Abstract

The invention discloses a test system for an audio interface of a wireless communication module. The wireless communication module comprises pins MICP, MICN, SPKP and SPKN, a first GPIO and an analog-to-digital conversion interface. The test system comprises a first conversion circuit, a second conversion circuit and a first switching circuit; audio signals input by the MICP and the MICN are output to the SPKP and the SPKN; the first conversion circuit converts the received SPKP signal into a first signal and outputs the first signal to the first input end of the first switching circuit; the second signal conversion circuit converts the received SPKN signal into a second signal and outputs the second signal to the second input end of the first switch circuit, the first switch circuit outputs the first signal or the second signal to the analog-to-digital conversion interface under the control of the first GPIO, and whether the test is passed is judged according to the voltage data of the analog-to-digital conversion interface. According to the audio interface testing system of the wireless communication module, testing equipment is simplified, and testing is convenient.

Description

technical field [0001] The invention relates to the testing field, in particular to a testing system for an audio interface of a wireless communication module. Background technique [0002] Wireless communication modules and some mobile phone devices with wireless communication modules need to be tested for audio interfaces. There are physical pins MICP, MICN, SPKP and SPKN on the wireless communication module. In the prior art, when performing audio interface tests on wireless communication modules and some mobile phone devices with wireless communication modules, the general practice is to connect the wireless communication module under test or mobile phone devices with wireless communication modules to external microphones and speakers, and the wireless communication module to be tested The pins MICP and MICN of the communication module are connected to an external microphone, input an audio test signal through the external microphone, connect the pins SPKP and SPKN of th...
