Embodiment 1
[0029] In order to improve the efficiency of key detection, the key detection method provided by the embodiment of the present invention can arrange the keys to be detected whose total number of keys is S on the M*N keyboard array, and perform the key detection on the M*N keyboard array. Grouping, for example, the buttons to be detected in the same row are grouped into one group, or the buttons to be detected in the same column are grouped into one group, whether grouping by row or by column is determined by the value of M and N; grouping all buttons in the same group Simultaneously press to detect.
[0030] Next, the implementation of the button detection method will be introduced in detail.
[0031] Such as figure 1 As shown, the embodiment of the present invention provides a key detection method, the method includes:
[0032] 101. Determine the minimum value L of the number of I / O lines for detecting the key to be detected according to the total number S of keys to be det...

The invention provides a press key detection method, which relates to the technical field of electronics. After the press key detection method is applied, the press key detection time can be shortened, and the press key detection efficiency is improved. The method comprises the following steps of according to the total amount S of press keys to be detected, determining the minimum value L of the number of the I / O lines of the press keys to be detected; according to the total amount S of the press keys to be detected and the minimum value L of the number of the I / O lines, determining a detected press key array which is an M*N keyboard array; if M and N are unequal, determining the smaller value of M and N as a grouping number; if the grouping number is M, dividing N press keys to be detected in each line into one group; if the grouping number is N, dividing M press keys in each row into one group; connecting L I / O lines with the lines and the row lines of M*N keyboard arrays; carrying out press key detection by taking the group as the unit. The embodiment of the invention is mainly applied to the press key detection process.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a key detection method. Background technique [0002] When performing button detection on terminals such as smart key devices and OTPs with button functions, the following methods are usually used to detect each button individually. The following uses the detection process of a button on the keyboard array as an example to illustrate: [0003] Connect the I / O line to the row line and column line where the key is located, and set the level of the row line where the key is located to high level and the level of column line to low level through the I / O line. The key is located at the intersection of the row line and the column line, and when the key is not pressed, the row line and the column line at the intersection are in a disconnected state. When the button is pressed, if the button is normal, the row line and the column line will be turned on. At this time, the row line le...
