grove.py 0.2

Python library for Seeedstudio Grove devices

grove.py

Python library for Seeedstudio Grove Devices on Raspberry Pi.

Installation

sudo pip install grove.py

Usage

After installing grove.py, A few CLI commands with prefix grove_ is available, such as grove_led, grove_button, grove_ultrasonic_ranger and etc. For I2C Grove devices, the default bus is used (I2C 1 on Pi). For digital input & output Grove devices, pin numbers should be provided as the arguments of these commands.

grove_i2c_color_sensor_v2
grove_led 12
grove_button 22
grove_ultrasonic_sensor 12 13

For digital output device like Grove - LED

import time
from grove.grove_led import GroveLed

led = GroveLed(12)

while True:
    led.on()
    time.sleep(1)
    led.off()
    time.sleep(1)

For digital input device like Grove - Button

import time
from grove.grove_button import GroveButton

button = GroveButton(12)

def on_press(t):
    print('Button is pressed')

button.on_press = on_press

while True:
    time.sleep(1)

Basic GPIO Input & Output

import time
from grove.gpio import GPIO

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

def on_button_event(pin, value):
    print('pin {} is {}'.format(pin, value))
    led.write(value)

button.on_event = on_button_event

while True:
    time.sleep(1)

For Grove 4 Digit Display

import time
from grove.grove_4_digit_display import Grove4DigitDisplay

display = Grove4DigitDisplay(12, 13))

count = 0
while True:
    t = time.strftime("%H%M", time.localtime(time.time()))
    display.show(t)
    display.set_colon(count & 1)
    count += 1
    time.sleep(1)

For Grove I2C Color Sensor V2

import time
from grove.grove_i2c_color_sensor_v2 import GroveI2CColorSensorV2
sensor = GroveI2cColorSensorV2()

print('Raw data of red-filtered, green-filtered, blue-filtered and unfiltered photodiodes')
while True:
    # r, g, b = sensor.rgb
    r, g, b, clear = sensor.raw
    print((r, g, b, clear))
    time.sleep(1.0)
