An electronic device includes a storage unit, a pressing apparatus, a processing unit, and a button unit having a number of buttons. Identification (ID) information of each of the buttons and a predetermined signal corresponding to each of the buttons are stored in the storage unit. When a control signal is generated by the button unit after a button is pressed, the ID information of the button that is pressed is obtained from the storage unit. The control signal is compared with the corresponding predetermined signal to determine whether the pressed button is malfunctional.

An electronic device includes a storage and a processor. When the processor performs a data transmission process performed by the processor to transmit data to the storage, a time period duration of writing data into the storage is timed. An Acknowledge (ACK) signal indicating the data is successfully written into the storage is detected. If the ACK signal is not detected and the time period duration exceeds a predetermined time period, the processor restarts the data transmission process to re-transmit the data to the storage, to avoid system crash.

A test device for testing functions of buttons of a remote control includes a storage unit, a pressing apparatus, and a processing unit. Identification (ID) information of each of the buttons and a predetermined code corresponding to each of the buttons are stored in the storage unit. When a control signal is received from the remote control after a button is pressed, the control signal is decoded to obtain a code of the control signal and the ID information of the button, which is being pressed. The code of the control signal is compared with the predetermined code stored in the storage unit corresponding to the pressed button to determine whether the pressed button is malfunctional.

Method for detecting presses on buttons of an electronic device with a reduced number of General Purpose In/Out (GPI/O) ports includes a number of the GPI/O ports The number of the buttons is greater than the number of the GPI/O ports. A proportion of the buttons are each coupled between one of the I/O ports and ground, and the remaining proportion of the buttons are each coupled between any two of the I/O ports. The GPI/O ports are set to work in a first working state or in a second state to provide a first signal or second signal respectively. When a signal provided by a GPI/O port working at the first working mode changes, the method determines which one of the buttons has been pressed.

A data recovery system for recovering at least one system parameter of an electronic device. The electronic device comprises a first storage module for storing a check parameter and the system parameter, and a second storage module for storing a first default value corresponding to the check parameter and at least one second default value corresponding to the system parameter. The data recovery system comprises an obtaining module for obtaining a check parameter when the electronic device starts up, a determining module for determining whether the check parameter matches the first default value, and a recovery module for recovering the system parameter to a second default value when the check parameter is not the first default value. A storage medium with a recovery function and a data recovery method applied in the data recovery system are also disclosed.

An electronic device includes a power supply, a processor, a storage, and a detection circuit. The power supply provides driving voltage to the processor and the storage. The processor is capable of generating different instructions for processing the data stored in the storage. The detection circuit connected to the power supply and the processor detects whether the driving voltage is less than a reference voltage. When the driving voltage is less than the reference voltage, the detection circuit generates a control signal for controlling the processor to be disabled.
摘要:
An electronic device includes a power supply, a power consuming module, and a power control module. The power control module includes a capacitor, a detecting unit, and a control unit. A first end of the capacitor is connected to the power supply. Another end of the capacitor is grounded. The control unit includes a switching element. When the electronic device is powered on, the detecting unit controls the switching element to turn off, and the power supply supplies power to the power consuming module to charge the capacitor. When the electronic device is powered off, the capacitor discharges to supply power to the power consuming module. The detecting unit detects whether data storage of the electronic device is completed. When the data storage is completed, the detecting unit controls the switching element to turn on, causing the capacitor to discharge to ground. A power control module is also provided.
摘要:
An electronic device includes a first voltage module, a second voltage module, a key circuit, and a processor. The key circuit controls the first voltage module to provide different voltages to the processor based on different operations of user. The processor determines whether the voltage provided by the first module is changed by one pressed key from the key circuit. When the voltage provided by the first module is changed by two pressed keys from the key circuit, the processor does not compares the voltage provided by the first module to standard voltages and does not execute any function.
