TOPIC:

I'm still having real problems getting an infra red remote control to work as a master volume control. I've updated to the latest version (V2.01) and have been trying any random i/r remotes I happen to have in the house. So far I have only been able to get the one for my Cambridge Audio Soundbar to work with my Mini DSP,all others from common names such as Samsung etc just refuse to be learned.
I built a Velleman i/r remote transmitter that doesn't give the specific protocols,but is said to work with most popular i/r receivers.How ever it doesn't work with my DSP box.Any ideas please?

Could you clarify two points:
- There are nanoDIGI firmware versions V2.6, V2.7 and may be later, but V2.01 looks to be earlier?
- The IR remote refuses to be learned or the nanoDIGI does not not respond after learning correctly?

Sorry my mistake I'm on firmware V2.8.

When I go to IR learning and click on learn,the white LED on the Nano flashes for a few seconds and then I get the message "IR remote learning failed".

Have you ruled out other sources that might interfere with IR like neon lights, TV sets, etc? The screen on my Squeezebox Touch interferes with the nanoDIGI and prevents it from learning.

I programmed it on my desk with my Cambridge Audio remote without any problems from a few inches away,it only took a single press of each button for about one second for it to accept the programming.In the exact same position with the IR remote I'd just built,it waited about five seconds to tell me it had failed.

It's a real shame they don't do a hard wired master volume control for this like they do one of the other models,or even one that plugs in the USB port.

Apologies for the question, but have you tested the Velleman i/r remote with something other than the nanoDIGI so you know it works?

What is the Velleman model number?

I can tell it's sending SOMETHING out through the IR LEDs by using a digital camera,although obviously I can't tell if it's transmitting the correct data or not.I can monitor the output on a scope I guess?

Velleman MK162

A scope on the IR LED is one option and I guess you could also probe on the IR receiver in the nanoDIGI. Whether this is worthwhile depends on the compatibility of the MK162 IR protocol with the nanoDIGI. Some threads from a google search suggests it uses a custom protocol:

What's wrong with using the Cambridge remote or the Squeezebox Touch remote (3 years ago) which are working?

I see now that it says the MK162 is compatible with their own receivers,but doesn't necessarily say that it is or isn't compatible with other makes .

This is to be used in my car with my existing steering wheel remote controls and the DSP box in the boot.I have tried soldering wires onto the Logitech PCB but because of the way it's made I just couldn't get a reliable connection.I wanted something like the Velleman kit as I could solder wires on in place of the board mounted switches which would be connected to my steering wheel controls.
I thought this would be an easy way out,but was soooooo wrong.I guess the next thing to try is to build something that is Arduino based that can learn the ones I know work ok.I'm useless with coding,but there seem to be enough ready made solutions that should do what I need.

I had a similar problems.
