摘要： A data transmission method and a mobile terminal include taking bytes of data in universal asynchronous receiver/transmitter (UART) format generated by a mobile terminal, simulating UART ports via GPIO ports of a processor of the mobile terminal, and transmitting the bytes of data in UART format divided in batches to a receiving terminal via the GPIO ports. In transmitting the bytes of data in UART format in divided batches to the receiving terminal via the GPIO ports, the processor of the mobile terminal is in a locked state. The processor is in an unlocked state between two adjacent batches of the data transmitting.

摘要： Embodiments of the present disclosure provide a charging method, a charging device and a terminal. The charging method includes: when detecting that a battery is charged with a trickle current, acquiring a voltage of the battery; determining a preset voltage range to which the voltage belongs; acquiring a charging current corresponding to the preset voltage range; and charging the battery according to the charging current. During a process that the battery is charged with the trickle current, the battery may be charged with a different charging current when the voltage of the battery belongs to a different voltage range, thereby improving the flexibility of a trickle current charge phase.

摘要： A method of upgrading firmware of an adapter includes transmitting a set of n data blocks of first upgrade file to the adapter, receiving a first response information of the adapter based on the set of n data blocks, and determining that the updating procedure of the adapter fails when the first response information indicates that the adapter fails to receive all of the n data blocks. In the method, a mobile terminal transmits the upgrade file to the adapter and the adapter sends determination information to the mobile terminal after the adapter receives the upgrade file having a predetermined size. In a time interval, if the mobile terminal fails to receive the determination information or the adapter does not receive the upgrade file, the upgrading firmware of the adapter fails.

摘要： An electronic device and a power adapter are provided. The power adapter comprises a power circuit, a main control circuit, a potential adjustment circuit, a current detection circuit, a voltage detection circuit and an output switch circuit. When a conventional charging or a quick charging is performed on the battery in the electronic device, the main control circuit determines whether the output current of the power adapter is greater than a current threshold according to the current detecting signal and determines whether the output voltage of the power adapter is greater than a voltage threshold according to the voltage detecting signal; if the output current of the power adapter is greater than the current threshold and/or the output voltage of the power adapter is greater than the voltage threshold, the main control circuit controls the output switch circuit to turn off the direct current output of the power adapter.

摘要： The present disclosure relates to the technical field of charging. A terminal and a battery charging control device and method are provided. The battery charging control device including a battery connector, a main control circuit and a quick charging switch circuit is adopted. During the regular charging or the quick charging, the main control circuit performs a data communication with the external power adapter via the communication interface, and obtains a charging voltage and a charging current for the battery; if the charging voltage is greater than a voltage threshold and/or the charging current is greater than a current threshold, the main control circuit sends a charging switch-off instruction, such that the controller controls the communication interface to switch off; if the charging voltage is less than or equal to the voltage threshold and the charging current is less than or equal to the current threshold, the main control circuit continues to obtain the charging voltage and the charging current.

摘要： The present disclosure provides a method and an apparatus for charging and a terminal. In the present disclosure, remaining electric quantities in the two batteries may be acquired. A trickle-current charging and a constant-current charging may be performed on a first battery of the two batteries in sequence when the remaining electric quantities in the two batteries are less than a preset value. It may be stopped to charge the first battery and the trickle-current charging and the constant-current charging may be performed on a second battery of the two batteries in sequence when a charging state of the first battery is changed from the constant-current charging to a constant-voltage charging. The constant-voltage charging may be performed on the two batteries simultaneously when the constant-current charging for the second battery finishes.
