Touch interfaces are often a more intuitive and effective form of user interaction than traditional buttons and can improve the overall user experience of a product. NXP provides software libraries and tools to complement our IEC 61000-4-6 certified and low-cost, capacitive touch solutions for the KE series and LPC804 MCUs, empowering you to move rapidly and smoothly from initial prototyping to full product development.

NXP Touch Library for KE1xZ MCUs
The NXP Touch Library is designed to work seamlessly with NXP’s touch sensing interface (TSI) peripheral available on the KE15Z MCU to detect finger touch, movement or gestures. Available as source code in the MCUXpresso SDK, this software includes touch detection algorithms and is supported by NXP FreeMASTER for visualization and debugging. Features of the NXP Touch Library include:
- Abstracted decoder controls, such as rotary, slider, keypad, analog rotary and analog slider
- Proximity and shielding electrodes
- Advanced filtering and integrating detection (AFID), signal adaptive filtering algorithm (SAFA) or “uni-directional” version of SAFA key detectors
- Liquid tolerance
- Sensitivity auto-tuning function – automatic TSI registers configuration

Capacitive Touch Sensing for LPC804 MCUs
The LPC804 family of general purpose MCUs features a capacitive touch interface (Cap Touch) that supports up to five mutual-capacitance touch sensors. Driver level examples are provided through the MCUXpresso SDK and the LPC804 Code Bundle packages as a starting point for user application development. Additionally, FreeMASTER support is available for monitoring the run-time sensor value.
