Abstract
A method and a system for enabling a touch controller to be adaptive to a capacitive touch sensor are disclosed. The method may include: step A in which the touch controller detects and samples all the capacitors in the sensor model identification circuit and parses the sampled data; and step B in which the touch sensor selects parameters corresponding to a sensor model in accordance with a parsing result of step A to perform touch detection processing to the capacitive touch sensor. The disclosed methods and systems which are easy to implement and have lower cost can be applied in various digital products with capacitive touch screens, which not only facilitates replacing touch panel modules with different models or supplied by different suppliers, but also can ensure ideal touch detection results.
