Example

--Note: due to the use of sys.wait() all apis need to be used in the coroutine
-- Usage Examples
local bh1750 = require "bh1750"
i2cid = 0
i2c_speed = i2c.FAST
sys.taskInit(function()
    i2c.setup(i2cid,i2c_speed)
    bh1750.init(i2cid)--initialization, passing in i2c_id
    while 1 do
        local bh1750_data = bh1750.read_light()
        log.info("bh1750_read_light", bh1750_data)
        sys.wait(1000)
    end
end)
