Software
On the main sketch, set the board to boardFeatherM0M4, corresponding to the pins defined in the hV_Configuration.h file of the ePaper_EXT3_Basic_Library (link 1, link 2).
NotesThis configuration is valid for other Feather variants, although some pins numbers may change.
Configurations are available for the Feather M4, Feather nRF52832, Feather nRF52840 and Feather RP2040. On the Feather RP2040, the I²C bus needs to be set to Wire1 to keep the same default SDA and SCL pins. |

Options
Large screens 9.7" and 12.2" require panelCSS to be defined and connected.
If the second memory is populated on the EXT3 board, flashCSS needs to be defined and connected. The library will keep flashCSS HIGH to avoid any interferences with the other devices connected to the SPI bus. |
