A MicroPython library for interfacing with the TSL2561 light sensor.
It's a fork of the depreciate lib : https://github.com/adafruit/micropython-adafruit-tsl2561
Works fine with Raspbery pi pico and micropython. Tested with : sysname='rp2' nodename='rp2' release='1.19.1' version='v1.19.1-910-g4937174b4 on 2023-03-01 (GNU 12.1.0 MinSizeRel)' machine='Raspberry Pi Pico with RP2040'
from machine import Pin, I2C
from tsl2561 import TSL2561
i2c=I2C(0,sda=Pin(4),scl=Pin(5), freq=100000) # 100 kHz!!!
sensor = TSL2561(i2c) #default addr is 0x39 = 57
lum = sensor.read()
print(f"Luminosity : {lum} lux")
