Such as: single / double / three hammer, short / long, There are various combinations of keystroke styles. The following procedures can be used. If the button is closed time 500MS, a judge for the short (0); If the button is closed for a long time 500MS, judge (1); The two keystroke interval should be 700MS. If no key is pressed after the release of the key, the read key is finished at 700MS. When the read key is completed, a key number is returned. The value is KEY_NUM. Its significance is as follows: KEY_NUM meaningno keys pressedmeaninglesssingle shortsingle long shotshort + shortshort and long. Click the +long shortlong hit + long shot ............ 100000007 short 111111117 long. The rule of the KEY_NUM value in the previous table is that, from left to right, each person following the first 1 represents a keystroke; 0 Stop, 1 represents a long strike. After mastering this rule, we can translate any binary number of 8 bits into one Keystroke combination. For example:stands for: short + long + short + long + short + long. The program can identify up to 7 consecutive keystrokes, a total of 254 combinations. But not every program is available. In most ways In order to determine double click, you can then define the ZHBIT in the program as 2. Similarly, if you want to judge the 3 press Key, define ZHBIT as 3. When the ZHBIT= is 1, the program can only determine a keystroke, including 2 combinations (short / long strike); when ZHBIT= is 2,. The order can judge two keystrokes, including 6 (2+4) combination (short / lo
