To use the node in your project you should have the wayland/wio-terminal-lcd library installed. Use the “File → Add Library” menu item in XOD IDE if you don’t have it yet. See Using libraries for more info.

C++ implementation

node {
    void evaluate(Context ctx) {
        // The node responds only if there is an input pulse
        if (!isInputDirty<input_UPD>(ctx))
            return;

        // Get a pointer to the `TFT_eSPI tft` class instance
        auto tft = getValue<input_DEV>(ctx);

        tft -> setRotation(getValue<input_Rotate>(ctx));

        emitValue<output_Done>(ctx, 1);
    }
