lib/LilyGo-EPD47-esp32s3/src/utilities.h does not compute...

[Starbane]

at least in my brain!

in file lib/LilyGo-EPD47-esp32s3/src/utilities.h where GPIO pins are mapped to defines the GPIO_NUM_48 is very popular indeed!

#define BUTTON_1   (48)
#define KEY_BTN  (48)

These I understand as aliases but

#define GPIO_SCLK  (48)

I have a bigger problem to grasp. For that matter I can not find any reference to any of:

#define GPIO_MISO  (45)
#define GPIO_MOSI  (10)
#define GPIO_SCLK  (48)
#define GPIO_CS    (39)

in the repo. Is the device equipped with a GPIO over SPI chip? It is a very elusive one if so.

Please at least advice...

Thanks in advance

Very sorry, these are some useless definitions, not deleted in time; The correct pin definition has been updated.
