AnalysIR supports PSOC 4 from Cypress

AnalysIR now provides support for the PSOC 4 Prototyping kit from Cypress. Effective immediately users of AnalysIR can use the kit to act as an Infrared source for AnalysIR. The PSOC 4 Prototyping kits are available from Cypress and via their global distributors for just US$4 plus shipping. To use the kit with AnalysIR you will also need an IR Receiver and an optional IR Learner, which can also be purchased with AnalysIR. Initially, the PSOC Firmware is available on request and will be included as part of the installation package in a future release.

Driving an Infrared Led directly from an Arduino Pin

logobutton200x200A common question asked on forums is one about – Driving an Infrared Led directly from an Arduino pin.  Although the answer may be obvious to anyone with at least a basic knowledge of Ohm’s Law, many are confused about how to choose a resistor value for optimum performance. Often, there is a debate about whether a resistor is required at all, given that the AVR pins are rated to deliver an absolute maximum of 40mA on a pin. (Note: All of the quoted specs in the data sheet are for test conditions of up to 20mA on a pin). Of course there are better ways to drive an IR LED with a transistor circuit or even a constant current circuit. However, in this post we consider only the direct drive circuit using a current limiting resistor, as illustrated in the diagram down below.
Make sure to read the caveats at the end of this post.

Video: AnalysIR Demo Batch Infrared Decoding

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

AnalysIR now decodes 40 Infrared Protocols

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.

Teensy now supported for AnalysIR

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).
