Freescale releases latest Xtrinsic Touch-Sensing Software

Capacitive touch-sensing software 2.5 expands functionality for ColdFire+ and Kinetis microcontrollers

AUSTIN, Texas – April 26, 2011 – Today, Freescale Semiconductor released its latest microcontroller (MCU) based touch sensing software (TSS) for its popular touch sensing library and tool set. The TSS 2.5 expands capacitive touch sensing capability beyond Freescale's 8-bit S08 and 32-bit V1 ColdFire MCUs to the ColdFire+ and Kinetis MCU portfolios. Customers require innovative touch sensing development to deliver solutions with better performance and higher reliability. Full compatibility with Freescale’s broad MCU portfolio is designed to decrease time to market.

Customers need flexible devices and software that allow quick changes to interface designs with minimal effort, while still achieving a solid technical solution. The advanced touch sensing software 2.5 is complementary licensed software that simplifies touch key configuration by allowing many different electrode array combinations.

This version also supports the Touch Sensing Input (TSI) module in the ColdFire+ and Kinetis MCU families for highly accurate and robust hardware assisted touch sensing, providing designers low power modes (as low as 1 uA) with wake-up through touch via the TSI pins. The TSI module has extremely high sensitivity with a low capacitance measurement resolution. There is low central processing unit overhead since the TSI module can scan and accumulate measurement results without CPU intervention, since it has interrupts for end-of-scan and errors.

Touch Sensing Software features

  • CodeWarrior 10.1 and IAR support
  • Embedded Component for Processor Expert for easy graphical user interface
  • FreeMASTER graphical interface for configuration and tuning
  • Low power scanning support
  • Compatible with MQX RTOS (3.6 and up)
  • TSI module support for ColdFire+ and Kinetis MCUs
  • Improved touch detection algorithm for reduced false touches under electrical noise
