Dimmer Switch

The Dimmer Switch device is used to control a characteristic of a light (for example, luminance) and to switch the light device on and off.

The Device ID is 0x0104.
The header file for the device is dimmer_switch.h.
The clusters supported by the device are listed in Section 3.5.1.
The device structure, tsZLO_DimmerSwitchDevice, is listed in Section 3.5.2.
The endpoint registration function for the device, eZLO_RegisterDimmerSwitchEndPoint(), is detailed in Section 3.5.3.

Supported clusters

The clusters used by the Dimmer Switch device are listed in the table below.

Registration Function

The following eZLO_RegisterDimmerSwitchEndPoint() function is the endpoint registration function for a Dimmer Switch device.

teZCL_Status eZLO_RegisterDimmerSwitchEndPoint(
        uint8 u8EndPointIdentifier,
        tfpZCL_ZCLCallBackFunction cbCallBack,
        tsZLO_DimmerSwitchDevice *psDeviceInfo);

Description

This function is used to register an endpoint that supports a Dimmer Switch device. The function must be called after eZCL_Initialise().

The specified identifier for the endpoint is a number in the range 1 to 240 (endpoint 0 is reserved for ZigBee use). Application endpoints are normally numbered consecutively starting at 1. The specified number must be less than or equal to the value of ZLO_NUMBER_OF_ENDPOINTS defined in the zcl_options.h file, which represents the highest endpoint number used for application.

While invoking this function, specify a user-defined callback function, which is invoked when an event associated with the endpoint occurs. This callback function is defined according to the typedef:

typedef void(* tfpZCL_ZCLCallBackFunction)
(tsZCL_CallBackEvent *pCallBackEvent);

Also provide a pointer to a tsZLO_DimmerSwitchDevice structure, described in Section 3.5.2. This structure stores all variables relating to the color Controller device associated with the endpoint. The sEndPoint and sClusterInstance fields of this structure are set by this function and must not be directly written to by the application.

The function is called multiple times if more than one endpoint is being used - for example, if more than one Dimmer Switch device is housed in the same hardware, sharing the same module.

Parameters

u8EndPointIdentifier: Endpoint that is to be associated with the registered structure and callback function.
cbCallBack: Pointer to the function that is used to indicate events to the application for this endpoint.
psDeviceInfo: Pointer to the structure that acts as storage for all variables related to the device being registered on this endpoint (see Section 3.5.2). The sEndPoint and sClusterInstance fields are set by this register function for internal use and must not be written to by the application.
