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.

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.

ESP8266 NodeMCU Infrared decoding added to AnalysIR

A few months ago a new user to AnalysIR, from Canada, asked us to assist in adding ESP8266 NodeMCU Infrared decoding over WiFi into  AnalysIR. We set about making some upgrades to AnalysIR for this and in double quick time he had AnalysIR accepting IR signals from the ESP8266 over WiFi. He stressed the ease of use of the support within the Arduino IDE for ESP8266 devices and he wasn’t kidding. This motivated us to go and order an ESP8266 for US$3.60 including shipping from Aliexpress. Just the other day the NodeMCU arrived, presumably  delayed somewhat by the extended XMAS holidays & celebrations, in this part of the world. So we set about porting our existing firmware for Arduino & Photon over to the new device.

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.

IRremoteInfo a Helper utility for troubleshooting IRremote

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.

Backdoor uPWM Hack on Photon for Infrared signals using UART

Since we received our Photon several months ago it has been difficult to find a working example of Hardware PWM on the Photon. Initially, we ported our softPWM approach to the Photon, which is excellent. However, we figured it must be possible to use at least one of the spare UARTs on the Photon to achieve our goal. So first we started prototyping on the Arduino and quickly got a working example with some limitations – only 40 kHz and 33 kHz carrier frequencies were possible with the UART without delving into the registers a bit more. Then we moved the code over to the Photon, leveraging our previous softPWM examples, upgraded with the Arduino code – EUREKA! The Backdoor uPWM Hack on Photon for Infrared signals.
