Re: Using a Pi for transmitting IR signals

...nice

where exactly is the error now? in the PWM signal or the mark/space timing. It is OK to set the carrier to 33% duty cycle instead of 50%, if that helps.

With AnalysIR, you can 'clean' the signals via Menu->Power Tools->History Clean

Re: Using a Pi for transmitting IR signals

one approach that might improve your timings.... - when sending a marks and spaces...keep a running total of the time since the signal started and synchronise the start and end of marks with that. - if you continually do a wait for the mark & space durations then you will get a cumulative offset err...

Re: Signal not recognize by AC (with LearnIr)

Hi Javier there is something wrong with that capture. It is a long signal in 2 parts with all 0's. So if you record a full set of signals and email them to me I will have a closer look. (On AnalysIR Menu->File->Save Session ) - include temperature from 16->30degC plus Power ON + OFF - record them in...

Re: Using a Pi for transmitting IR signals

Yes the Pi runs Linux which is not usually a realtime OS. So you will always get small time offsets which will impact IR sending. That is why LIRC uses the kernel. FYI: our A.IR shield Nano (see our shop via link above) comes with a python script for sending and receiving on RPI (and other platforms...

Re: SHARP AC / Air Conditioner successful decoding with AnalysIR

This thread is amazing to get some information about air conditioner. SO if you controle your air conditioner then you must use an application by this that will be done properly. You can write your own firmware for Arduino platforms or similar. You can also use exiting libraries like IRremote (see ...

Re: Constant current IR LED circuit

Great, thanks for the update.

That is the kind of performance you can get with our SendIR modules. (Available via our online shop & actually, they are even a bit better!)

Re: Constant current IR LED circuit

Post a photo of your circuit, with connections & resisto values clear. (If the changes below don't work) One possibility might be....the 3k3 resistor could be limiting current dependinf your NPN. So lower the value of R3 to 330R. Changing R4 (with the above change) to 2R, should provide the same out...

Exporting AC signals in Pronto Format from AnalysIR

A user raised the following question: I am working on a Raw IR Codes Provided by a Manufacturer. I want to Convert this Code to Pronto Hex to make it work with my Thermostate to fire it. I have tried using AnalysIR but cant figure out how to do it. So we decided to share the answer to help other use...

Re: getting started with decoding Non standard signals

Question 1) Does this mean a digital 1 one is Mark+ space(1) and a digital 0 is a Mark +space(0) and the pulses represent the digital 1 and 0 respectively the numbers seem to add up more or less Yes: M450,S1250 => 1 & M450,S450 => 0 (Although this is usually the way, it could also be the opposite, ...

Re: Automatic AC Temperature Control

Try this sketch from our blog to record your signals. https://www.analysir.com/blog/2014/03/19/air-conditioners-problems-recording-long-infrared-remote-control-signals-arduino/ Also, make sure you AC is OFF before trying to turn it ON! You can adjust any signal you have using the timings I provided ...
