Abstract: In an embodiment, a method includes performing a calibration of a first touch cell of a touch screen, where performing the calibration includes: receiving a first code associated with the first touch cell; receiving a second code associated with the first touch cell; determining whether there is an indication of a touch of the touch screen based on the first and second codes; generating a raw code based on the first or second codes; receiving a third code associated with the first touch cell; determining whether the third code matches the raw code; and in response to determining that there is no indication of a touch of the touch screen based on the first and second codes, and that the third code matches the raw code, updating a calibration code associated with the first touch cell based on the raw code or the third code.
