A MicroPython library designed to control the Grove LCD RGB Backlight V5.0 I2C display

Grove-LCD RGB Backlight v5.0 Library for MicroPython

This library is designed to control the Grove-LCD RGB Backlight V5.0 display using MicroPython.

Installation

• With mpremote

mpremote cp /path/to/rgb_lcd_v5.py :/lib/

Use

from rgb_lcd_v5 import Display

display = Display(sda=0, scl=1, i2c_bus=1, freq=400000)

Exemple

• Hello World

from rgb_lcd_v5 import Display

# Change sda and scl pin if needed
display = Display(sda=0, scl=1)
display.clear()

display.write("Hello World")

• Backlight Color

import time
from rgb_lcd_v5 import Display

display = Display(sda=0, scl=1, i2c_bus=1)
display.clear()
display.write("Red Color")
display.color(255, 0, 0)

• Backlight Color Blink

import time
from rgb_lcd_v5 import Display

display = Display(sda=0, scl=1, i2c_bus=1)

while 1:
    display.color(0, 0, 255) # Blue
    time.sleep(1)
    display.color(0, 255, 0) # Green
    time.sleep(1)

• Cursor Blink

import time
from rgb_lcd_v5 import Display

display = Display(sda=0, scl=1, i2c_bus=1)
display.clear()


while 1:
    display.blink(True)
    time.sleep(1)
    display.blink(False)

• Autoscroll

import time
from rgb_lcd_v5 import Display

display = Display(sda=0, scl=1)
display.clear()

while 1:
    display.setCursor(0, 0)

    # Write at begining of the first line
    for i in range(10):
        display.write(i)
        time.sleep_ms(300)

    display.setCursor(16, 1)
    display.autoscroll(True)

    # Write at the end of the second line
    for i in range(10):
        display.write(i)
        time.sleep_ms(300)

    display.autoscroll(False)
    display.clear()

Scan I2C Pins

• If you don't know what your I2C pins are

from rgb_lcd_v5 import scan_i2c_pins

scan_i2c_pins(i2c_bus=1)
