1. A system for use with a knitted textile having a plurality of pressure sensing points, the system comprising:
a plurality of column lines connected to the textile and a first multiplexer;
a plurality of row lines connected to the textile and a second multiplexer; and
one or more digital circuits configured to:
control the first multiplexer to periodically switch a voltage supply to each of the plurality of column lines while putting the rest of the column lines on high-impedance,
control the second multiplexer to sequentially connect to ones of the plurality of row lines to a potential divider while grounding the other row lines for reading out values of the plurality of pressure sensing points, and
provide the values of the plurality of pressure sensing points to a processing system configured to generate one or more pressure distributions based on the values of the plurality of pressure sensing points and to recognize activities of a wearer of the knitted textile based on the pressure distributions and using machine learning (ML).
