ユーザースイッチの入力を記録し、それを再生することで、ユーザースイッチの入力をコマンドから行います。
ユーザースイッチの入力を記録するには、evemu-recordコマンドを使用します。
※ここでは例として、out.logにユーザースイッチの入力を記録しています。
[armadillo ~]# evemu-record /dev/input/event0 out.log （ユーザースイッチを押下） （Ctrl+Cを入力） [armadillo ~]# cat out.log # EVEMU 1.3 # Kernel: 4.14-at38 # Input device name: "gpio-keys" # Input device ID: bus 0x19 vendor 0x01 product 0x01 version 0x100 # Supported events: # Event type 0 (EV_SYN) # Event code 0 (SYN_REPORT) # Event code 1 (SYN_CONFIG) # Event code 2 (SYN_MT_REPORT) # Event code 3 (SYN_DROPPED) # Event code 4 ((null)) # Event code 5 ((null)) # Event code 6 ((null)) # Event code 7 ((null)) # Event code 8 ((null)) # Event code 9 ((null)) # Event code 10 ((null)) # Event code 11 ((null)) # Event code 12 ((null)) # Event code 13 ((null)) # Event code 14 ((null)) # Event code 15 (SYN_MAX) # Event type 1 (EV_KEY) # Event code 28 (KEY_ENTER) # Properties: N: gpio-keys I: 0019 0001 0001 0100 P: 00 00 00 00 00 00 00 00 B: 00 0b 00 00 00 00 00 00 00 B: 01 00 00 00 10 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 02 00 00 00 00 00 00 00 00 B: 03 00 00 00 00 00 00 00 00 B: 04 00 00 00 00 00 00 00 00 B: 05 00 00 00 00 00 00 00 00 B: 11 00 00 00 00 00 00 00 00 B: 12 00 00 00 00 00 00 00 00 B: 14 00 00 00 00 00 00 00 00 B: 15 00 00 00 00 00 00 00 00 B: 15 00 00 00 00 00 00 00 00 ################################ # Waiting for events # ################################ E: 0.000001 0001 001c 0000 # EV_KEY / KEY_ENTER 0 E: 0.000001 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- +0ms E: 0.200008 0001 001c 0001 # EV_KEY / KEY_ENTER 1 E: 0.200008 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- +200ms E: 0.799998 0001 001c 0000 # EV_KEY / KEY_ENTER 0 E: 0.799998 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- +599ms E: 1.049998 0001 001c 0001 # EV_KEY / KEY_ENTER 1 E: 1.049998 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- +250ms E: 1.699994 0001 001c 0000 # EV_KEY / KEY_ENTER 0 E: 1.699994 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- +650ms E: 2.609999 0001 001c 0001 # EV_KEY / KEY_ENTER 1 E: 2.609999 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- +910ms
次に、記録したユーザースイッチの入力を再生するにはevemu-playコマンドを使用します。
また、確認用にevtestコマンドをバックグランドジョブで実行します。
