Well another truly amazing day – have now reached 60 backers for AnalysIR.

Today we tested out the new export feature with one of our backers who had lost a remote control for a cool RGB light, but had previously recorded the NEC (extended) codes using IRremote. As a first test of the new export facility, we were able to read the NEC codes into AnalysIR & then export them into Pronto format because our backer had a smart-phone app & IR blaster that only takes Pronto codes as input.rgblamp


Getting the codes into AnalysIR was easy, because we happened to have a similar remote in our collection, which had many of the same codes. Otherwise we would have used an Arduino IR library to generate the IR signal for AnalysIR.

What was really impressive is that this all worked first time. Happy us & happy Backers.

We hope to do similar tests with all the other export formats this week, including Global- Cache commands.

Finally, a big welcome & thanks to all our new backers!

Update: Bonus feature – IR Chart Analytics for AnalysIR

Today we have added another bonus feature to AnalysIR – a colour coded chart which displays the distribution of Marks & Spaces of an IR signal, including an option to select the granularity of each time slot measured (from 10 to 1,000 uSecs). We have included a screenshot below of an NEC signal at 50 uSecs time slots and the chart shows the number of Mark/Spaces for each time range found.

This feature has a number of potential uses:

– Makes decoding new protocols easier, because you get a quick analysis of the pulse lengths (marks & spaces) in the signal.

– Can immediately show problems with your IR receiver, transmitter, encoding or decoding circuit/logic. For example, in the chart above the space for a ‘1’ bit should be 1,690 uSecs and it’s shown on the graph as being spread out between the 1550 to 1700 time slots. This is not normally a big issue as most decoders will allow a reasonable margin of error when decoding, but it can help to highlight issues when designing.

– Using the image save option means you can export the chart and use in reports, blogs or presentations.

Thanks again to all our backers who used the IGG referrals option for AnalysIR. It has had a real impact. (We are now ranked in the top 10 Technology projects on IGG which have reached over 75% of target!  – ahead of many bigger projects Keep sharing your AnalysIR referral link.  See earlier post re referrals)

And finally, keep your feature suggestions coming!

Another quick update to let you know that we have also included Pronto code import, as a bonus feature today, in addition to the other 2 formats in the post earlier today.

As we were testing the pronto code import, we came across another protocol from Pioneer based on the NEC protocol, but with different timings. So we also included support for this Pioneer protocol into AnalysIR.  This import facilty is really superb, only sorry we didnt do it earlier 🙂

Apologies, if we missed anyone.
