After I set my filter coefficients, I was able to use the Linux API to "cat filter_fir_config" and that gives me "FIR Rx: 128, 4 Tx: 128, 4" How do I do that using the iio library functions?
I am able to set the coefficients using iio_device_attr_write_raw(). I tried to read back using iio_device_attr_read(), but I am only able to get weird symbols.
Does any one know how I can do this? Will like to verify in code that my FIR filter coefficients are loaded correctly. Thanks!
