Macro Definition Documentation

◆ USE_LOCAL_FONT

#define USE_LOCAL_FONT   1

Set to 1 (default) to enable local font in this library and enable loadChar() and related methods. If the library is just used for graphics some FLASH RAM can be saved by not including the code to process font data. The font file is stored in PROGMEM.
