SAMA5D2-PTC-EK

Part Number: ATSAMA5D2-PTC-EK

Summary:

The SAMA5D2-PTC-EK is used to develop and evaluate capacitive touch controls using the Peripheral Touch Controller (PTC) module contained in the SAMA5D2 MPU family. The PTC provides built-in hardware for capacitive touch measurement on sensors that function as buttons, sliders, wheels or a touch pad.  The PTC supports both self and mutual-capacitance measurements, up to an 8x8 button matrix,

Summary

The SAMA5D2-PTC-EK is used to develop and evaluate capacitive touch controls using the Peripheral Touch Controller (PTC) module contained in the SAMA5D2 MPU family. The PTC provides built-in hardware for capacitive touch measurement on sensors that function as buttons, sliders, wheels or a touch pad.  The PTC supports both self and mutual-capacitance measurements, up to an 8x8 button matrix, without the need for any external components.  Features include adjustments for sensitivity and noise tolerance, as well as self-calibration, minimizing user tuning efforts. The PTC runs the QTouch Modular Library (QTML).  A GUI-based PTC Toolbox software program is used to configure the touch features.  QTouch extension boards QT1, QT2 and QT6 attach to the PTC-EK's XPRO wing connectors to demonstrate buttons, sliders, wheels and touch pad operation.
