3.1.4.4 Frequency Hop AutoTune API
touch_ret_t qtm_freq_hop_autotune(qtm_freq_hop_autotune_control_t *qtm_freq_hop_autotune_control);
Description: Performs the Frequency Hopping Autotune algorithm, measures noise in the
signal value and, based on the noise level, changes the frequency set used for
acquisition. This routine also chooses the next measurements frequency from the
frequency-set and perform median filter on the signal value. It must be called after
calling qtm_acquisition_process().
