JP1 Remotes

[jamus]

I'm using the iPod Remote V3 for my Apple TV:

Works great, but I would like to tweak it a little bit. If I understand correctly, the power button and fast forward/rewind buttons are setup to send the remote code longer. I believe that this would be done by the upgrade protocol.

I would like to do the following:

1) Increase the time of the remote signal for the power button
2) Decrease the time of the remote signal for fast forward/rewind.

Where should I be looking to do this? I have a 15-1994 remote

Not sure a newbie will be able to help a newbie, but maybe we can help others better understand you.
I'll assume that you meant to say you're using the ipod remote V3 upgrade.
Are you looking to decrease or increase time of the signals, or the button press? I'm only guessing, but I'd have to say that the Apple remote sends out the 'length' of signal required to get each desired function, change the 'length' of the signal and you probably won't get the desired effect.

As I understand it, these are the overloaded buttons...

Button --> Short --> Long
play --> play/pause/on --> OFF
skip+ --> skip+/on --> ffwd
skip- --> skip-/on --> rew
menu --> n/a --> n/a

I have tweeked the protocol a bit (see code below)
To make a button repeat-short you add 128 to it's OBC.
To make a button repeat-long you add 192 to it's OBC.

I've set the repeat-short to 15 repeats (hex 0F) and the repeat-long to 22 repeats (hex 16). You can adjust these times yourself by editing the protocol code below before using it.

Upgrade protocol 0 = 01 FF (S3C8) Apple iPod Remote v3.1
44 8D 31 8B 12 C7 4D 08 08 01 13 03 43 01 13 01
0E D2 F0 11 A5 08 B6 E6 0D 01 18 06 37 10 09 E6
0D 0F 37 12 03 E6 0D 16 E4 05 06 56 C1 FC 19 05
8D 01 33
End

If you don't need the repeat-short functionality, you could adjust the values in the original protocol without adding the extra code.

The non-repeat is set to 1 (hex 01) and the repeat is set to 18 (hex 12) in the original code.

Upgrade protocol 0 = 01 FF (S3C8) Apple iPod Remote
44 8D 31 8B 12 C7 4D 08 08 01 13 03 43 01 13 01
0E D2 F0 11 A5 08 B6 E6 0D 01 18 06 37 10 03 E6
0D 12 E4 05 06 77 10 19 05 8D 01 33
End

I would take initiative and try to create a new remote file for the files section, but since the original upgrade had protocol upgrades for multiple devices, it's way out of my leauge. Instead, I'll share my experiences:

First, to create the "perfect" remote upgrade, I did need the short and long repeats. That was key, and I appreciate the help.

I'll list each button, and the "overloads" of each:

button: play/pause
normal press: play/pause
long repeat: "sleep"

button: skip+/skip-
normal press: next song (music), next chapter (movie)
short repeat: fast forward 5 seconds and continue playing (music), start or increase fast forward (movie)
held down: continue fast fowarding (music), increase fast foward speed (movie)

button: menu
normal press: menu

I used this protocol upgrade (05 repeat for short press, and 16 for long press):

Upgrade protocol 0 = 01 FF (S3C8) Apple iPod Remote v3.1
44 8D 31 8B 12 C7 4D 08 08 01 13 03 43 01 13 01
0E D2 F0 11 A5 08 B6 E6 0D 01 18 06 37 10 09 E6
0D 05 37 12 03 E6 0D 16 E4 05 06 56 C1 FC 19 05
8D 01 33
End

Then I changed the OBC of the power button to 197. Finally, I updated the up/left/right/down arrows to match the position of the keys on the remote. I guess whoever created the original iPod remote wanted a different layout, but it made it impossible to navigate the Apple TV.

I'm glad it worked for you.
