Re: Convert LIR to RAW format

Hi If you had a copy of AnalysIR, you could do this in bulk. Other wise the main option would be to use The LearnIR app as you know. I could email you a python script that will convert from LIR to RAW. You can easily adjust this, if you know a little Python. I guess you could also port it to C if in...

Re: Minimal Code (python) using Rasberry Pico

Ir signals are made up of marks & spaces. In your signal the negative values are spaces. Tje non-negative are marks. A space is essentially no IR is sent. A mark is sent as a modulated(PWM) signal. see https://www.sbprojects.net/knowledge/ir/index.php There are many pages of info under the menu....

Re: Minimal Code (python) using Rasberry Pico

Unfortunately, we don't support the RPI PIco at this time and would try to avoid using python (vs c). The good news is that I imported your signal timings into AnalysIR and it decodes as Mitsubishi 288 AC signal. Based on a quick read of your code you are not providing any pwm to the carrier on the ...

Re: Constant current IR LED circuit

Okay good to know. So as long as the power source can provide the amperage I could add even more LED? IN this circuit it is also about voltage drop. With a Vcc of 5V you can easily put 2 IR LEDs in series (a 3rd might be an issue). regarding your schematic.... You should have a resistor on the emit...

Re: Constant current IR LED circuit

I used a TIP120 as transistor, apart from that just like your circuit and a LD 274-3 IR diode. Double the output? Couldn´t I get more power to each LED in a parallel circuit? If the leds are in series and connected to 5V, then the same current goes thru both. If you only have 1 LED in series there ...

Re: Constant current IR LED circuit

I rebuild your "one LED version" circuit (thanks for this work and inspiration!) but as a electronic clumsy I was wondering what the point of the R2 actually could be. I am currently driving this one with an ESP32, so available current that can be drawn is limited but at which point this ...

Re: Decoding AC Signals - Beginner Questions

For sending Hex values are you referring to this blog try this one https://www.analysir.com/blog/2016/04/11/sending-long-ac-signals-flash-irremote/ Basically, do I have to build my own protocol to send Hex values instead of Raw Data? Yes you would have to customize the code above or similar. Second...

Re: Decoding AC Signals - Beginner Questions

Questions: 1) I can't make sense of the value in AnalysIR for example changing the temperature to 18C? What is the first value (1;0;1000;0) ? and how it correlates to the actual raw data, it seems they don't match. 1;0;1000;0|2;1000;3280;1|3;4280;1692;0|4;5972;400;1|5.....etc.. vs Raw (259): 3280,-...

Re: Any special tricks for Sony protocols?

Yes

SONY codes usually need to be sent 3 times with a gap(try 20-40ms). Did you try this?
