One year on from the initial release of AnalysIR, we have provided a copy below of our recent update for the original crowfunding campaign for AnalysIR.
We have been updating the AnalysIR documentation for the upcoming 1.0 release and realised that AnalysIR now decodes 40 Infrared protocols. Wow!. Along with the most common TV & media remotes controls there are 14 Air Conditioner protocols included. The full set of protocols is included with the latest ‘dev’ release, which is available to all current & new owners of AnalysIR (less the aforementioned documentation) in advance of the pending 1.0 release. The 1.0 release will incorporate over 170 new features, updates and fixes compared to the initial release and also supports our new IR Learner which will be launched along with a range of Infrared kits in the coming months.
Here is the latest list of Infrared protocols supported by AnalysIR. Continue reading
A new user of AnalysIR from the Netherlands, wanted to get the AnalysIR firmware working on Teensy 3.x . Although this has not been officially supported, we were happy to support his efforts knowing that it would most likely be a relatively easy exercise, based on past experiences. Needless to say, he was successful in decoding Infrared signals with AnalysIR within a short space of time. Prompted by his interest, we ordered our own Teensy 3.1 to add to our growing collection of 40+ MCUs and although Teensy support is in beta for now, it will be oficially supported for AnalysIR from our next release. In the meantime, users of AnalysIR can just contact us for a copy of the Teensy sketch (firmware).
Teensy 3.x now joins a long list of devices supported for use with AnalysIR, including: Continue reading
Anyone who has tried controlling an Air Conditioner unit using an Arduino, USB IR Toy, RPi or any MCU will know how difficult it can be to record the longer infrared signals they use. Typical TV systems use IR signals circa 32 bits long, while this Chigo AC unit uses a signal with 197 marks & spaces (or 97 data bits). One of our users, Sertunc – from Istanbul in Turkey, reported his success using AnalysIR to easily record the signal timings for his AC unit and sent us the details along with some nice photos. After testing the validity of the recorded signals using an Arduino, he then set about loading the signals onto his Samsung smart phone (models S4, s4 mini, S5 and more supported). This was helped by installing the free ‘Samsung IR – Universal Remote‘ app onto his phone via Google Play.
Our recent post about the silver bullet IR receiver proved very popular and we promised that we would follow-up with another variant of the poor maker’s Infrared receiver. This time we are using an IR Led (emitter), 2 resistors and any standard Arduino. You will also need to download the Arduino code provided below, compile and upload it. One of the most common problems encountered when trying to decode IR signals is that makers don’t always have the appropriate IR receiver for the job in hand or have to wait for one to be delivered by mail. Here we present an affordable method to allow you to use any IR emitter (LED) as a receiver and as a bonus we are publishing the Arduino code to make it all work.
A while ago we came across a website on infrared remote controls which suggested a simple way to view IR signals using an Oscilloscope. The idea is to use a standard IR Led mounted into a BNC/RCA plug using a spare channel making an Oscilloscope infrared receiver. So we set about ordering the connectors, which arrived in the post today. Another way of looking at this device is as a ‘poor-mans’ IR receiver, but if you have an Oscilloscope to plug it into then maybe you are not so poor after all.
Many electronics enthusiasts will be familiar with how Infrared receivers demodulate IR signals. In this post we show a visualisation of the time lag and distortion of the signals as they pass through the IR receiver for demodulation and noise filtering. Most DIY projects use the raw timings from the IR receiver to decode individual signals. However, not many will be aware that IR receivers can distort the signal timings by significant amounts. Fortunately, common IR decoders take this into account and compensate for timing distortions introduced by infrared demodulators / receivers.
Recently we have been helping several members on the Arduino forum to record and playback their remote control signals from their Air Conditioners. These signals are typically much longer than those of TVs or common media devices. The 2 most popular libraries for Arduino, IRremote & IRlib are excellent, but have some limitations which we have covered in a previous post. In this post we address one particular issue that is proving challenging to users.
Over the last few months we have been regular contributors to the Arduino and other forums, answering questions about Infrared remote control projects. It became apparent that beginners typically trip up on many common ‘pitfalls’. So we decided to list off our ‘Top 10′.
We have been intending to add support for LIRC into AnalysIR for a long time. Recently one of our enthusiastic users, working on his Raspberry PI, needed some help getting Air conditioner signals from his ‘Air Conditioner’ infrared remote control decoded. His preference was for a LIRC based approach as he already had this working for his TV via his RPi using a cool web based interface from his smart phone.
