Description
- TIDA-00474, Robust, High Res Capacitive Touch/Proximity Sensing User Interface (UI) w/LED Lighting Ref Design. Capacitive sensing based touch button implementation is commonly used, for the user interfaces in home appliances. Solutions based on low measurement resolution, suffer from achieving reliable operation and faster user response. The design TIDA-00474 hardware platform demonstrates the mitigation of these challenges using EMI-resistant, high-resolution (up to 28 bits), high-speed capacitance-to-digital converters. The board is designed and tested in cooker hood environment. Implementation details and test results are provided for capacitive button sensing and long range proximity sensing (up to 30cm)
