PSoC® 4 CapSense®: Linear Slider-Specific Issues
Linear Slider-specific issues
A. Check if the CapSense slider design rule is followed correctly. The parasitic capacitance of the slider should be uniform for good linearity.
B. When the slider is not touched, the centroid position returned will be 0xFF. When there are multiple touches on the slider, the lowest position will be reported.
C. When duplexing is enabled, the sensor assignment should be as per the recommendation. For details of the sensor assignment, refer to page no.98 of the CapSense datasheet.
