Problem with lcd 1602 #9

Open liyuanyuan-rudel opened 3 years ago

30_i2c_lcd1602.py

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?
