Method of acquiring data from a matrix touch sensor by performing global measurement and conditional sequential measurement
Abstract:
A method of acquiring data of a matrix touch sensor including a matrix array of cells arranged according to a set of rows and columns, the method including: activating the cells arranged according to a column of at least one subset of columns of the matrix touch sensor; taking an overall measurement of an overall electrical characteristic on all the rows of at least one subset of rows of the matrix touch sensor; taking a sequential measurement of an electrical characteristic successively on each row of the at least one subset of rows, if the overall electrical characteristic has a value representative of a contact on at least one of the cells arranged according to the column; and repeating the overall measurement and sequential measurement after activating the cells arranged according to another column of the at least one subset of columns of the matrix touch sensor.
Abstract(Chinese):

一种获取矩阵式触摸传感器的数据的方法，该矩阵式触摸传感器包括根据一组行和列设置的矩阵阵列，该方法包括：激活根据矩阵式触摸传感器的列的至少一个子集的列排列的单元 ; 对矩阵式触摸传感器的行的至少一个子集的所有行的总体电特性进行总体测量; 如果整个电特性具有表示根据列排列的至少一个单元上的接触的值，则连续地对所述至少一行的每一行进行电特性的连续测量; 以及在激活根据矩阵式触摸传感器的列的至少一个子集的另一列布置的单元之后重复总体测量和顺序测量。
