JP1 Remotes

[mtakahar]

Another question. Do you know what the default device is when the remote got reset? Even thought the activation setup code is TV/1800, you should just press a volume key in the default device when you activate the extender.

I was assuming the default was Cable, but the following line may have to be changed if that's not the case:

Seeing as how this is the OEM remote for a DCP501 a/v system, I would assume that the default mode is "audio".

Thanks for the great information, Hal. I only had time tonight to test the blink protocol/upgrade. It worked as advertised, except that "4" blinked 3 times and "3" blinked four times. The first blink on each key was longer than the others, maybe like a double blink with no off time in the middle. A 981 reset gives two sets of two blinks with a short pause between sets.

Thanks!

Gotta go soothe the baby...

When I saw a word "normal", I guess I was automatically thinking it's in IR, even though you explicitly said "on the remote". Perhaps this is a symptom of JP1 addiction.

Based on your observation of device selection not working at all, I found a problem. I forgot to change what the 1st device index was.

[joshville]

I tried the new file, but still no device selection. I tried assigning a macro for the sequence "1-2-3-4" to the "A" button, but it didn't work either.

Also, there is some strange behavior after the upload to the remote. If I press any of the device keys (before pressing a volume key), the lights under the device keys go through their little sequence show the same as they do when you're manually, on the remote ( ), changing the device code for that key.

After initializing with a volume key there is also some strange behavior. If I press only volume keys I get an alternating pattern of no LED response and the 1 long 3 short that I get when initializing the extender. Like:

Press [no blinks]
Press [1 long 3 short blinks]
Press [no blinks]
etc.

I can press any number of non-volume keys and I get a normal single blink of the LED, but then if I press a volume key afterward I get the 1 long 3 short pattern again.

I also have a question about the programming. I've been trying to go through the ASM file line by line to try to deconstruct what's going on. I was trying to check the differences between JR, JRNE, etc, but didn't find JRNE in the processor instruction set referenced by Rob in the previous post. Is it in a newer/different version of the processor? or some undocumented function? or am I just way over my head? (most likely scenario)


Thanks!

Dang, I've been looking at too many different files. Now that you mention about the s3c8asm file, I do recall reading that before. It just didn't sink in to the proper portion of my memory bank. Time for me to RTFRM again.

Your blink testing protocol/upgrade worked again as it was supposed to, with the 3 and 4 transposed. Volume, mute, channel all blinked the appropriate number of times.

I changed the line in the 1800 protocol you suggested. I assembled the asm file and then merged the hex file with the beta 4 extender in IR. After upload the behavior is the same as before, except that any key will activate the extender. The volume buttons still do that alternating 4 blink/no response sequence as before. It's still only the volume or mute that does that, though. As far as funny LED behavior, here goes.

There are 9 LEDs, one under each device button (both real and fake). Unextended, the light under the active device blinks with each key press that is part of that device key set or punch thru. I believe there are several keys in addition to volume that are punched through to Audio by default. The device button lights for both the real device buttons and the fake ones.

Code setting procedure on the remote is holding the desired device button down until all of the programmable device buttons light in sequence:

CATV, AM/FM, TV, VCR1, VCR2, CATV, AM/FM, TV, VCR1, VCR2,

The desired button then remains lit until a code is entered. A good code is acknowledged by 3 blinks. There is a slight delay (0.5s?) between the press of the last key and the acknowledgement.

All of the device buttons (real and fake) remain lit when held down until the sequence begins (real only). The exception to this is the TV button, which only blinks on then back off until the sequence begins.

The only other quirk in unextended mode is that the record button only lights the LED on the second press when in VCR mode. I tried that with a couple of setup codes. Pressing another key after the first press of the record button resets it to a non-pressed state (i.e. you still have to press twice for a blink)

Immediately following an extender upload, pressing any real device button except TV gives the light sequence CATV, AM/FM, TV etc. A code may be entered after the sequence without loading the extender. After either code entry or press of a non-numeric key, the next press of a number, volume, or channel loads the extender. The previously hit device key does the 4 blink pattern and all ensuing key presses in the Cable keyset light that button.

I know this is pretty verbose, but I wanted to give you all the information I had.

Thanks!

I found and fix at least one place that would cause all sorts of problems. Bad news is the fix made the extender chunk size one byte too many to fit into the $01A - $0FF area (so called "old keymove area", which is not going to be used in this remote without the extender.) So, I had to rearrange the code and as a result, the available EEPROM space became a few dozens smaller than the previous one because the code can't be rearranged just arbitrarily. Once this extender starts working, you could reclaim this space for handling a few more key sets or something else if you are looking for more fun. (hint: see the 6131 extender)

I've corrected the buttonmap section in the RDFs, including non-extended ones in this archive.

It looks like that fixed at least some of what was going on... I still get the four blinks with every volume key press. Device selection doesn't seem to be working completely. However, I assigned macro "1;2;3;4" to the "A" button and it worked. Pressing a real device button also illuminates the LED for the device button that was active at the time of extender initialization, after which no buttons will light it again except another device button.

When the extender loads it works my cable box, regardless of the settings I have in the Device Buttons section of the General tab in IR. After a device button press the remote doesn't respond (no LED blinks and no effect on my equipment) until I hit the CATV device button, after which it controls my cable box again. The exception to the previous sentence is when I hit the "A" button with a macro assigned to it. The LED blinks sort of longish (probably due to the macro length). It sort of seems like it's not finding the device settings?

Thank you again!

Could you try commenting out all the occurences of calls to LedOn, LedOff and CheckVolKey and if it makes it any better?
If it seems to work, then put back one thing at a time and see where it breaks again.

Thanks for catching the RDF bug Hal, I have updated the 3 RDFs that are in the RDF folder.
