An electronic device and control method

Abstract

The invention discloses an electronic device and a control method. The electronic device comprises: a processor; at least one data interface including a first data interface connected with the processor, the electronic device can be connected with the second electronic device through the first data interface, The first data interface includes: a first voltage dividing element; a first pin, which can be grounded or directly grounded through the first voltage dividing element; a second pin, when the electronic device is connected to the second electronic device through the first data interface, and When the first pin is directly grounded, the second pin is connected to the first power supply of the second electronic device; wherein, when the electronic device is connected to the second electronic device through the first data interface, and when the first pin is connected to the second electronic device through the first data interface When the voltage dividing element is grounded, the second pin is disconnected from the first power supply, and the processor controls the second pin to be connected to the second power supply connected to the electronic device, so as to supply power to the second electronic device, and the first electronic device can pass the first electronic device. The device powers the second electronic device.
