Re: Flooding a room with IR

Ok So a good IR receiver would be TSOP34438. This along with the suggestions above should be OK. When using NEC, if you can use less than the standard 32 bits...say 24 or 16 bits then the performance should be better. you only need 24 bits for full RGB coverage (vs 32 for NEC standard) In most situa...

Re: Flooding a room with IR

If you post the type of signal you are sending (protocol, #s bits & carrier frequency) I can suggest a good receiver.

If you post a reasonable textual summary of the use case of your project, I may be able to make some helpful suggestions.

Re: Flooding a room with IR

What do you mean a 12V supply ONLY to the first LED? In the circuit mentioned where the 5V connects to the first LED...if you connect it to 12V instead, you can put up to 6 IR LEDs in series. The rest of your circuit can be 5V or 3V£ levels. Alternatively, our SendIR module (via our webshop) comes ...

Re: Flooding a room with IR

As a first step I would try 2 different LEDs with different angles. If that does not work, try multiple pairs of LEDs to give more coverage. If that does not work...using a 12V supply only to the first LED, would allow many more IR LEDs to be connected in series. Please provide more detail about wha...

If you post the file you uploaded to PV, I can look at adding an export feature for that in future or similar.

Re: LearnIR with Pulseview

Thanks for the clarification I had hoped you'd just be able to copy the timing in in some way and get the image. PV does support it, but its non trivial. FYI: These logic Analyzers that work with PV can be bought from China for less than $10 delivered. So the easiest approach might be to get one and...

Re: LearnIR with Pulseview

1st Problem: PV does not support B&O , so you will not get a 'nice' image So I don't see why you would try any further. I played around with exporting from PV & had limited success. Try setting the demo device with 1M Samples at 1MHZ press the run button. Then save the session to one of the supporte...

Re: LearnIR with Pulseview

PV operates on state changes based on elapsed time from trigger. Your best shot would the channel 1/2 tables i AnalysIR. You can copy these values to the clipboard via the menu (or CTRL+1 or CTRL+2) This contains the time offsets and the state. In PV - save a session to CSV and review the format. Th...
