JP1 Remotes

Hi,

I have installed a 2kbyte eeprom in the URC-6540 remote.
But somehow the remote is still set to 1 kbyte, since it won't use the whole 2kbyte. I heard some remote uses a code to initialize to eeprom. But how do I enable the 2kbyte with this remote?

There is no rdf file for the 6540 remote. I tried to make one, by editing urc-7540 rdf file, but it doesn't work good. Some hex code doesn't make any sense. Is there a document on how to make a rdf file?

Without a valid RDF, how do you know that it's only using 1k?

Did you do a 9-8-1 reset to initialize the EEPROM after installing it, and if so did the LED blink 2 sets of 2 blinks?

There really isn't a good document on how to make an rdf from scratch. IR, however does contain a file about the FORMAT an rdf has to use to work with IR. Someone (Nils?) still needs to append that document to make an rdf RM compliant.

Since you've already changed the eeprom, you'll need to initialize the eeprom. Assuming you used a NEW eeprom (vs removing a 2k from a different ueic remote), you can do that by: Setup** holding down whatever is the "manual programming" key untill the red led blinks twice, then 9-8-1. If it's a used eeprom, you may want to do an IR>advanced>purge>upload, then the setup**, 9-8-1 reset. That'll give you a good baseline (see IR>tools>baseline) to see incremental changes when you do manual programming, one thing at-a-time. That should give you a "virgin" configuration. Save that, you may want to reload it later.

You already know the remotes Model name (You need that for the first line under [General]. In the raw data tab, the first two "cells" should be the checksums. the second is usually the complement of the first. What those entries actually are aren't really important for you, the MCU keeps track of that.
Generally, if it's a s3c80 chip remote, the next 8 "cells" will be the signature. You'll need that for the rdf file name. Those will be hex designations of ascii characters. You can use a hex>ascii conversion chart. As an example, the Millenium 3, "W00" remote has 4D 4C 33 30 4D 4C 33 30 in these 8 cells. referring to the hex>ascii chart, that converts to: ML30ML30 (ML three zero, doubled).

You'll need the hex or decimal keycodes for each of the keys. You'll need to take the remote apart and look at the trace side of the PCB for this. Hopefully, for each button space you'll see an Sxx number printed. The Sxx designations are actually OCTAL format. As an aid, there's a Notepad file at the yahoo files you can do that have the conversions already done for you; all you need to do is type in the actual button names as found on either the opposite side of the PCB, or the corresponding buttons on the outside of the remote. IF an actual physical button is missing from the order in the chart, for now, use <missing>.

For eeprom size, a 1K is $400. 2K is $800

Your specific remote *may* have a "split" signature. GENERALLY, the second half, if split, may be found as "fixed data" at the end of the keymove/macro section. This is more commonly seen with 6805 processor remotes than s3c80 processor remotes.

There, that should give you enough for a start. Once you get this part ironed out, we can proceed with getting more rdf data. It wouldn't hurt to post the initialized eeprom IR dump to diagnosis.

Thanks for replying guys.

When using ir.exe, you can see that memmory from adresses 0400 are not used (FF). Since this remote is a zapper, it has no "numbers". The only way to setup the remote is, channel up, down, voume up and down.
I must see the equivalent for 981.

About the rdf file.
This what I did:

[General]
Name=URC-6540/6541 One For All 4
EepromSize=$800
AdvCodeAddr=$016..$0FF
UpgradeAddr=$100..$7FC
MacroSupport=0
Processor=S3C80
RAMAddr=$8000
RDFSync=3 <-------- I'm not sure what this is
ImageMap=URC-6540.map,URC-6541.map

Ok that part a understood, but now the buttons:

[Buttons]
MAGIC[Setup]=$14, Menu=$13, EXIT=$53, Power=$03 <------ what do the value represent?

[ButtonMaps]
??

[DigitMaps]
??

Anyway a happy new year

I just downloaded a manual for the 6540. It uses 6-digit setup codes using only numbers 1, 2, 3, and 4. I'm not sure if this is going to limit the ability to create JP1 upgrades for it since they all use the standard 4-digit (0000-2047) codes.

It also states that the remote supports learning! Wink
