// purpose is e.g. to determine minimum code and ram use by this library
|
|
|
|
// see GxEPD2_wiring_examples.h of GxEPD2_Example 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, to use less code and ram
|
|
//#include <GFX.h>
|
|
|
|
#include <GxEPD2_BW.h> // including both doesn't use more code or ram
|
|
#include <GxEPD2_3C.h> // including both doesn't use more code or ram
|
|
#include <GxEPD2_7C.h> // same for all three

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

|
|
// alternately you can copy the constructor from GxEPD2_display_selection.h or GxEPD2_display_selection_added.h of GxEPD2_Example to here
|

// e.g. for Wemos D1 mini:
|
|
//GxEPD2_BW<GxEPD2_154_D67, GxEPD2_154_D67::HEIGHT> display(GxEPD2_154_D67(/*CS=D8*/ SS, /*DC=D3*/ 0, /*RST=D4*/ 2, /*BUSY=D2*/ 4)); // GDEH0154D67
