Re: Help decoding unique protocol of a toy robot

First of all thanks for the detailed post. It should be straight forward to add support for this protocol. However, some Questions: - what is the make and model# of the remote and robot - Each captured signal seems to have a lost of bursts of data (some repeated). So to zoom in on whether each comma...

Re: Wrong IR Codes Received

How does that work? IR receivers distort the signal timing (because of the way they work). So what starts out as an even duration pulse can be distorted. A good site to get an understanding of IR remote control ( search: sbprojects ir and go thru the menu of topics) How were you able to simplify th...

Re: Wrong IR Codes Received

You should still have a series resistor in your circuit to limit current. (unless you have characterized your emitter circuit - including failure modes as well) Pick a TSOPxxx38 (last 2 digits are the carrier frequency) pick the ones with 5 numbers as they are usually more modern versions. For the W...

Re: Wrong IR Codes Received

Some initial comments...based on a very quick read I presume you are not trying to send & receive simultaneously on the same module. => Turn off the receiver while you are sending and for a little while after that.....~150mSecs approx Put a resistor in line with the IR LED, Start with 10R and yo...

Re: IR signal generation based on hexadecimal code?

Hi Rainer You could try this page we have online to generate NEC signals from HEX https://www.analysir.com/hex2nec.php However, this is from straight HEX. The internal NEC bit order is different from the 35 CA OE F1 represented in the Manual to generate this signal you would enter (nibbles and bit o...

Re: Sending AC on signal to AlpicAir

Thanks for the update. The only thing I can think of is the accuracy of the capture/timings. FYI: Our AnalysIR app can clean these signal so that you are sending a good signal every time. Also, our LearnIR module has our unique Fuzzy Clean technology, which can capture signals to within a few uSecs ...

Re: Sending AC on signal to AlpicAir

It seems from the photo that you have the transistor wired incorrectly (from what I can see) Double check the pin-out of the 2N2222 (you may have the emitter & collector swapped???) (make sure it is a 2N2222...without a P...see below) Also, put a 10R resistor in line with the IR LED to limit the...

Re: Sending AC on signal to AlpicAir

Describe your IR emitter circuit (post a schematic & photo).

Re: about IR LED and sensors

actually, that is what my question is, does the real signal just included the three lines as topic? Sorry I do not understand what you mean by this. is it possible to send any data to? Yes. But it is not really intended for that. IR signals would be relatively slow versus RF. Would you please recom...

Re: about IR LED and sensors

the purpose is to test if I can send that? seems not possible?
Why not test with a real signal?
