As a very beginner of the Micropython, I'm playing with a Standard HD44780 LCDs mounted with Adafruit i2c/SPI LCD Backpack arduino-i2c-use connected to LoPy4 through the default I2C interface.
Unlike the multiple drivers showed over there (https://github.com/dhylands/python_lcd), I haven't seen any drivers specifically for the Pycom board. I suppose that one can simply modify the driver by using the given I2C address of the backpack. So I try the code below to retrieve the address of the Adafruit backpack, and I was returned nothing.
Code: Select all
>>> from machine import I2C
>>> i2c=I2C()
>>> i2c.scan()
[]
>>>
My question is most I2C slave address is 98, 63, etc. What does mean for "address of 0"?
Can anyone give any instruction? That will be greatly helpful for me! Thank you in advance.
