[mythtv-users] Mac Mini Remote Went Crazy

[Doug Haber]

Thanks Jean,

I set up my Harmony 520 as you describe below but I still get the
interference signals regardless of how many times I change the apple mini
remote settings (I tried ~10 times).  Do you always get the interference? Is
there any way to tell lirc to treat the interference as a different remote
(and thus not mess with Myth)?

Thanks again,
Doug

I've also noticed that changing the volume on my amplifier (which uses
Philipps IR code) would sometime confuse the mac mini which would also
act as if I had sent a signal using the Apple remote.

Same thing when using my Sony remote ; if I keep a button pressed to
change the volume ; the mini picks it up from time to time.

probably not, but you can help the situation.

You can change the codes sent by the Apple remote by pressing Play and
Menu for 10s
I have done so a few times to record with my Harmony remote 28
different IR signals, so I can do everything I need (record, menu
etc...)

My lircd.conf looks like this:

begin remote
  name  Apple_A1156
  bits            16
  eps            30
  aeps          100

  one             0     0
  zero            0     0
  pre_data_bits   16
  pre_data       0x87EE
  gap          211984
  min_repeat      119

      begin codes
          PLUS                     0xA00B
          MINUS                    0xA00D
          PLAY                     0xA004
          FORWARD                  0xA007
          REWIND                   0xA008
          MENU                     0xA002
          PLUS2                    0x8E0B
          MINUS2                   0x8E0D
          PLAY2                    0x8E04
          FORWARD2                 0x8E07
          REWIND2                  0x8E08
          MENU2                    0x8E02
          PLUS3                    0x900B
          MINUS3                   0x900D
          PLAY3                    0x9004
          FORWARD3                 0x9007
          REWIND3                  0x9008
          MENU3                    0x9002
          PLUS4                    0x930B
          MINUS4                   0x930D
          PLAY4                    0x9304
          FORWARD4                 0x9307
          REWIND4                  0x9308
          MENU4                    0x9302
          PLUS5                    0x960B
          MINUS5                   0x960D
          PLAY5                    0x9604
          FORWARD5                 0x9607
          REWIND5                  0x9608
          MENU5                    0x9602
      end codes

end remote

The Apple remote send code like 0x87EExxyy
As you can see, each time you press Menu and Play together it will
increment xx by 1.
Then it always uses the same hex code for the buttons.

I have noticed sometimes that the code for PLUS would change from xx0B
to xx0A ; not sure precisely when this happens, however when it does
the mac mini has more trouble recognising the IR signal and it's less
reliable.
