IR Manager

IR Manager is an application that publishes Remote Key events to other applications. This manager receives IR signals from driver and dispatch it to all registered listeners on IARM Bus. IR manager sends these IR events to other applications.

IR Manager: Events

• IARM_BUS_IRMGR_EVENT_IRKEY
  The Event Data contains Key Code and Key Type of the pressed IR key. This enum is used to notify IR Key events.
  Example:

  IARM_Bus_IRMgr_EventData_t eventData;
  eventData.data.irkey.keyType = KET_KEYUP;
  eventData.data.irkey.keyCode = prevEventData.data.irkey.keyCode;
  IARM_Bus_BroadcastEvent(IARM_BUS_IRMGR_NAME, (IARM_EventId_t)IARM_BUS_IRMGR_EVENT_IRKEY,
                           (void *)&eventData, sizeof(eventData));

  
  
• IARM_BUS_RF4CEMGR_EVENT_KEY
  The RF4CE fetches the user key and that will pass to UEI's quickset application, that will then fetch the requested TV's IR codeset. UEI's fetch mechanism can be local or non local (Cloud based). Once the requested TV IR codeset has been retrieved , it will then be programmed into the remote via API calls. Ultimately, this will allow the XR device to control the following keys on a given TV. It support for the various keys such as OK, TV input, Volume UP, Volume Down, Mute Toggle power, Discrete Power ON, Discrete Power OFF, and so on.

  IARM_Bus_RegisterEventHandler(IARM_BUS_RF4CEMGR_NAME, IARM_BUS_RF4CEMGR_EVENT_KEY, _rf4ceEventHandler); //Register Callback func
  void _rf4ceEventHandler(const char *owner, IARM_EventId_t eventId, void *data, size_t len); //Function prototype

IR Manager: RPC Methods

IR manager publishes two RPC Methods such as SetRepeatKeyInterval and GetRepeatKeyInterval. Other application can invoke these methods to determine how often a repeat key is sent when the IR key is held own by the user.

• IARM_BUS_IRMGR_API_SetRepeatInterval
  This API is used to set the repeat key event interval.
  Example:

  IARM_Bus_IRMgr_SetRepeatInterval_Param_t param;
  param. timeout = 200; //200 milisec
  IARM_Bus_Call(IARM_BUS_IRMGR_NAME, IARM_BUS_IRMGR_API_SetRepeatInterval,
                (void *)&param, siizeof(param));

  
  
  
• IARM_BUS_IRMGR_API_GetRepeatInterval
  This is used to retrieves the current key repeat interval.
  Example:

  IARM_Bus_IRMgr_SetRepeatInterval_Param_t param;
  IARM_Bus_Call (IARM_BUS_IRMGR_NAME, IARM_BUS_IRMGR_API_GetRepeatInterval, \
                   (void *)&param, sizeof(param));

How to register callback function with HAL to receive the IR keys

This function must initialize all the IR specific user input device modules.

PLAT_API_RegisterIRKeyCallback(PLAT_IrKeyCallback_t func);

Callback prototype

The event data contains Key type and Key code of the pressed IR Key.

typedef void (*PLAT_IrKeyCallback_t)(int keyType, int keyCode);
