FRDM-K64F Code Share / Adafruit_358

This library can be used to control a low-cost Adafruit 358 TFT display. It has basic functionality but is a starting point for others trying to control this type of display using the FRDM-K64F.

bmazzeo 0:7cb96171f886 5 * A common base class for Text displays
bmazzeo 0:7cb96171f886 6 * To port a new display, derive from this class and implement
bmazzeo 0:7cb96171f886 7 * the constructor (setup the display), character (put a character
bmazzeo 0:7cb96171f886 8 * at a location), rows and columns (number of rows/cols) functions.
bmazzeo 0:7cb96171f886 9 * Everything else (locate, printf, putc, cls) will come for free
bmazzeo 0:7cb96171f886 10 *
bmazzeo 0:7cb96171f886 11 * The model is the display will wrap at the right and bottom, so you can
bmazzeo 0:7cb96171f886 12 * keep writing and will always get valid characters. The location is
bmazzeo 0:7cb96171f886 13 * maintained internally to the class to make this easy
