rc-switch-pi-examples

This repo contains examples showing you how to use rc-switch on a Raspberry Pi

rc-switch is a library to operate 433/315Mhz devices like power outlet sockets. It was first built for Arduino, but now works on Raspberry too.

This github repo shows some simple examples that are very much like the Arduino examples.

If you just want to run the examples without compiling, take a look inside the /bin folder.

Install Git

To clone the git repositories used in this project, install git:

sudo apt-get install git

Install WiringPI

To use rc-switch on the Pi, you need WiringPi

cd ~/
git clone git://git.drogon.net/wiringPi
cd wiringPi
./build

Get these examples

If you haven't downloaded these examples yet, you can clone them using

cd ~/
git clone https://github.com/SamDecrock/rc-switch-pi-examples.git
cd rc-switch-pi-examples

Get rc-switch

To run compile these examples, you need the rc-switch library.

From this folder, run

git clone https://github.com/sui77/rc-switch.git

Compile the examples

From this folder, run

make

This should leave you with the following executables:

senddemo
receivedemo
receivedemo_json

Running the examples

Make sure your receiver and sender are correctly connected:

sender connected to WiringPi Pin 0 (real pin 11).
receiver connected to WiringPi pin 2 (real pin 13).

See: https://pinout.xyz

senddemo

To run the send demo:

./senddemo

This examples sends a single message.

Sample output:

Starting senddemo
Make sure you have connected the 433Mhz sender data pin to WiringPi pin 0 (real pin 11). See: https://pinout.xyz/pinout/pin11_gpio17

Sending something
Done

receivedemo

To run the receive demo:

./receivedemo

This examples just listens for all incomming signals. If rc-switch can decode them, they will be shown here. The output is similar to the ReceiveDemo_Simple.ino from Arduino

Sample output:

Starting receivedemo
Make sure you have connected the 433Mhz receiver data pin to WiringPi pin 2 (real pin 13). See: https://pinout.xyz/pinout/pin13_gpio27

Listening
Received 10 / 24 bit Protocol: 2
Received 10 / 24 bit Protocol: 2
Received 10 / 24 bit Protocol: 2
Received 10 / 24 bit Protocol: 2
Received 10 / 24 bit Protocol: 2
Received 10 / 24 bit Protocol: 2

receivedemo_json

To run the receive demo (json):

./receivedemo_json

This example wraps every output in a JSON formatted message so you can easily use it in other projects.

Sample output:

{"status":"starting"}
{"status":"listening"}
{"value":74,"bitlength":24,"delay":706,"protocol":2}
{"value":74,"bitlength":24,"delay":706,"protocol":2}
{"value":74,"bitlength":24,"delay":706,"protocol":2}
{"value":74,"bitlength":24,"delay":706,"protocol":2}
{"value":74,"bitlength":24,"delay":706,"protocol":2}
