The internal signal that the circuit 100 of user's operation exports judges whether power key 200 receives the pressing operation of user, so as to really
Whether the unlatching for determining electronic equipment is to open by mistake to open, and then determines whether to close electronic equipment.For example, electronic equipment can pass through control
The internal signal of the Output pins output of the circuit 100 of the GPIO reading and savings user operation of device 600 processed, when electronic equipment is read
When getting the second internal signal (low level signal), it can be determined that go out input signal caused by power key 200 and believe for the second input
Number, i.e. power key 200 is not received by the pressing operation of user, and the unlatching of electronic equipment is opened to open by mistake, and can now pass through control
Device 600 processed closes electronic equipment.
For example, as user is to the quality requirement more and more higher of electronic equipment, before electronic equipment dispatches from the factory, it is necessary to make electronics
Equipment passes through various tests.In general, when electronic equipment is connected to test equipment by testing cable, electricity
Sub- equipment will be automatically turned on so as to be tested accordingly.
But electronic equipment can be pulled out and opened due to mispluging for test cable in some cases, at this moment due to not being to use
The intention at family and open, closing processing preferably is carried out to electronic equipment.
According to the exemplary embodiment of the present invention there is the electronic equipment for preserving the circuit that user operates can pass through guarantor
The circuit 100 for depositing user's operation utilizes battery voltage to pressing operation of the 300 record users to power key 200, so as to be set when electronics
After standby unlatching, the internal signal that the output of circuit 100 of user's operation preserves is preserved, when electronic equipment does not detect cable signal
When, electronic equipment can judge power supply by the internal signal that the circuit 100 of the reading and saving user of controller 600 operation preserves
Whether key 200 have received the pressing operation of user, and then determine whether this unlatching is to open by mistake to open, when it is determined that electronic equipment
Open when being opened to open by mistake, electronic equipment can be closed electronic equipment by controller 600.For example, controller 600 controls power supply
Power supply of the IC400 disconnections to each circuit unit in electronic equipment is managed, so as to close electronic equipment.
In addition, when electronic equipment detects cable signal, electronic equipment will not reading and saving user operation circuit
The internal signal of 100 outputs.Also, when electronic equipment is closed, electronic equipment will send low level signal by controller 600
To the Output pins for the circuit 100 for preserving user's operation, so as to remove the inside preserved in the circuit 100 for preserving user's operation
Signal, make circuit reset.
The circuit operated according to the preservation user for being used for electronic equipment of the present invention and the electronic equipment with the circuit,
Input signal caused by the button operation of user effectively can be saved as into internal signal, and the control of electronic equipment can be passed through
Device read internal signal, according to internal signal judge whether open or whether close electronic equipment, so as to effectively according to
The wish at family is turned on and off electronic equipment, enhances user and experiences effect to electronic equipment.
