Define a non-listed board

This procedure explains how to define a non-listed board.

If the hV_List_Boards header file does not include the configuration of a main controller board, it needs to be defined.

  • Create a variable with the pins_t structure;

  • Set the pins of the connected GPIOs, or specify NOT_CONNECTED otherwise;

  • Mention this variable to the screen constructor.

const pins_t myBoard =
{
    .panelBusy = 11, ///< EXT3 and EXT3.1 pin 3 Red
    .panelDC = 12, ///< EXT3 and EXT3.1 pin 4 Orange
    .panelReset = 13, ///< EXT3 and EXT3.1 pin 5 Yellow
    .flashCS = 18, ///< EXT3 and EXT3.1 pin 8 Violet
    .panelCS = 19, ///< EXT3 and EXT3.1 pin 9 Grey
    .panelCSS = 39, ///< EXT3 and EXT3.1 pin 12 Grey2
    .flashCSS = 38, ///< EXT3 and EXT3.1 pin 20 Black2
    .touchInt = NOT_CONNECTED, ///< EXT3-Touch pin 3 Red
    .touchReset = NOT_CONNECTED, ///< EXT3-Touch pin 4 Orange
    .panelPower = NOT_CONNECTED, ///< Optional power circuit
    .cardCS = NOT_CONNECTED, ///< Separate SD-card board
    .cardDetect = NOT_CONNECTED, ///< Separate SD-card board
};

Screen_EPD_EXT3_Fast myScreen(eScreen_EPD_271_PS_09, myBoard);

The EXT3 and EXT3.1 extension boards share the same first ten pins. The other pins are specific.
