    dears:
    

           now i am taking a project by using ADPD105.
    

           The problem I have now is to use FIFO mode to generate interrupt through FIFO level, but configure relevant registers according to the steps provided in the manual. The specific register configuration is as follows:
    


          0x11: 0x3131
    


          The adpd_water processing parameter is 3,
    


          The value read 0x06 is: 0x1700
    


          Gpio0 is used as an interrupt,
    


          0x01:0xC09F
    


          0x02: 0x0107 (polarity reversed, no effect)
    


          0x0b: 0x1001 (gpio1 output low level, gpio0 provides interrupt function)
    


          However, gpio0 does not interrupt the signal output when measured with an oscilloscope
    


          Can you tell me if there is a problem with the configuration? Or can the driver of interrupt mode be provided for reference?
    

    

    thanks!
