update

wayland/x27-589-gauge/update

Asynchronous non-blocking update of gauge. It does NOT move the motor to the target position, it advances the motor at most just one step toward the target position. Send a pulse to UPD as often as possible. The advantage of this node over the update-blocking node is that you can control many gauges simultanously, and you wont have long periods of inactivity (and potentially missed I/O events) while your motor is moving.

To use the node in your project you should have the wayland/x27-589-gauge 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 `SwitecX25` class instance
        auto gauge = getValue<input_DEV>(ctx);
        gauge -> update();
    }
