Hardware debugging method for loopback interface

Abstract

The invention relates to the technical field of hardware debugging, in particular to a hardware debugging method for a loop interface, which comprises the following steps of: S1, measuring signal parameters of all pins of an analog-digital converter so as to check welding conditions and power supply conditions of all the pins of the analog-digital converter; S2, disconnecting an input resistor ofthe analog-to-digital converter, connecting an input end with an audio signal generator, and detecting the electrical performance of the analog-to-digital converter by adjusting the output level of the audio signal generator; S3, adjusting the maximum output level of the loudspeaker by adjusting the volume of the loudspeaker; s4, providing a signal feedback circuit, and adjusting the maximum inputlevel of the analog-to-digital converter through a reference signal provided by the reference signal feedback circuit; and S5, disconnecting the horn and the power amplifier from the signal to the audio signal generator, and detecting the electrical performance of the loop interface by adjusting the audio signal generator. The method has the beneficial effects of simplicity in operation, avoidance of repeated debugging, time and cost saving and avoidance of resource waste.

Description

technical field [0001] The invention relates to the technical field of hardware debugging, in particular to a hardware debugging method of a loopback interface. Background technique [0002] With the popularization and application of smart electronic products, smart TVs, smart set-top boxes, smart speakers, etc. are electronic products that require voice control, and their voice control needs to be processed by a microphone. The voice recognition function of the microphone is very important for voice-controlled electronic products. . [0003] In the prior art, the relevant electrical performance indicators of the loopback interface channel cannot meet the requirements, often resulting in unrecognizable voice or poor voice recognition; and according to actual use, it is found that the voice cannot be recognized or the voice recognition is poor, and then the reason is found. The above methods need to be wasted A lot of time, manpower and money cannot completely solve a series...
