1. we are developing an application which need be deployed plenty of FDC2214 devices ,this application called 'birck lamp',we need to detect people walking on the bricks.
2. The application has the same schematic design according TI's FDC2214 EVM board on detecting/sensoring section, and has the same REG configuration.
3. Now we face a problem , we can get the raw data output from 2214's I2C port , before change it to Capacitor value data .
we just create a waveform line to observe the feature of output raw data, and we found that the waveform does not forward as a horizontal line, but in the trend of gradually decreasing in the first 30 minutes,
after about half an hour , the output just become a horizontal curve.
As a contrast , the raw code output waveform from TI's software (EVM board) is horizonal line from the beginning.
