ESP8266 NodeMCU Backdoor uPWM Hack for IR signals

We received our ESP8266 NodeMCU several months ago it has been difficult to find a working example of Hardware PWM to generate crisp Infrared carrier signals. Most posts we have read suggest that there is no PWM readily available on any of the supported platforms. As we have already shown with Arduinos and the Particle Photon we figured it would be possible to use a spare UART pin on the ESP8266 NodeMCU to achieve our goal.  After some initial success we encountered some watchdog timeouts/resets and it seemed like the uPWM hack would not be possible on the ESP8266 Node MCU platform. For a few weeks we ‘parked’  the effort and today we decided to try again with all of the latest and updated firmware available from the ESP8266 community via the Arduino IDE. This time we were successful and the ESP8266 NodeMCU Backdoor uPWM Hack for IR signals using works!

Preview: A.IR Shield Photon, a high-end Infrared Shield for AnalysIR

The final member of our first MakeIR series of devices & kits is the A.IR Shield Photon. This shield works out of the box with AnalysIR and is essentially plug & play, with additional prototyping options. The shield plugs into a (Particle) Photon with headers or pin-compatible clone. Although designed specifically for AnalysIR, users can also upload any sketches that run on the Photon for Infrared remote control projects by customising the included firmware. A.IR Shield Photon is built with only the highest quality IR components available and boasts dual Infrared emitters with configurable IR Power. The supplied firmware supports hardware PWM for sending IR signals.

AnalysIR Video Tutorial – Reverse Engineering Tool

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.

AnalysIR Video Tutorial – Checksum Calculator

We have just launched a short 6 minute video tutorial for AnalysIR introducing the use of the Checksum Calculator feature in AnalysIR, which is available via YouTube. The tutorial covers the steps to verify the position and type of checksums that are typically found in Air Conditioner infrared signals. The types of checksums covered include:

  • XOR
  • SUM
  • CRC-6
  • CRC-16
  • …for both bytes and nibbles.
