Detailed Description

To work with Deepsy Gpio Manager service it is necessary to use GpioManager located in GMV.ITS.HAL.DEEPSY.Gpio.Facade for getting the initial GpioManager object.

GpioManager GpioManager = new GpioManager("");

GpioManager has an optional parameter indicating the ip address of remote service. For instance:

GpioManager GpioManager = new GpioManager("172.22.198.103");

GpioManager implements IDisposable. It can hold resources (such as socket handles) until it is disposed. The Dispose method is automatically called when existing a using or try / catch block, for which the object has been declared. This construction ensures prompt release, avoiding resource exhaustion exceptions and errors that may otherwise occur.

• * GpioManager GpioManager= null;
    try{
        GpioManager = new GpioManager("172.22.198.103");
        List<IGpio> gpios = GpioManager.GetGpios().ToList();
    } catch (Exception e) {
            throw e;
    } 
    GpioManager.Dispose();
