ADIS16448 registering Interrupt with driver

Do you have any documentation on how to register a GPIO pin as a interrupt

    Thank you for posting your question in this forum and for your interest in the ADIS16448.  To be honest, I am not 100% sure that I understand what you are trying to accomplish.  Do you want the device to generate an interrupt signal or have some sort of functional response to an external interrupt signal?  Either way, what function will be tied to this interrupt?  Thank you!

  • I guess i should backup to the original problem .  We are seeing inconsistent data rates when using  ioctl(fd, SPI_IOC_MESSAGE(1), &spi) or iio_channel_attr_read(chn, "raw", buf, sizeof(buf));.  Ideally we would like to read the data in at 800Hz but 500Hz would be sufficient  .   

    HW configuration:   IMU is connected to the NVIDIA TX1 ,  DIO1 is not connected
