The world's most energy friendly microcontrollers2013-09-16 - Design for CapacitiveTouchAN0040 - Application NoteIntroductionThis application note covers the basics of Hardware Design for Capacitive touchsensing with the EFM32 microcontrollers. Both simple Touch buttons and moreadvanced sliders and Touch matrices are described, along with key pointers of howto achieve the best possible Capacitive Touch performance with the EFM32. Forthe lowest energy consumption and "wake on Touch " functionality , an EFM32 withLESENSE should be application note focuses on how to Design Hardware for Capacitive Touch withthe EFM32 microcontroller.
