Remote GPIO access library
Project description
HTPIO : Remote I/O Access Library
HTPIO allows users to use Raspberry Pi's GPIOs or similiar hardware remotely using various telecommunication protocols. The library also offers a simple locking mechanism in order to implement advanced testing scenarios using shared hardware.
HTPIO is a subset of the Hilscher Test Framework for products of the netX family. A brief overview of some netX products is given in the links below:
- Network Controllers
- PC Cards
- Embedded Modules
- Gateways
- Industrial Internet / IoT
- Analysis and Data Acquisition
- Automation and Visualization
- Software
Requirements
- Python >=2.7
- Python >=3.4
Features
- Remote GPIO access using various protocols
- Pin locking to ensure shared use of hardware resources
- Command line interface for shell scripting
Installation
To install latest stable release from PyPi use pipenv (or pip):
pipenv install htpio
or install the latest stable version from BitBucket:
pipenv install https://bitbucket.org/hilscherdtc/htpio/get/stable.tar.gz
Library interface
>>> from htpio import bridge, socketio, telnetio
>>> device = telnetio.RaspberryPi('192.168.199.31')
>>> gpio = bridge.RemoteAccess(device)
>>> gpio.lock(14)
>>> gpio.unlock(14)
>>> gpio.islocked(14)
>>> gpio.configure(14, gpio.OUTPUT)
>>> gpio.set(14, 1)
>>> gpio.get(14)
>>> gpio.deconfigure(14)
>>> gpio.logout()
Command line interface
$ htpio -p telnet set --host 192.168.199.31 --pin 14 --val 1
$ htpio -p socket get --host 192.168.199.31 --pin 14
$ htpio lock --host 192.168.199.31 --pin 14
$ htpio unlock --host 192.168.199.31 --pin 14
