DEMOMPR083

MPR083 Touch Sensor Demonstration Board

The is an demo board for MPR083. The MPR083 is an Inter Integrated Circuit Communication I2C driven Capacitive Touch Sensor Controller, optimized to manage an 8-position rotary shaped capacitive array. The device can accommodate a wide range of implementations through 3 output mechanisms, and many configurable options.

Rejects unwanted multi key detections from EMI events such as PA bursts or user handling

.

Ongoing pad analysis and detection is not reset by EMI events

.

Data is buffered in a FIFO for shortest access time

.

IRQ output advises when FIFO has data

.

Current rotary position is always available on demand for polling based systems
