Product overview

Description

STMT/8L-EV1 is the STM8L evaluation board with a touch-sensing library which enables designers, who are familiar with the standard STM8Lxxx microcontrollers, to create higher-end look-and-feel user interfaces by replacing conventional electromechanical switches with touch-sensing controls. Designers can thus combine touch-sensing functions with traditional MCU features such as communication, LED control, beeper, LCD control, and so on.

The touch-sensing library is a complete, free source-code solution to transform any 8-bit STM8L microcontroller into a capacitive touchkey controller.

  • All features

    • Hardware solution designed with an STM8L151 device in a 48-pin LQFP package
    • Touch-sensing interface offering 10 touchkeys, 1 wheel and 1 slider
    • LCD display to report touchkeys, wheel and slider status and parameters
    • Configurable operation: debounce, low-power mode duration, recalibration time-out, wheel/slider resolution.
    • Embedded ST-Link interface for user firmware evaluation
    • Touch-sensing library featuring:
      • Robust and proven charge-transfer acquisition principle
      • Excellent immunity against conductive noise
      • Supports up to 16 capacitive sensing channels
      • Low BOM with only 1 I/O per channel + 1 I/O per acquisition group for sampling capacitors
      • Up to 8-bit resolution wheel/slider using 3 channels
      • Fast acquisition time (typically 2 ms for touchkey, 7 ms for wheel/slider)
      • Advanced processing featuring: Autocalibration, Debounce filtering, Environment control system (ECS), Detection exclusion system
      • Free C source code library
