The existing CapSense component in Creator does not support slider with mutual capacitance.
But you could use slider with mutual capacitance by following the steps below.
1. Create a CSX button widget with the number of buttons equal to the number of segments in the slider
2. Create a CSD slider widget with the required number of segments
3. Assign all the receiver pins of CSD slider widget to the receiver pins of CSX button widget. (In widget details tab)
4. Assign the transmitter pin of CSD slider widget to the transmitter pin of CSX button widget. (In widget details tab)
5. In firmware, scan all the buttons and copy paste the raw counts into slider (Use get_param and set_param APIs)
6. Process the slider widget
Thanks and regards,
