DS90UB925QSQ//DS90UB926QSQX/NOPB问题请教



926 925 拓扑如下,主要想实现cpu-i2c-926-925-i2c-slavex,去配置slave。然后再讲业务数据读回来;

目前发现通过cpu无法查询到slave,可能是配置上的问题,目前926配置如下;

寄存器整体读回来如下(发现0x1C=02,不清楚什么原因)

请帮忙确认下926的配置是否有问题;

 

  • 你好,
    配置Ser与Deser的I2C连接,请遵循下述步骤:
    1设置I2C 透传
    2设置 alias of the paired ser,remote slave I2C addr. ID 和 alias ID
    3读/写remote slave with alias ID
    如下是一个供你参考的app. note, 所有的FPD-Link有相同的I2C运行流程
