The pad can detect a pin of the male port of the flat keyboard, if both P L UG _ DET _ UP and P L UG _ DET _ Down of the pin of the male port are low level, it indicates that an extension device is inserted, then the pad can send a request for obtaining device information to a corresponding address of a bus, the teleconference speaker responds to the request, a self device ID (assumed to be DHHYYSQ011), a device version number, a manufacturer and other information can be carried in a response message, and after the pad obtains the device ID of the extension device, the extension device can be determined to be the teleconference speaker (abbreviated as DHHYYSQ).
The method includes that a pad can store service programs and application programs and the like required by starting a conference call loudspeaker in a pad storage space in advance, after the fact that an extension device is the conference call loudspeaker is determined, the pad can load a loudspeaker driver for the conference call loudspeaker, start corresponding service programs and application programs, send the programs required by starting the loudspeaker to the conference call loudspeaker, and after the conference call loudspeaker is started successfully, the pad reads the state of the conference call loudspeaker to complete state synchronization.
Therefore, the pad and the conference call loudspeaker can enter a normal working mode, and a user can use the pad and simultaneously improve the volume of a conference call through the conference call loudspeaker.
When a user needs to print a document for reading by people in a conference, a printer (corresponding to a female port of the printer) can be plugged in a male port of a conference call loudspeaker, an interface chip of the printer is also hung on an I2C bus, and information can be directly transmitted with a system of a pad.
The pad can detect a pin of the public port of the conference call speaker, if P L UG _ DET _ UP and P L UG _ DET _ Down of the pin of the public port are both low level, it indicates that an extended device is inserted, then the pad can send a request for obtaining device information to a corresponding address of a bus, the printer responds to the request and can carry information of own device ID (supposing DYJ080), device version number, manufacturer and the like in a response message, and after the pad obtains the device ID of the extended device, the extended device can be determined to be a printer (abbreviated as DYJ).
After determining that the extension device is a printer, the pad may download a service program, an application program and the like required for starting the printer from a network, load a printer driver for the printer, start the corresponding service program and application program, send the program required for starting the printer to the printer, and after the printer is successfully started, the pad reads the state of the printer to complete state synchronization.
Therefore, the pad and the printer can enter a normal working mode, and a user can use the pad and realize a document printing function through the printer.
