grove.py

Python library for Seeedstudio Grove Devices on embeded Linux platform, especially good on below platforms:

• Coral Dev Board (Wiki)
• NVIDIA Jetson Nano (Wiki)
• Raspberry Pi (Wiki)

Architecture

To operate grove sensors, the grove.py depends on the smbus2 hardware interface library.

Installation

For beginner or library user only, please install with online method.
For developer or advanced user, please install dependencies and then install grove.py with source code.

Caution

Here is the compatibility of grove.py with Python2 and Python3 on each releases of Raspbian/Raspberry Pi OS.

Because Python2 is obsolete and APT repository does not provide python-pip, so the Raspberry Pi OS releases which after 10 (Buster) 2020-08-20 cannot use Online install command. We also recommend using Python3 to all the users and developers.

Online install

install/update all dependencies and latest grove.py

curl -sL https://github.com/Seeed-Studio/grove.py/raw/master/install.sh | sudo bash -s -

Install grove.py

From source code

git clone https://github.com/Seeed-Studio/grove.py
cd grove.py
# Python2 (This command line does not provide for Raspberrypi OS 10 (Buster) >= 2020-12-02)
sudo pip install .
# Python3 
sudo pip3 install .

Usage

Basic GPIO Input & Output demo

import time
from grove.gpio import GPIO

led = GPIO(12, GPIO.OUT)
button = GPIO(22, GPIO.IN)

while True:
    if button.read():
        led.write(1)
    else:
        led.write(0)
    time.sleep(0.1)
