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
What would be helpful is a list of required device tree properties for the ADIS16448 like you have for the 16480. Or are they the same?
For those drivers, the ADIS16448 is most like the ADIS16400.
By the way, you might want to post this question, in this forum.
i cant find anything listing required device tree properties for the ADIS16400
Here is the link that shows up with the ADIS16448 (ADIS16400):
If this does not have what you need, can you please submit a request for what you need, in this forum?
