I am working with AD7142 for proximity detection. But still I cannot achieve it correctly because of the wrong register configurations. Any one can provide a sample code for this? I am resolving the same issue for the last 5 months. Any one please help me.
For proximity detection, the AD7147 product is a better option as it measures self capacitance compared to mutual capacitance measured by the AD7142, self capacitance offers greater sensitivity for proximity detection. Having said this the AD7142 and AD7147 products are designed for user input button applications and may not have the sensitivity required for proximity detection, the sensor design will greatly impact the performance. Please refer to application notes on our website for device configuration and sensor design guidelines.
