Pin Selection Mutual Capacitance

In case mutual capacitance is selected as technology, the channels of sensors need to be assigned to nodes. Nodes are formed by the intersection of X Lines and Y Lines of PTC devices.

The figure below shows auto assignment where technology is mutual capacitance.



The pin selection pane displays the block diagram of device with both X and Y pins.

The sensors have 4 channels each and these are assigned automatically to nodes formed by Y Line Y0 and X Lines X0 to X7.

The channel assignment pane in the right side shows the assignment information for each of the channel of the sensors.

If the assignment has to be edited to include a different set of nodes, the XY Line selection pane can be used as shown below.

Click on X Y Line Selection pane and add additional X and Y lines.



Note that additional X Line X8 and Y Line Y1 are now included. As a result there are additional nodes available.

The channel assignment can now be modified. This is shown below.



The assignment information is now changed to make use of additional nodes.
