8.17 ?filttype
8.17.1 Description
This command queries the type of filter being used; it acts independently on the accelerometer
and gyro filters, so each must be specified as a separate query. This returns custom type if the
=FC20 command was used to define the coefficients. In the 1775 IMU, if a semi-custom filter
configuration is being used this does not report the special configuration.
8.17.2 Usage
?FILTTYPE,<A|G>
8.17.3 Response
FILTTYPE,<A|G>,<CHEBY|BUTTER|AVE|custom>
