Abstract
Optical modules are the core components of optical communication systems.Optical modules with different speeds and packages need to exchange monitoring data with the host by means of I2C communication,and execute real-time control commands sent by the host.Therefore,a testing system for optical module I2C communication is introduced.The high-precision command control is realized by combing QSPI and PDMA functions of MCU,and all I2C timing indicators tests and logic tests at different speeds are achieved by means of the instruction splicing.The working principle,hardware and software design method of the system are introduced.I2C tests at different rates were conducted.The testing results show that this system has strong feasibility and can improve testing efficiency substantially.关键词
