Replacing IR Reciver with IR Transmitter

rufik

Quick question - can ir reciver (LBST0038A) be easily replaced by any ir transmitter? I'd like to make my OPI 2 a remote conroller for AC.

You can drive IR transmitter via GPIO. You need a driver, which is not a part of the kernel. Next problem is encrypted protocol ... Check this website for all about IR hacks: https://www.analysir.com/blog/

In Arduino world it is much easier. There are very good IR libraries and example programs where you can read IR remote codes and than use them in your program sending them via IR LED to the device. Probably you could adapt it here without pure Linux way via kernel module, just using bitbanging of GPIO pin.

@cbm80 Thanks for info. I'll will take a look into arduino also.

Hi, I'm also interested in this question.

I've installed bunch of stuff to enable gpio and lirc, mostly followed
http://www.instructables.com/id/ ... ng-up-the-Software/

And finally stuck on enabling module lirc_rpi, original command is

1. lirc_rpi gpio_in_pin=23 gpio_out_pin=22

Copy code

but what can We use in orange pi, is there any thing ?

There seems to be a fork of  lirc_rpi called lirc-gpioblaster
https://wiki.openwrt.org/doc/howto/lirc-gpioblaster
but it's for OpenWRT

AFAIK ir reciver is connected to PL11 pin, according to fex file:

1. [s_cir0]
   
2. ir_used = 1
   
3. ir_rx = port:PL11<2><1><default><default>
   
4. ir_power_key_code0 = 87
   
5. ir_addr_code0 = 40704
   
6. ir_power_key_code1 = 26
   
7. ir_addr_code1 = 64260
   
8. ir_power_key_code2 = 20
   
9. ir_addr_code2 = 32640
   
10. ir_power_key_code3 = 21
    
11. ir_addr_code3 = 32640
    
12. ir_power_key_code4 = 11
    
13. ir_addr_code4 = 63240
    
14. ir_power_key_code5 = 3
    
15. ir_addr_code5 = 239
    
16. ir_power_key_code6 = 159
    
17. ir_addr_code6 = 19635
    
18. ir_power_key_code7 = 10
    
19. ir_addr_code7 = 30536
    
20. ir_power_key_code8 = 69
    
21. ir_addr_code8 = 48386
    
22. ir_power_key_code9 = 77
    
23. ir_addr_code9 = 56865
    
24. ir_power_key_code10 = 24
    
25. ir_addr_code10 = 65025
    
26. ir_power_key_code11 = 87
    
27. ir_addr_code11 = 65280
    
28. ir_power_key_code12 = 77
    
29. ir_addr_code12 = 65344

You created some decent points there. I looked on the internet for any issue and found most people should go as well as with the internet site.        Mẹo chơi thể thao ảo VIN777

An intriguing discussion might be priced at comment. I do believe you should write much more about this topic, it will not be considered a taboo subject but usually people are there are not enough to talk on such topics. To the next. Cheers        Packers and Movers Gurgaon to Port Blair

An intriguing discussion will probably be worth comment. I do believe that you can write regarding this topic, may possibly not often be a taboo subject but generally individuals are inadequate to communicate on such topics. Yet another. Cheers        https://bk8v3.com/
