three_d_scanner.ino

/*
  Arduino code to operate a 3D scanner  - a stepper motor spinning the platform with the object scanned,  trigering camera shutter and (optionally) an external flash regularly.
  Can be used with Canon DSLRs with Magic Lantern's FRSP (electronic shutter) mode, with an external flash. Confirmed to work with 50D and 6D. For 6D, the program mlv_dump from
  http://www.magiclantern.fm/forum/index.php?topic=10526.msg188558#msg188558 works well under Windows.

  Includes modified Adafruit PCD8544 library.
