The user interface of a product is a key element that design engineers need to address to provide a compelling user experience. Touchpads, slides and rotaries offer a more intuitive and effective way of user interaction than traditional buttons. And, designing a touch-based user interface is simplified with the NXP Touch solution. This solution includes software that is designed to work simply and seamlessly with NXP’s capacitive touch sensing hardware IP that’s available on Kinetis KE15Z MCUs. Key benefits of the NXP Touch solution include:
For easy starting and designing, NXP does lots of work in SW enablement – NXP Touch Library, which is based on the MCUXpresso SDK:
Kinetis KE15Z: KE1xZ MCUs are based on the Arm® Cortex®-M0+ core, running up to 72 MHz. These MCUs support up to 256 KB flash, 32 KB RAM, and a complete set of analog/digital features. The robust TSI module provides a high level of stability and accuracy to any HMI system. The 1-Msps ADC and FlexTimer modules provide a perfect solution for BLDC motor-control systems.
FRDM-KE15Z: The FRDM-KE15Z Freedom Board is designed to work in standalone mode or as the main board of FRDM-TOUCH, FRDM-MC-LVBLDC, and Arduino boards. This Freedom board is compatible with DC 5v and 3.3v power supply and features a KL15Z, a device boasting up to 256KB Flash and 32KB SRAM and numerous analog and digital peripherals. The onboard interfaces include an RGB LED, a 6-axis digital sensor, a 3-axis digital angular rate gyroscope, an ambient light sensor, and a capacitive touch slider.
FRDM-TOUCH: The FRDM-TOUCH is a Touch Module for FRDM-KE15Z with Capacitive Touch sliders. This board can connect FRDM-KE15Z and control the onboard RBG LED by using keys, slider and rotary touches.
NXP Touch Library: NXP Touch software is designed to speed development of your touch applications and is ideal for use with Kinetis® MCUs. Available as a source code, this software download features touch detection algorithms and is ideally suited for RTOS based applications. NXP Touch software employs a modular architecture with a variety of touch-centric controls, modules, and electrode data objects, enabling integrated and customizable features.
