Info

Python script to control GPIO over TCP TCP server can run on RaspberryPi. Server side uses gpio command, client adds argument -g to the pin number

Requierements

Python 3

Requierements for raspberry-pi

RaspberryPi with socat and user permissions for /dev/gpio sudo apt-get install wiringpi, socat

Client Installation

pip install -e .

RaspberryPi configuration

Copy folder gpio_server to your bin folder, or add it in PATH Add to your /etc/rc.local code to run gpio_server/start_server.sh

Usage

>python -m gpio_over_tcp --help
usage: __main__.py [-h] [--host HOST] [--port PORT]
                   [-v {debug,info,warn,error,fatal}]
                   {set,reset,toggle,status,out,in} pin [pin ...]

GPIO control over TCP

positional arguments:
  {set,reset,toggle,status,out,in}
                        'out', 'in' - set pin mode: output or input;
                        'set','reset','toggle' to set desired value on the pin
                        'status' to read current status of the pins
  pin                   pin number(s) to control (can be a list, separated by space)

optional arguments:
  -h, --help            show this help message and exit
  --host HOST           host name or IP address, 
                        env_var "GPIO_HOST:host;port" is used for default
  --port PORT           TCP port for connection
  -v {debug,info,warn,error,fatal}, --verbose {debug,info,warn,error,fatal}
                        logger level, default: error

You can create envirenment variable GPIO_HOST with value host address;port e.g.: export GPIO_HOST="localhost;5001", in that case you don't need to specify arguments --host and --port

Examples

> python -m gpio_over_tcp status 16 12
pin_16(16): OUT | High
pin_12(12): OUT | High

>python -m gpio_over_tcp toggle 16 12

>python -m gpio_over_tcp status 16 12
pin_16(16): OUT | Low
pin_12(12): OUT | Low
