Abstract:
1. A method for enabling a touch controller to be adaptive to a capacitive touch sensor, the capacitive touch sensor connected to a capacitor-based sensor model identification circuit, the method comprising: 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, wherein step A comprises: step A1 in which the touch controller identifies a largest value from relative capacitance data obtained by sampling and format-converts the largest value according to a preset number of grades; step A2 in which remaining relative capacitance data other than the largest value are format-converted according to the preset number of the grades and a difference between the remaining relative capacitance data and the largest value; and step A3 in which a model of the current capacitive touch sensor is obtained according to code values resulted from format-converting all the relative capacitance data and correspondence between preset code values and sensor models.
