TESTING SYSTEM AND METHOD OF INTER-INTEGRATED CIRCUIT BUS

摘要

A testing system configured to test real-time signals of an I2C bus of a motherboard includes an oscillograph and a testing device. The motherboard comprises an I2C master control device and an I2C slave device connected to the I2C master control device by the I2C bus. The oscillograph is connected to the I2C bus and configured to collect the real-time signals of the I2C bus. The testing device is connected to the motherboard and the oscillograph. The testing device is configured to send a testing command to start the I2C master control device and determine whether the real-time signals comply with predetermined parameters. The testing device is further configured to generate a testing report depicting whether the real-time signals comply with the predetermined parameters.
