Marco is a volunteer for an organization (NSW Australia) that builds custom aids for people with disability, and has recently been looking at a project to create a ‘very large button’ IR remote control for a cable TV Set Top Box (STB). The custom unit needed basic functions (Channel Up/Down, Volume Up/Down and Power On/Off). Commercially available large button remotes have buttons that are still too small and/or they have too many buttons. Soon he hit a roadblock trying to capture some difficult Foxtel signals and searched all over the web looking for a solution. Needless to say, nothing worked out for him until he came across AnalysIR via Google. Once he started Troubleshooting the Big Button Infrared remote control with AnalysIR the root cause of his problems became obvious.
In recent years we have responded to hundreds of supports requests on the Arduino Forum, GitHub and elsewhere for many recurring issues with IRremote – the library for Infrared remote control. As many of the issues are similar we decided it was time to develop a ‘IRremoteInfo a Helper utility for troubleshooting IRremote’ that will help users resolve their own issues or failing that, provide solid support information to those who are providing free support services. Today we release the first version of IRremoteInfo, which prints the settings for most of the relevant parameters within the IRremote library, in the hope that users seeking support can post or upload this information when seeking assistance on-line.
IRremoteInfo a Helper utility for troubleshooting IRremote
We have just launched a short 11 minute AnalysIR video tutorial introducing the use of the Reverse Engineering Tool feature in AnalysIR, which is available via YouTube. The tutorial covers the important points in reverse engineering in infrared signal of a Toshiba Air Conditioner. We focus in on the temperature field and show the process to identify the bits within the signal related to the temperature. Users of AnalysIR can follow this process to reverse engineer their own signals using this powerful tool.
Dublin, Ireland – 27th August 2015. We are happy to announce the latest release of AnalysIR V1 preview #3 is now available for download by our backers & supporters. Existing users of AnalysIR will receive an email with instructions on how to download this version. New users will receive the details as part of the registration process.
A major highlight of this release is full AnalysIR support for our soon to be released A.IR shield. A.IR was designed to function as a high-end input/otput IR device for AnalysIR and will also work with IRremote, IRLib and any other Arduino sketch. More details will be published soon.
We have just completed porting our (single source) firmware from a range of other ‘Arduino’ type platforms to Particle’s Photon, having received it yesterday & thought it would be useful sharing some of our experiences for other ‘newbies’. The photon is one of a breed of modern IoT devices hitting the market at relatively low cost. It features a STM32F205 120Mhz ARM Cortex M3 processor running at 120MHz with 1MB flash, 128KB RAM and the all important WiFi. We have been wanting to support the previous Spark Core ($39), but couldn’t resist this little device at the low price point. Particle are also offering a similar embedded device in larger quantities of 10+, for $12, including FCC certification.
We are often asked on discussion boards, about conflicts between IRremote or IRLib and other Arduino Libraries. In this post, we present a sketch for ‘Simple Infrared PWM on Arduino’. This is the first part in a 3 part series of posts. Part 1 shows how to generate the Simple Infrared PWM on Arduino (AKA carrier frequency), using any available IO pin and without conflicting with other libraries. Part 2 will show how to send a RAW infrared signal using this approach and Part 3 will show how to send a common NEC signal from the binary or HEX value.
Dublin, Ireland – 17th April 2015. We are happy to announce the latest release of AnalysIR V1 preview #2 is now available for download by our backers & supporters. Existing users of AnalysIR will receive an email with instructions on how to download this version. New users will receive the details as part of the registration process.
A major highlight of this release is full AnalysIR support for our soon to be released LearnIR (IR Learner). LearnIR delivers the best performance available for receiving and sending Infrared signals with excellent accuracy.
Recently, two of our users in France (Vincent & Mathieu) collaborated to reverse engineer the Panasonic AC Infrared protocol, one of the more challenging AC Infrared protocols using AnalysIR. Not only did they identify the codes & checksum but also provided some impressive documentation and full source code to help others. Detailed information is available via GitHub which is linked below. This 216 data bit Panasonic AC Infrared protocol is composed of two consecutive frames. The first frame remains constant for every command sent to the AC unit. In common with most AC units the complete configuration is sent with every IR signal (temperature, fan, swing etc…). AnalysIR was used to record and turn the signal into HEX/Binary format from which the reverse engineering of the individual fields was tackled.
Here we show a screen capture demonstration of the ‘Batch Decoding’ feature of AnalysIR. We show Infrared signals from 4 different Air Conditioners and how we can load them into AnalysIR and execute a batch decode of all of the signals in one easy step. Included are signals from Panasonic, Vestel, Fujitsu & Daikin
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 15 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.
