volume control...

[Mark C . Langston]

Mark,
Does the Pronto let you program abitrary pulses - can you say "2ms
low, 1 ms high, etc. at 39KHz modulation", or does it have to learn the
codes from an existing remote?
If so then we could easily make an alternate code for the SliMP3 that
won't conflict with JVC, but has a similar format, so no changes will be
needed on the player.
For now it'll be only useful if you have a Pronto, but later we could make
it the code for our custom remote.

Well, the answer is yes -- sort of. The Pronto can learn from any
remote, but you can also directly input "discrete" IR codes. These
"discrete" codes specify the pulse frequency and modulation.

The best reference for this is found here:
http://www.remotecentral.com/features/irdisp1.htm

(more general info on the capabilities of the Pronto can be found here:
http://www.remotecentral.com/files/main.htm)

Learned codes can also be displayed -- and modified -- as hex-format
discrete codes.

I know Dan has one as well, and may be better-versed in this than
I am.

Sounds fine. I might go remote shopping to find a more programmable
one, in the mean time.

I'd strongly recommend the Philips Pronto. However, the pricetag tends
to limit its audience. When I have the time (I haven't managed to get
around to this, yet), I'll be sharing a .ccf (configuration file) for
the SliMP3 and the Pronto.

Dean,
To make it transmit codes for volume, you first need to set it up for a
JVC receiver, then set it so the volume controls operate the receiver when
in DVD mode. Like this
S RCVR 0 1 8 ENT
DVD
S RCVR VOL+ ENT

Sounds good.

Note the MAS3507D also has bass/treble controls...

It's on the list... :-)

It's unlikely because part of the IR decoding is currently done in the
Xilinx - it's a rather bad design for legacy reasons (not using the right
pins on the PIC for the right things, the first SliMP3 prototypes didn't
have IR).
Essentially the IR codes have to look "sorta like" JVC codes, WRT to the
width of the pulses, and the measured part being the low part of the wave
and not the high. There are several other codes that would have worked,
except that they didn't implement all of the buttons on the rm-v301.
We are going to have a custom remote eventually, so the plan is to support
our own remote plus one or two standard IR codes so that people can use
3rd party remotes if they want.

Sounds fine. I might go remote shopping to find a more programmable
one, in the mean time.

Hi,
I moved my SliMP3 player away from the computer and into the living
room and I REALLY want volume control, so I'm writing it.
I've found that the IR doesn't respond to the volup and voldown key
presses. I noticed XX in the table in IR.pm. Does this mean that
the remote doesn't transmit volume controls for the JVC DVD?
That would suck.
