JP1 Remotes

[binky123]

This remote uses 2 bytes for the protocol id in the device upgrade. Can you post your device and protocol upgrade and possibly the .IR file in case there is a format error somewhere.

Hello Binky,

[binky123]

The .IR file is for a URC-8910 so it is not relevant to the URC-8305. The iPod protocol was written for a S3C8 JP1 remote. You'll need a protocol written for a HCS08 JP1.2 remote. If there is a Protocol Builder file for this protocol, they can probably modify it for the HCS08 chip.

RM is complaining that the URC-8305 is a HCS08 JP1.2 remote which is not compatible with the 01 FF protocol(S3C8).

Give this a try. I learned this protocol as well as the S3C8 version and they look identical.

This post here has the HCS08 protocol needed for the 8820.

Thanks blinky, but it doesn't work as expected.
In fact i'm trying to use lirc on a mac mini. It looks like the mac mini receiver recognizes only the apple remote protocol.
I have a 8820 so i'm trying to generate some apple remote codes on my 8820 to make lirc learn them.
With this protocol upgrade and this devices upgrade :
Upgrade code 0 = 0F D0 (Video Acc/2000) Apple iPod Remote for Universal Dock (RM v1.68)
FF 00 7E D2 0E D5 77 E1 C2 50 30 A0 60 90 A1 C0
60 90 30 50 C0 A0 A0 A0 91 61 A0 90 60
End

Lirc learns the remote but finds that all keys have the same code. So there's something that's not right.
Did i do something wrong?

Note that when i learn the apple remote keys with my 8820 i can replay them without issue, but IR 7.06 doesn't want to download them and stops with an error.
Here's my ir file after the download of the learned keys:

There may be some format issues or data it doesn't understand in the Learning section. Open up your .IR file and go to the F000: address and change all of those characters to FF to clear that area of any old signals and re-learn the signals. In that other thread, I was able to learn the iPod signals on a URC-10820 and it looked the same as the S3C80 version.

It could be that LIRC has trouble understanding this protocol? Have you tried using Raw Mode Capture and seeing if the values are different? I recall that WinLIRC had trouble understanding the XMP protocol.

I just tried to use lirc with my urc8820 and the device and protocol upgrade that are in this thread.
I use lirc (linux) on a mac mini (macmini driver) in raw mode.

This is the resulting lircd.conf file:
begin remote

name /usr/local/lirc/lircd.conf.macmini-OFA-raw
bits 32
eps 30
aeps 100

one 0 0
zero 0 0
gap 204000
toggle_bit_mask 0x87EE4306

begin codes
play 0x87EE4303

rew 0x87EE4309
pause 0x87EE430A
stop 0x87EE4306
ffwd 0x87EE4309
frew 0x87EE4306
guide 0x87EE4305
menu 0x87EE4303
info 0x87EE4305
cc 0x87EE4306
prev 0x87EE4305
fav 0x00000000
ch+ 0x87EE4306
ch- 0x87EE4309
m1 0x00000000
m2 0x00000000
+100 0x87EE4309
left 0x87EE4305
end codes

end remote


As you can see, a lot of keys are duplicated when they should not be.
On top of that, when i try to use this file with irw to check if it's good, after each key press on the remote it show the good key in irw AND the STOP key at least once. I wonder if it has a relation with the "stop bit" that has the same value as the stop key.

I'm guessing there's a protocol problem, but really i don't know.

For reference, here's my protocol upgrade taken from IR 7.06:
Protocol ID 01FF
20 15 22 48 31 C7 4D 08 08 01 13 03 57 01 13 01
22 D2 F0 11 A5 08 CA 6E 01 B2 01 63 03 6E 12 B2
B6 63 BE 62 BF 63 A4 FE B7 62 CC FF 5F

Here's my device upgrade:
Type PVR
Setup code 2000
FF 00 7E D2 0E D5 77 E1 C2 50 30 A0 60 90 A1 C0
60 90 30 50 C0 A0 A0 A0 91 61 A0 90 60

I'm not familiar with the protocol or with LIRC. After uploading to the 8820, can you use the PVR/2000 device to control the Mac mini receiver? Forget about using LIRC to record the signal from the 8820. You suspect the protocol doesn't work for your Mac Mini correct?
