Release 3.0 - Sep 2017

QTouch® Configurator Updates

  • QTouch Configurator has been updated for the SAMD20/SAMD21/SAMDA1/SAME51/SAME53/SAME54/SAMD51 set of devices.

QTouch Library Updates
  • Added device support for the SAMD20/SAMD21/SAMDA1/SAME51/SAME53/SAME54/SAMD51 set of devices.
  • Changed node group data structure for the SAMD10/SAMD11 device family.
  • Added example projects for the SAMD20/SAMD21/SAMDA1/SAME54 Xplained Pro kits using the QT1 extension board.
Known Issues & Limitations
  • ATSAMD21G17AU, ATSAMD21E16B and ATSAMD21E15C devices are not supported in IAR QTouch Example Projects.
  • Maximum number of configurable sensors supported by QTouch Configurator is limited to 100 sensors. This is applicable to the SAMD20/D21/E54/D51 device families having more than 32KB flash memory

    This restriction is from QTouch Configurator GUI not from the firmware side.

Release 2.0 Build 2 - June 2017

QTouch® Configurator Updates

  • Updated feature to gray-out of allocated PTC lines in the PIN selection drop down menu.
  • Updated QTouch Configurator guide on the Atmel start user guide.
  • Updated Atmel board example projects user guide.

QTouch Library Updates
  • Optimization settings of ATSAMD10 and ATSAMD11 IAR library modules are size-optimized.
  • Fixed bug related to on-board QTouch buttons channel order swap in the Tiny817-XPRO kit example project.
  • Fixed bug on SAM D10/D11 Datastreamer module code when acquisition auto tune is enabled. The CSD macro comparison is removed which is not applicable for this device.

Release 2.0 Build 1- May 2017

Device Support
The following table represents a list of devices supported by the QTouch Configurator and the maximum number of self-capacitance and mutual capacitance buttons supported for each device.

device-support-2p0.png

Note: The maximum number of self-capacitance buttons and mutual capacitance buttons is derived based on QTouch Modular Library RAM requirements.
Note: The PTC lines can be multiplexed to be used as either X or Y lines. This is considered when deriving the maximum number of mutual capacitance buttons.

New Features

  • Slider and Wheel.
  • Driven shield without dedicated pin support.
  • Frequency Hop without Auto tune support.

Known Issues & Limitations
  • For ATtiny81x devices, QTouch Configurator project export of only IAR Embedded Workbench is supported.
  • For ATtiny81x devices, when using Slider/Wheel sensors using QTouch Configurator, both Frequency Hop and Data Visualizer features cannot be enabled together in a project - this will result in code memory overflow. Either one of the features should be disabled for the touch example project to fit within device code memory.
  • For ATtiny161x devices, PB4 (Y13/X13) CAN be used as PTC X or Y line pin. However, this is NOT visible through the QTouch Configurator.
  • Following devices are NOT supported in start.atmel.com.
    1. ATtiny1614-SSNR, ATtiny1614-SSFR – SOIC
    2. ATtiny1616-MNR, ATtiny1616-MFR – QFN (ATtiny1616 SOIC package is supported)

    Contact Design Support if a QTouch® project is required for these devices.
