rpinserver

Ultra simple webserver for accessing Raspberry Pi GPIO pins. It's not extra neat. It could have been done better. It could avoid using html tables. But hey, it's just a simple tool written in one evening.

Installation

If you want to start this server autmatically on your rpi boot, put following line in /etc/rc.local:

su - pi -c "screen -dm -S rpinserver sudo python3 /home/pi/rpinserver/server.py"

(assuming you've cloned this project in /home/pi). After starting it turns sequentionally every output for 0.1s so user can see it has booted.

Configuration

Pins to controll are defined at the beginning of the fie:

PINS = [25, 8, 7, 1, 6, 13, 19, 26]

Adjust this array to suit your needs. Pins are indexed by indexes in this array - at index 0 is GPIO25, at index 1 is GPIO8 etc. All pins are set as output pins.

Usage

Web UI

Just navigte to http://your-pi. You should see ugly '90s style html table representing state of the pins with buttons to change them:

API

Getting state of pin

Address (GET):

/[index]

Output:

• 0 for turned off
• 1 for turned on

Example:

# get state of first gpio
someone@somewhere:~ $ curl your-pi/0
1

Setting state of pin

Address (POST):

/<index>

Data:

state=<value>, where <value> is 0 or 1.

Example:

# turn on second gpio
someone@somewhere:~ $ curl -d state=1 your-pi/1

Setting state of multiple pins

Address (POST):

/

Data:

<index>=<value>[&<index>=<value>]*, where <value> is 0 or 1.

Example:

# turn on first and third gpio, turn off fourth gpio, don't change other gpios
someone@somewhere:~ $ curl -d "0=1&2=1&3=0" your-pi
