Sampling Rate and Subsampling
Throughout this document, sampling rate refers to the rate at which the sequencer produces samples
of the same ADC channel. This depends on the number of enabled ADC channels and on
configuration of the subsampling feature of the sequencer.
Subsampling is used when the application requires lower sample rates than what is possible with the
configured SEQ_PER and SEQ_DIV values, and with the number of enabled ADC channels. Lower
sample rate can also be achieved by setting SEQ_PER and SEQ_DIV to large enough values, but this
is not advisable as SEQ_DIV is multiplied to all the timings of the sequencer, thus the LED pulses will
become very long, which is probably not desired. SEQ_DIV should be kept relatively small for finer
resolution of the times.
