JP1 Remotes

The main issue with that cable is that it is a true RS232 voltage level cable. Unfortunately, JP1 remotes need much lower voltage level and the signals are all inverted relative to RS232 standard.

You could in theory, fabricate an adapter to convert the +/- 6V RS232 levels to the needed 3.3V-5V ...

Does the "MikeT" Arduino solution actually count the raw pulses? Or is it yet another demod pulse width solution?
See his own words in the thread 3FG linked. Basically, a timer is configured so the all the edges are registered, with high precision. MikeT's software has three modes: In raw mode ...

[quote="Barf
Having said that, I consider MikeT's solution for the Arduino (which is contained in IrScrutinizer 1.1.0, danke Dir Michael!!) as vastly superior to the IrWidget idea, much more accurate and reproducible captures.[/quote]

Thanks cauer29, your response is very useful, now the issue of Voltmeter's Red Probe going into -ve COM & Black Probe into +ve COM has been solved by replacing the latest driver with the driver supplied by the product manufacturer dated 31 july 07,but still some things are very confusing as ...

Thanx for your posting. Summarizing in my own words: everything works, sending as well as caputuring. It is just that the device + IrScrutinizer hangs after some time. This happens both on sending and on capturing, and seems to be happen independently of communication speed.

Actually.I was able to ...

yes i have the batteries in the remote,i have checked volts using realterm,
http://i62.tinypic.com/o8fjes.jpg
RTS(7) volts showing +5V when i click on Clear it shows -5v
same with TXD(3) when click on Clear Break volts drops down -5v and when pressed Set Break its showing +5v

I think that ...

It would be best to put some series resistance in the cable's Tx and RTS lines to limit the current flow into the remote's ESD protection structures. 330 or 470 ohms should limit the current sufficiently without hurting the rise/fall times on the 38.4K baud serial baud rate ...

Perhaps I should've mentioned that my programming skills are nil. Hardware design I can do, but not programming. Any cool hardware designs that require someone else to write the software, would just go begging around here since we see comments about finding a combo device as useful as a toothbrush ...

(2) a PIC or ATMEL processor that does it all, in which case we could go with the HID driver. Either approach would be cost competitive with using the Delcom chip. This doesn't sound like rocket science to me, but then it never does to those who don't know how to do it. Major issue: Flash uploading ...

OPENING THE REMOTE CONTROL
You will need:
1. a small philips/cross head screw driver
2. a piece of thin, hard plastic (an old credit/debit/store/points card or guitar pick)
3. some time and patience

Important: you will not need to use your hands to separate the halves until the very end of the ...

What does this mean?
I think what is being asked is if anyone is interested in writing code for Arduino platform that would interface to a JP1 eeprom remote, to take the place of a proper JP1 cable.

It could be done. Probably the easiest way to do that would be to make the Arduino emulate a JP1.x ...

A long time ago someone pointed me to the learn format, but I don't know where the post is.
This document describes the learned format:

And here's one that fills in much of the info completely missing from that one:

Head to head learning was always way to difficult for me to do without a helper. I hope tommy gets his parts soon. I already have 2 but i'm thinking of getting a spare as an insurance policy. Seeing the widget draught is making me nervous!!!

I hesistate to mention this, but if you're really ...

Are there any plans to make the IR Widget work under Android with infrared logger which logs infrared signals (and lets you note the particular function on each signal) as well as let you note the manufacturer and model of the remote controlled device?

The software to record what the widget ...

I found the reason why the vast majority of infrared receiver modules have a normally high output when no signal and/or carrier is detected is because the output of the receiver is usually connected to an interrupt line (in many cases, active low) on a microcontroller.

So when constructing an ...
