URC-7780 data transfer problem

[dominique.w]

Hello,
Congratulations to the developers for the already accomplished work.
Sorry for my English, I do not practice enough.
I have a URC-7780 (UEI SW VERSION 1062) since two weeks.
I made an IR signal interface and a serial JP1.2 adapter.
I can decode the IR signal of my 18 years old Sony amp/tuner (protocol Sony12)
I can read and write my 7780 memory with IR.exe (ver 7.00)
I want add a device AMP code 1001 with some functions with Remotemaster (see below).

Upgrade code 0 = 63 E9 (Amp/1001) DW_amp1 (RM v1.73)
CA 0D 01 B0 B0 00
End

After I send the data to the 7780 the device AMP code 1001 is not available.

I made an upgrade Wav file (IRtoWav 1.9) but the 7780 does not recognize it.

Finally I downloaded a little upgrade file by OFA. The audio upgrade was good for the 7780.
I dumped the memory and the new device was recognized by IR.exe. I stored the "new device".
I reset the 7780 with the original data and tried to upgrade with the stored "new device".
The direct memory write has no result (the device is not available) and a wav upgrade file is not recognized.

I suppose the different parts (IR.exe, IRtoWav and Remotemaster) works good.
I suspect an error or some missing info in the RDF file.

I would like to compare the OFA upgrade audio data and the same "self made" upgrade.
In order to do this y need a "wav to hex" decoder/converter soft.

Has somebody an idea ?


Thanks

Salut Dominique,

the RDF for the urc-7780 is incomplete. The following entry has to be added to the [Checksums] section :

Code: Select all

^$400:$402..$BFF

Alternatively, you can download the corrected version here.

Thanks Alain,

The new RDF for URC-7780 seem to work.

I can transfer my new devices to the RC and they are recognized.

Now I can start the reel programming work ...

I suspect that the checksum line ^$400:$402..$BFF in the RDF is incorrect.
After I have learned some buttons on the remote IR was reporting an incorrect checksum at $400. After uploading back to the remote the remote did not function (presumably because it didn't like the new checksum that IR had written)
I found that changing the line in the RDF to ^$400:$402..$7FF solved the problem. It also feels sensible, because it means that the checksum is of the UpgradeAddr memory rather than the UpgradeAddr and half of the LearnedAddr memory.

Hi everybody,

Finally I arrived to program my URC-7780. I am very satisfied with the result but without the JP1 technology and the assistance from the forum the expenditure would have been useless.

I am quiet until autumn 2007, because at this time the DVB-T will arrive in my area.

In order to give a little work to our experts I noted following points:

1: If I affect a function to a normal Shift-Key RM generate a "Key Move" with EFC code in IR. These key moves are not working.

2: For a TV device as example I cannot affect a function to a non shifted key like start, pause End or Play because a non working key move is generated. Finally I used only "Video Acc" and "Misc Audio" devices, and renamed these with the RC.

3: When a key is working on a device I can create a Shift command to this key (using the key code) with IR.

4: Even I don't use the "Menu" button, a Menu function is automatically affected when I use Vol+ and Vol- . Finally the function is on the "Mute" button (see point 5). Take care to affect a non working code to "Menu" in order to control the situation.

5: "Menu" and "Mute" buttons are inverted.

6: "Start" and "Play" buttons are inverted.

7: I cannot change the order setting and devices with IR. I make the changes on the RC and reload the configuration to IR.

8: I cannot program macros with IR (see precedent post) but it's easy to make with the RC when all the devices are working individually.

9: I have not used the learning function from the RC so I don’t know if it works.

Good work

1: If I affect a function to a normal Shift-Key RM generate a "Key Move" with EFC code in IR. These key moves are not working.

This is just a hunch but try removing the following line from the [General] section of the RDF:

AdvCodeFormat=EFC

I think that's causing RM and/or IR to create the incorrect key move format.

[dominique.w]

Hello,

1: I removed AdvCodeFormat=EFC in the RDF.

The result is the same. The moved keys are not working.

2: As I cannot backup the memory because the macros make IR errors (see precedent post), I search a way to dump the complete memory without the control from IR. So I can make different tries and restore memory with the initial data's. Has somebody a solution ?
