LCD1602.init(0x27, 1) # init(slave address, background light)
Until this line, all things are fine, because when I change it to LCD1602.init(0x27, 0) background light is closed.
So I think the address and connection is right.
but the characters are not showing on the screen.
Could you please check it？
