// Some parts also mashed up from Graphic Library for driving monochrome displays based on the PCD8544,
// Copyright (c) 2011, Wim De Roeve, who in turn did partial port of code found on

//
// Changelog:
//   2011-08-25 - Initial release by Andrew Schamp <schamp@gmail.com>
//   2012-06-19 - Ported to mbed and optimised (WH)
//   2013-07-12 - Minor comment fix and placeholder for SSD1306 (WH)
//   2015-01-01 - Switch for optimised I2C calls to test on F401 (WH)
//   2017-12-18 - Fixed non-copyable issue (Thx kenjiArai)
