Thought I would familiarize myself with the IRSliceCreator process for capturing codes before buying the NextWave box (will probably only have a day or two return privileges). So, decided to try the process using my JVC VCR remote - I'm using the JVC as my tuner ATM so someone, somewhere, at sometime was able to capture the JVC remote.

I'm getting there, however, having a few problems,, errr, getting experience...

It appears that in a majority of instances when exiting SliceCreatror I'm getting:

./ irSliceCreator.sh: kill: (nnn) - no such pid

where nnn is a varying process number. So, each time I exit, or have to ^c when hung, I ps auxwf and kill any irlock process I find. Yes, no?

When capturing, things will be going along nicely and then a negative length crops up and SliceCreator hangs.

Got bad length of 1, wanted: 5
Got bad length of 6, wanted: 5
Got bad length of 4, wanted: 5
Got good code of length 5. Good Codes:1 Codes Required:5
Got good code of length 5. Good Codes:2 Codes Required:5
Got bad length of -10, wanted: 5

The negative length seems to appear more when not capturing in total darkness but still happens. At that point what ever key I was capturing, if I've gotten any good codes, there will be a partial .cap file. I've been deleting it when trying to recapture the key. Yes, no?

Frequency. I think I know that the JVC remote is 40khz. This is from some web information about JVC remotes, from some Pronto info and from an experiment I built. I've built a small test rig with an IR photodiode and have taken a look with a CRO (not a DSO) at what the JVC remote does. Hard to be conclusive, but knowing/believing the frequency to be 40khz I can then find a periodic wave at 40khz. So, my question:

After capturing I used option 2, Determine Frequency of Remote, and _all_ frequencies seem to work, that is they change the channel on the JVC VCR, except 33.. So, 31 works, 33 doesn't, 43-67 work.. what gives?

And last but not least, there isn't a SliceCreator option for 40k. I can enter 40k either in Option 0 or on the command line,, should I use 40k if I think it's correct?

I was able to capture all keys and then found that 4,5,8,0 don't work when I tested them. Recapturing those 4 keys tonight (darkness).

This is fun! (but then again, I don't get out much.. lol)

Cheers,
