I am trying to achieve a sensing distance of around 4~5 cms using PCF8883 on OM11055 eval board. I am attaching an external sensing plate of area around 4"x4". I followed steps form UM10370 like cutting the CP1 connection etc...
But what I am observing is whole PCB is turning sensing to touch.
What should be optimal component values(CCPC,CCLIN ,RC etc.) for this sensing distance . I am on a tough timeline for this project .So Request your urgent help.
