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?

Re: Checksum headaches
AS many of the bytes don't change in your signals you can save memory by hard-wiring those bytes into your code...will save lots of RAM. In addition by storing the buffers in Flash, you can store many more signals on most platforms...giving you the option for hard-wiring in all the signals you actua...

Re: Checksum headaches
@chuckindixon I checked the link out and it does not seem to work for me. We have already used techniques like this and more using AnalysIR's built-in reverse engineering tool and checksum calculator, without success.......so far! Based on the signals posted, some of the bytes/nibbles/bits changing ...

Re: Change One/Zero colors
Funnily enough, we implemented that recently when adding annotation to the trace.
Unfortunately, it has not been released yet.
However, If you are happy to work with it 'as-is' I can send you an exe (without install package) ....let me know
