// GxEPD2_HelloWorld.ino by Jean-Marc Zingg

// see GxEPD2_wiring_examples.h for wiring suggestions and examples
// if you use a different wiring, you need to adapt the constructor parameters!

// uncomment next line to use class GFX of library GFX_Root instead of Adafruit_GFX
//#include <GFX.h>

#include <GxEPD2_BW.h>
#include <GxEPD2_3C.h>
#include <GxEPD2_7C.h>
#include <Fonts/FreeMonoBold9pt7b.h>

// select the display class and display driver class in the following file (new style):
//#include "GxEPD2_display_selection_new_style.h"

// or select the display constructor line in one of the following files (old style):
//#include "GxEPD2_display_selection.h"
//#include "GxEPD2_display_selection_added.h"

// alternately you can copy the constructor from GxEPD2_display_selection.h or GxEPD2_display_selection_added.h to here
// e.g. for Wemos D1 mini:
GxEPD2_3C<GxEPD2_290_C90c, GxEPD2_290_C90c::HEIGHT> display(GxEPD2_290_C90c(/*CS=5*/ 5, /*DC=*/ 17, /*RST=*/ 16, /*BUSY=*/ 4)); // GDEM029C90 128x296, SSD1680
