JP1 Remotes

Hello,

i read the guide to create a new rdf file ...

... Now i want to create a new rdf file for URC-7530 (3 devices: TV, VCR, AUX).


>>step1:
>>First off, take a backup of the remote's current memory.

here's a backup of the remote's current memory (Eeprom 24C08, $0400, 1024 byte):
http://www.hifi-remote.com/forums/dload ... le_id=3010

Here's an image of the remote (image of the board)

(328kB)

>>step2:
>>Next up, let's figure out the remote's signature. Skip the first two bytes
>>in the dump as these are a checksum, the next 8 bytes (from $002 to $009)

signature (from $002 to $009) is:
SER0#### (# are cryptical, and non human readable characters)



>>step3:
>>Next up, let's figure out the setup code buckets

setup code buckets:
000D: (TV)
000F: (VCR)
0011: (AUX)



step4:
>>Now, you need to figure out where the keycodes section
>>starts. So, first off, do a 981 style reset

995 'learn macro' and 981 is not possible with the URC-7530. Instead 981, i made a 980 reset.

After making a keymove (magic/994/3/1) moving 'key3' to 'key1', the
keymove section starts at 001A.



step5:
>>Next up, let's get the keycodes for the
>>buttons (to be used in the [Buttons] section)

Power CC
Vol Up BC
Vol Down B8
Channel Up 7C
Channel Down 78
Mute C8

1 F8
2 F4
3 F0
4 EC
5 E8
6 E4
7 E0
8 DC
9 D8
0 FC
10(-/--) D4
20(AV) 1C

Rewind (TextOn) 0C
Play (TextOff) 00
Fast Fwd (TextExpand) 50
Pause (TextHold) 58

TV/VCR (red) 20
Stop (green) 24
Rec (yellow) 34
Slow (blue) 2C

Thanks for help.

This IR dump is suspect due to the fact that it has the exact same signature as your other remote. Could you please go to the "Advanced" menu in IR and select "Initialize to $FF". Then after you've initialized the remote, do a 981 (not 980) reset and load that file up for me to see.

>>do a 981 (not 980) reset and load that file up

Five days ago, a 981 was not possible (there was a single blink, and not a double blink), but today,
i got a double blink and the reset was successful (i don't know why i got a single blink 5 days ago ).

The signature is EMAIEMA0 now.

Here is the new upload:

step4:
>>Now, you need to figure out where the keycodes section
>>starts. So, first off, do a 981 style reset

A 981 reset is done. Macro (995) is not possible with the URC-7530. -So i made a keymove(994).
After making a keymove (magic/994/3/1) moving 'key3' to 'key1', the
keymove section starts at 0016.
0016:15
0017:23
0018:10
0019:25
001A:F0 (F0 = "3")
001B:00

Then you should be able to use the standard URC-7540 RDF that's included in the main zip file.

EMAIEMA0 (URC-7540_7542 One for All 4).rdf
