couldn't get the 266 EPD to work with the examples until I went back to GxEPD rather than GxEPD2.
Traced it back to GxEPD using the boards.h file - and from there to the correct pinouts to the 2.66 " epd -
motably - as per the schematics - which are correct - the Display is
MOSI 23 : correct
MISO 17 :
CLK 18 : correct
CS 5 : correct
RST : 16 WRONG -> 4
BUSY 4 WRONG -> 34
DC not shown - > 19 - - PIn 19 should be shown as used by the display and not available without due care
pin 17 Appears to have been unused - would have been good if it had been routed out instead of 19 , or used instead with the display.
see attatched modified diagram
the examples need to be adjusted to account for the different pinout also
