Data Filtering
Description
Fix Status
Addition of two on-chip filtering algorithms for improved Averaging Filter
CapSense performance and better noise immunity. This smoothens the raw count data, and
results in better noise immunity and
performance. The filter can average 2, 4, 8,
or 16 samples.
Drop the Sample Filter
This discards any acquired CapSense
sample if an I2C communication occurs after
the scan process has already started.
For more information on filtering, refer to
application note AN48430 “CapSense
Express-Noise Filtering Methods”.
