How did the kettle remote read
It has long been about to connect an IR receiver (1838B) and an IR transmitter (IR diode 5 mm, 940 nm, the radiation angle is about 80 degrees) to the Raspberry, to understand how they will work and what can be done with them. And once this day has come.
Having studied the problematics, including materials from Habr , I realized that in addition to the IR diode and the IR receiver, I also needed a transistor and several resistors, a little depressed. It is easier with the receiver - it came with a kit, but there was not enough transistor for the diode, but nevertheless decided to try it, what if it happens? And it turned out ...
Basically, I found all the necessary information in the open spaces, but in each material some time was missed, and something had to be thought through by myself. The situation was particularly complicated by the fact that I was programming a teapot, so some moments were not easy, so I will try for people like me to describe everything step by step and in as much detail as possible.
So, the IR receiver module is connected to GPIO23, gnd and 3.3V - the corresponding designations are on it. Between GPIO and 3.3V - resistor 10 com. The LED is through a 1 kΩ resistor to GPIO22 (anode) and gnd (cathode).
')
Next - install LIRC :
Editing the / etc / modules file:
Add to the file line:
Where:
gpio_in_pin = 23 - pin to which the receiver is connected.
gpio_out_pin = 22 - pin for transmitter.
Edit the file /etc/lirc/hardware.conf:
It should turn out like this:
Edit the file / boot / config.txt:
Add a line to the file:
Where:
gpio_in_pin = 23 - pin to which the receiver is connected.
gpio_out_pin = 22 - pin for transmitter.
Reboot raspberries:
Stop the lirc daemon:
We check the receiver operation with the command:
Now take any remote and press the buttons, directing to the receiver. Must run over the screen numbers.
Now the most interesting thing is to write down the configuration of your console (or several), so that the program compares the IR signal from the console with the name of the button and later can use this signal.
To do this, use the irrecord program that comes with lirc.
Where aa59-00741a is a model of my console, you can use any other name. In this example, the configuration file is saved in the home folder.
After starting, follow the prompts on the screen (in English).
When entering the names of buttons, it is better to use a list that is wired into the program.
The configuration file will be obtained - in our case with the name aa59-00741a.conf, it will be saved in the home folder. In the resulting file, I added via # comments to understand what the button is.
This action must be done for each console. The configuration file contains an important field - name. This is the name of the device by which lirc will determine which file to take the command from (in my case, Samsung_TV).
The resulting file is copied somewhere. I put it in the / etc / lirc / rc folder and added the line to the /etc/lirc/lircd.conf file:
Thus, the lirc configuration file will take information about my console from the aa59-00741a.conf file located in the / etc / lirc / rc folder. In my opinion, this is the easiest way to add information about the configuration of the console in the program settings.
Restart lirc:
Now, lirc can use the console data to transmit using the transmitter, or to recognize commands from the console and launch some action in response to the raspberry.
To do this, we place the transmitter as close as possible to the device (for testing, then we can empirically determine how far it will work) and write a command in the terminal, for example:
where irsend is the program for controlling the transmitter;
SEND_ONCE - one-time signal sending attribute;
Samsung_TV - device name from the configuration file (in the name field);
KEY_POWER - the name of the command from the configuration file to be sent.
Thus, the TV can turn on or off. With this command, I turn on or off the TV.
In the terminal, enter the command:
After that, when you press the buttons on the remote control, their names will be displayed from the configuration file.
The next step is to control the transmitter through the browser, but I have not yet studied this.
Will be happy to comment.

Next - install LIRC :
sudo apt-get install lirc Editing the / etc / modules file:
sudo nano /etc/modules Add to the file line:
lirc_dev lirc_rpi gpio_in_pin=23 gpio_out_pin=22 Where:
gpio_in_pin = 23 - pin to which the receiver is connected.
gpio_out_pin = 22 - pin for transmitter.
Edit the file /etc/lirc/hardware.conf:
sudo nano /etc/lirc/hardware.conf It should turn out like this:

Reboot raspberries:
sudo reboot Settings are complete and you can now check how everything works
Checking the IR receiver
Stop the lirc daemon:
sudo /etc/init.d/lirc stop We check the receiver operation with the command:
mode2 -d /dev/lirc0 Now take any remote and press the buttons, directing to the receiver. Must run over the screen numbers.
Must be something like this

Now the most interesting thing is to write down the configuration of your console (or several), so that the program compares the IR signal from the console with the name of the button and later can use this signal.
To do this, use the irrecord program that comes with lirc.
irrecord -d /dev/lirc0 ~/aa59-00741a.conf Where aa59-00741a is a model of my console, you can use any other name. In this example, the configuration file is saved in the home folder.
After starting, follow the prompts on the screen (in English).
Brief instruction in Russian
1) Launched
2) Enter
3) They took the remote in hand
4) Enter
5) Press different buttons on the remote until the program prompts you to enter the name of the button. In addition, each press should result in a point, but not more than 10 points per press
6) Enter the name of the pressed button
7) Press the button
8) And so on, until the buttons run out
9) Then Enter

This action must be done for each console. The configuration file contains an important field - name. This is the name of the device by which lirc will determine which file to take the command from (in my case, Samsung_TV).
The resulting file is copied somewhere. I put it in the / etc / lirc / rc folder and added the line to the /etc/lirc/lircd.conf file:
include "/etc/lirc/rc/aa59-00741a.conf" Thus, the lirc configuration file will take information about my console from the aa59-00741a.conf file located in the / etc / lirc / rc folder. In my opinion, this is the easiest way to add information about the configuration of the console in the program settings.
Restart lirc:
sudo /etc/init.d/lirc restart Now, lirc can use the console data to transmit using the transmitter, or to recognize commands from the console and launch some action in response to the raspberry.
We check the work of lirc and IR transmitter
To do this, we place the transmitter as close as possible to the device (for testing, then we can empirically determine how far it will work) and write a command in the terminal, for example:
irsend SEND_ONCE Samsung_TV KEY_POWER where irsend is the program for controlling the transmitter;
SEND_ONCE - one-time signal sending attribute;
Samsung_TV - device name from the configuration file (in the name field);
KEY_POWER - the name of the command from the configuration file to be sent.
Thus, the TV can turn on or off. With this command, I turn on or off the TV.
Another check of the IR receiver, as well as the correct perception of the configuration file by lirc
In the terminal, enter the command:
irw After that, when you press the buttons on the remote control, their names will be displayed from the configuration file.
The next step is to control the transmitter through the browser, but I have not yet studied this.
Will be happy to comment.
