I have a dumb question about Cenema 7 memory. I am sure that I will
run out of memory as I have had to do a lot of work to set up to
conrol my Apex AD-600A DVD player. I am now starting to work on my
Denon AVR-4800 A/V Receiver and it is quite evident that it will take a
lot of memory to get it working. I dono yet whethere I even have
enough.

My question is whether there is any way to flush the codes out of the
AUX component area and free up that memory for other uses? In the short
term I do not plan to use the AUX key at all. All of the other
component keys are to be used.

The Cinema 7 has enough memory for 45 buttons programmed using advanced codes (less if you program macros). It also has a seperate memory bank that is used for learning, it can learn about 24 buttons, depending on the length of the IR signal being learned.

To flush out everything that you have programmed, use the 980 command:

[SETUP **] 980 ** **

To flush out all the buttons that you have programmed for a specific device button, use the 994 command:

[SETUP **] 994 ** AUX AUX **

I was not speaking of flushing out buttens that I
have programmed. What I was getting at is it possible to flush out or totally clear a component butten of
any device and recover that memory for use in programming other devices. In other words, would it then be possible to program more than 45 buttens for
other components or macros?

I would guess that the answer is no but it is worth
asking.

Sam,
If you haven't programmed any buttons then none of the memory has been used up. The actual device code information is stored in the ROM of the remote. There are 7 area of data that are used to store the actual device codes and this is the only purpose these areas serve, plus it only takes two bytes to store a device code, it takes five bytes to program a single button.

There is a seperate area used for macros and buttons programmed with advanced codes, this area is 226 bytes long. agian, if you haven't programmed anything, there's nothing in this area.

There is a third area that is used for learned commands and this area is 401 bytes long. Obviously a learned command takes up alot more memory than a simple advanced code, so this is only enough space for around 24 buttons.

Rob.

Thanks Rob,

So the device code information is stored in its
own little bucket, one of seven. I guess that
from what you are saying, these are not part of
a pool and could be recovered and used for other
purposes. I was afraid of that but I had to
ask. Thanks much!

You got it, Sam. There are only two user memory areas, and they don't include the stored device/function codes.

Then again, it's a <$30 remote. Buy two!

So far, I've been able to learn 33 buttons on the C7.

At first I only got about 20. Then I did a 981 reset, which I believe set it back to factory defaults. Then I took the "tap instead of hold for 2 blinks" advice, which made a big difference. This is when you're doing the learning process on the C7 and the manual says to hold the old remote's button until the C7 blinks - DON'T - Just tap the old remote button and the C7 will most likely still learn it.

But then I discovered while expermenting with the reset that the factory default operated my TV without any code input and I think I was actually able to pick up a couple of extra learned buttons by not programing in a tv code.

Now I suppose that could have resulted from doing quicker "taps" during my last learning process - I'm not sure. All I know is that my last try did give me at least 2 or 3 more learned buttons over the previous round (durning which I was also doing the quick tam method). Anyway, I think I'll leave well enough alone.

Hope this is useful to someone.

<<But then I discovered while expermenting with the reset that the factory default operated my TV without any code input and I think I was actually able to pick up a couple of extra learned buttons by not programing in a tv code.>>

If you were able to get more buttons learned it was due to your learning technique, not the fact that you used the default TV code. Like I said earlier, there are 7 two byte fields in a totally different part of the memory that are used to store the device codes. When you do a factory reset, these fields will return to their default values, but they still hold a value regardless, and you can't access this space for learning and/or advanced codes either way.

Just to give you an idea of the amount of memory used for each operation, there is a total of 14 bytes put aside for storing all 7 device codes. A learned command will use up anywhere from 30 bytes to 50 bytes depending on the signal being learned and how it was learned. Each button programmed with advanced codes uses up 5 bytes of memory. Each macro uses up 2 bytes plus 1 byte for each keystroke, so an 8 keystroke macro would use 10 bytes of memory.
