Abstract

The invention provides a current testing method and electronic equipment. The current testing method comprises the following steps: sampling the voltage on a first resistor to obtain a first voltage through an ADC, wherein the first resistor is connected in series on a loop between the electronic equipment and a battery of the electronic equipment; obtaining a first current according to a ratio of the first voltage to first resistance. According to the current testing method and the electronic equipment provided by the invention, the voltage of the first resistor is sampled through the ADC of the electronic equipment, and the first current is obtained through the electronic equipment, so that other testing equipment does not need to be arranged when the current is tested, and the current testing method is simplified.

Description

technical field [0001] The invention relates to electronic technology, in particular to a current testing method and electronic equipment. Background technique [0002] Regardless of whether the electronic equipment is tested before leaving the factory or after it is put into use, it is necessary to obtain the current of the electronic equipment when it is running, so as to obtain the power consumption through the current and judge the working status of the electronic equipment. [0003] In the prior art, in order to obtain the operating current of the electronic equipment, an external DC power supply is used to supply power to the electronic equipment, and the current output from the DC power supply to the electronic equipment is detected by a computer, thereby obtaining the operating current of the electronic equipment. [0004] With the prior art, more instruments are needed to test the current of the electronic equipment, and the method for testing the current is relativ...
