JP1 Remotes

[ianc2674]

Howdy.
I'm looking for a way to convert the data found in the .rmdu files into a format suitable for the arduino library IRremote ( http://www.arcfn.com/2009/08/multi-protocol-infrared-remote-library.html ).


This is the code I want to use.

Description=Canon Camcorder WL-D88 Remote
Remote.name=URC-6131(Old) PVR Remote 2K
Remote.signature=PVR0PVR0
DeviceType=VCR
DeviceIndex=2
SetupCode=1167
Protocol=00 5A
Protocol.name=NEC2
ProtocolParms=131 227 null
FixedData=21 3E 38


this is the button I want to use

Function.7.name=Photo
Function.7.hex=F3


and the arduino library format looks like this...


irsend.sendNEC (0xA16E0CF3, 32); (Canon WL-D77 remote photo button)


I was able to get the canon d77 remote code directly from the physical remote, but I don't have a d88 remote for my other canon camera.

I've been plugging various guesses to test but not getting anywhere. Any ideas?

Thanks.

The correct way to do this is to download RemoteMaster and open the rmdu file. It then tells you the device.subdevice and function (OBC) numbers. I've done this for you:

NEC codes are 32 bits, and NEC is used in most Canon cameras. So I doubt that is the problem.
I checked to see if I had made a calculation mistake: I loadid the D88 upgrade into a remote, learned the resulting signal, decoded it into the same basic format as the Arduino, and it says 0xC1C70CF3. So I don't know what is the problem. Are you sure that a D88 remotes should work?

Yep, almost all canon cameras use Nec protocols. We do have a few canons (Rebel, ESOS) that use that weird 1 bit protocol, but that doesn't apply to camcorders.

I'm kind of interested in the Canon WL-D77 remote photo button that the OP posted. Isn't irsend.sendNEC (0xA16E0CF3, 32); show that this is 133.59? Or did I miscalculate? AFAIK we don't have any upgrades with that combo. Shutter is the same OBC as shown in the WL-D88 .

ianc2674, can you confirm the remote, or give us the camera model number?

Tip: When creating an upgrade, always include ALL functions from the oem remote, even if you never plan on assigning them to a button. Complete function lists makes an upgrade more helpful to others.

The code given works. I had not realized they put the IR sensor on the viewfinder and not the front of the camera! RTFM.

There is also an option to turn off the remote control on this camera and probably other canon's, so anyone else who is testing ir on canon camcorders, remember to check your menu for that option.

Thank you for the help!

Thank you for posting the follow up.

Let's take photo first. The OBC is 48 or 30 in hexadecimal. Reversing 30 gives 0C, which is the 3rd byte of the signal. The NEC protocol calls for the 4th byte to be the binary complement of the 3rd byte. XORing 0C with 0xFF gives 0xF3. Another way to calculate is 0xFF-0x0C = 0xF3.

So for record/start/stop, the OBC is 3 or 0x03. Reversing gives 0xC0, which is the 3rd byte, and the 4th byte is 0x3F.

I always find that it's easier to build this sort of thing into a spreadsheet:
