FDC2214PROXSEN-EVM

The FDC2214PROXSEN-EVM is a proximity and capacitive touch sensing evaluation module. The FDC2214PROXSEN-EVM demonstrates capacitive proximity and capacitive touch button sensing with the use of TI's FDC221x capacitive sensing technology. The EVM is a complete hardware and firmware solution that integrates the 4-channel FDC2214, MSP430FR5969 and the TPS61029 into one design. The firmware processes the data with an adaptive algorithm to determine whether an object is in the intended sensing area. All of the processing is done on the MSP430 so the EVM is a standalone system. Dedicated coloured LEDs light up once the device detects a target in close proximity to the board or detects a touch on the buttons. The EVM is powered by one AA battery.

• Demonstrates proximity and cap touch capabilities
• Adaptive processing algorithm integrated in the firmware
• JTAG connection available for debugging
• Cap touch buttons and firmware optimized to be very responsive to quick user touch interactions
• Max sensing distance is 10cm (4inch) as a floating system and 50cm (19.6inch) as a grounded system
