22 单键：以K1为例，K1按键产生的流程如下所示：
|

23
|
||||
24 --> K1|KEY_BREAK(短按松开)
|

25 -
|

26 K1(按下)--
|

27 -
|

28 --> K1|KEY_LONG_START(长按大约1秒)---> K1|KEY_LONG(一直长按，约每300ms产生长按键)---->K1|KEY_LONG_BR
|

-EAK(长按松开)

|
||||
32
|
||||
33 复合键：
|
||||
34 以K1(K1=0x0001),K2(K2=0x0002)为例， 当K1，K2同时按下时，产生按键为(K1<<5)|K2，即0x22, 产生按键的流程如下所
|
||||
-示：
|
||||
35
|
||||
36
|
||||
37 --> ((K1<<5)|K2)|KEY_BREAK(短按松开)
|
||||
38 -
|
||||
39 (K1<<5)|K2(按下)--
|
||||
40 -
|
||||
41 --> ((K1<<5)|K2)|KEY_LONG_START(长按大约1秒)---> ((K1<<5)|K2)|KEY_LONG(一直长按，约每300ms产生长
|
||||
-按键)---->((K1<<5)|K2)|KEY_LONG_BREAK(长按松开)
|
||||
42 ^ |
|
||||
43 | |
|
||||
44 |---------------------------------------------------------|
|
||||
45 注意：由于复合键按下时，软件不一定同时检测到双键，而是先检测到单键按下，例如先检测到K1，此时会先产生K1键，
|
||||
-等到检测到K2也按
|
||||
46 下时，才会产生按键(K1<<5)|K2，检测到双键后，如果双键一直按下，会产生((K1<<5)|K2)|KEY_LONG_START和((K1<<5)|
|
||||
-K2)|KEY_LONG，如果
|
||||
C51 COMPILER V9.51 KEY 03/07/2018 10:41:04 PAGE 2
|
||||
|
||||
47 有一个键先松手，会停止产生按键， 等到双键都松开时，才会产生((K1<<5)|K2)|KEY_BREAK(短按松开)或((K1<<5)|K2)|
