This source comes from https://github.com/marcmerlin/NewLiquidCrystal Francisco gets all the credit for doing the original work of making a modular LiquidDisplay library. This code was forked off Francisco's code: http://hg.bijland.net/fmalpartida/new-liquidcrystal https://bitbucket.org/fmalpartida/new-liquidcrystal/wiki/Home In turn, Raron used Francisco's code and made this shift register library: http://code.google.com/p/arduinoshiftreglcd/ This is where I came in, by writing LiquidCrystal_SR_LCD3, was forked off LiquidCrystal_SR which unfortunately does not use the same wiring. I targetted the code for the Pebble and Pebblev2 (just released by freetronics in the arduino miniconf as part of linux.conf.au 2012) and therefore this code organizes the output data differently. Pinout for this code is used by all derivatives of the original LCD3Wire page: http://www.arduino.cc/playground/Code/LCD3wires This includes the LCA (linux.conf.au) Arduino Miniconf Pebble: http://shieldlist.org/luke-weston/pebble https://github.com/lukeweston/Pebble It also includes the Pebble v2: http://www.arduinominiconf.org/index.php/Pebble_V2.0_Instructions http://www.freetronics.com/pages/pebble-v2 https://github.com/lukeweston/pebble20/blob/master/README.md https://github.com/lukeweston/pebble20/blob/master/pebble-sch.pdf Pebbles and the LCD3Wires design are compatible hardware-wise, but the LCD3Wire code does not work with arduino 1.0 anymore and is generally quite limited in functionality compared to this framework that provides the entire LiquidDisplay functionality. Why write LiquidCrystal_SR_LCD3 and not just use the LiquidCrystal_SR pinout? - LCD3Wire was first and therefore have hardware that was designed with incompatible (IMO better if you don't mind 3 wires) pinout. - The pinout used here is same saner (the 4 bits for the LCD are all in one nibble of the shift register, not spread across 2 like in the LiquidCrystal_SR pinout) This code makes sure to properly follow the specifications when talking to the LCD while using minimal delays (it's faster than the LCD3wire and aiko pebble code).
