listening for shots.

Release History

[2.0.0] (https://github.com/hestenet/arduino-shot-timer/releases/tag/v.2.0.0) - EEPROM

The 2.x branch of Shot Timer stores its settings in EEPROM, and does not require an SD card interface for Arduino.

This release represents a major refactor of the code, with a few goals:

  • Compatibility with Arduino v.1.6.8
  • Replace libraries with ones easily available in the Arduino->Sketch->Include Libraries interface
    • <MenuSystem.h> replaces <MenuBackend.h>
    • <Chrono.h> (specifically LightChrono) replaces <StopWatch.h>
    • <PGMWrap.h> has been added to help store strings and thus save dynamic memory
    • <EEWrap.h> has been added to improve EEPROM saving of settings
    • <Adafruit_RGBLCDShield.h> is unchanged
    • <Wire.h> is unchanged
    • <avr/pgmspace.h> is unchanged
    • <toneAC.h> is unchanged - and is now the only library from an external source: https://bitbucket.org/teckel12/arduino-toneac/
  • Pull some of my own functions into internal libraries
    • "DebugMacros.h" has been added to easily allow toggling of debug functions by commenting/uncommenting a single line
    • "Pitches.h" is unchanged
    • "LegibleTime.h" has been added to handle all functions of converting a time in millis(); to a legible string in format: 00:00:00.000 to a specified number of digits.
    • "LCDHelpers.h" has been added to handle printing data from PROGMEM to the LCD, printing legible time to the LCD, and printing numbers to a specified number of digits to the LCD
  • Reduce overhead
    • v.2.0.0: 17,652 bytes (54%) of PROGMEM and 1,467 bytes (71%) of SRAM (without DEBUG)
      • Note: The majority of this overhead is in the reservation of uint32_t shotTimes[200] (800 bytes) and in the reservation of uint32_t parTimes[10] (40 bytes) . Without these the program consumes 627 bytes (31%) of SRAM.

Deprecated Releases

1.0.0

Initial build, before the migration from code.google.com to github. There are some incompatibilities with the latest Arduino IDE version in the menuBackend library used in this branch.
