Flipper Zero support added to AnalysIR

We are delighted to announce that our industry leading AnalysIR application now includes support for Flipper Zero. Features include capturing signals into AnalysIR over Serial USB via the CLI, Manually importing of single and bulk signals in Flipper Zero Format, manually exporting of Infrared signals into Flipper Zero format for control of the target device. This update greatly enhances the capability of Flipper Zeros devices who also have a registered copy of AnalysIR.

Getting the AnalysIR Update

Existing owners of AnalysIR (All Editions) can request the updated version by emailing your support contact using your registration email address. New owners of AnalysIR will be sent the updated version after Registration. When using with AnalysIR, users can reverse engineer signals, convert to a wide range of industry formats and auto-correct IR signal timings using our signal ‘Clean’ feature.

LearnIR vs Flipper Zero

As existing users will know LearnIR is far superior and better value for IR dedicated tasks compared to the Flipper Zero. Similarly all of our IR modules and shields use higher quality components and features than are available on the Flipper Zero. We would also like to thank all of our users who tested this support update with their own devices.

A.IR Shield ESP8266/ESP32 Tx for AnalysIR with IR Blasters

The latest member of our MakeIR series of devices & kits is the A.IR Shield ESP8266/ESP32 Tx. This shield works out of the box with AnalysIR and is essentially plug & play, with additional custom Firmware options. This shield is a ‘sibling’ to our related TRx shield, and features IR multi-send only vs the send & receive of the TRx shield. The shield plugs into a Wemos D1 Mini (ESP8266) with headers or any pin-compatible clone (e.g. ESP32 Mini D1). Although designed specifically for AnalysIR, users can also upload any sketches that run on the ESP for Infrared remote control projects by customising the included firmware. A.IR Shield ESP8266/ESP32 Tx is built with only the highest quality IR components available and boasts dual Infrared emitters with configurable IR Power. The supplied firmware uniquely supports hardware PWM for sending IR signals (on ESP8266). Continue reading Preview: A.IR Shield ESP8266/ESP32 Tx, a high-end IR Shield

Using AnalysIR with Flirc – Video tutorial

We have posted a brief 4 minute “Using AnalysIR with Flirc – Video tutorial”  showing how to use the Flirc USB device as an Infrared remote control signal source for AnalysIR. The video is available now via YouTube, by clicking the image below. The tutorial covers the semi-automatic method we have used to support this feature, which should greatly enhance the Flirc Device and enable more troubleshooting with problematic signals or just simply as an additional powerful feature for the Flirc device. There is no need to update your Flirc installation or firmware, provided you have the latest revision installed. {See update notes below}

Updated ESP8266 NodeMCU Backdoor uPWM Hack for IR signals

In our previous post we showed how to generate stable IR carrier signals using the ESP8266 NodeMCU module. A feature of the original approach was that the output IR signal was inverted and required some additional circuitry to invert it again before transmission. Since the original post we have figured out a method to output a non-inverted or standard IR signal thus removing the need for the additional circuitry. This is achieved by using what turned out to be a very simple setting hidden deep in the ESP8266 UART registers which is covered below. Like all simple solutions it also threw up some other quirks of the ESP8266 NodeMCU, which were eventually overcome with the addition of a simple resistor. The Updated ESP8266 NodeMCU Backdoor uPWM Hack for IR signals is detailed below – including updated source firmware, new circuit diagram and explanation of the ‘quirk’. Read on….

Sending long AC Signals from Flash with IRremote

One of the most popular projects involving Infrared remote control, is to use an Arduino to control an Air conditioner (AC) system. However, AC signals are usually very long and take up a lot of SRAM on a standard Arduino. Experienced users will go about reverse engineering the AC protocol to make the sketch fit within the 2K Bytes of SRAM. Many hobbyists will struggle, even with the help of tools like AnalysIR to guide them. In this post we cover sending long AC Signals from Flash with IRremote. IRremote (along with IRLib) is a popular open-source library for sending and receiving IR remote control signals with Arduino. The demo code covered in this sketch extends our previous sendRAW example by demonstrating how to store many long AC signals in Flash with little or no SRAM overhead.

Troubleshooting the Big Button Infrared remote control with AnalysIR

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.

A hack for Hacks using AnalysIR

One of our users from Italy, Guido, was tasked with upgrading an old in-house WRC system to allow the team of Sport’s Journalists to access the rack of satellite receivers relaying the various sports events around the building.  The challenge is that all of the STB (Set Top Boxes) are located in a dedicated room away from the Journalist’s desks and it is impractical for them to manually change the stations when working to tight deadlines. Previously there was a system in place to remotely switch feeds, but Guido needed to upgrade the system to handle the ever growing number of devices and Infrared protocols. Luckily, he found AnalysIR during his research to implement ‘a hack for Hacks using AnalysIR‘.

Backdoor uPWM Hack on Arduino for Infrared signals using UART

In this blog post we follow up on our recent article about generation of infrared PWM from the Photon’s UART where we suggested that it may be possible to achieve something similar with the Arduino. In our previous attempt the Arduino was only able to generate PWM at 40 kHz and 33 kHz using the same approach. After some investigations we discovered a new approach which provides an even better set of results using the Arduino’s USART. Yes, we were able to generate 30, 33, 36, 38, 40 , 56 and surprisingly the illusive 455 kHz which was not possible on the Photon (using this approach). Read on for the details. Readers should also study our original series of articles on ‘softPWM‘ for a better understanding of the source code which can be downloaded below.
