For I2C, it manages the device address. The SPI hardware module is used much better in the Adafruit library so execution speed is faster in all cases comparing hardware SPI modes. I've looked through the library files (found here) and I see that the read and write functions use arrays of 8-bit values, but I can't tell if it automagically breaks the 32-bit value apart and then puts it back together when read, or if it's just writing & reading a series of separate 8-bit values. The notable libraries are urllib, adafruit_epd, weather_graphics. examples/ssd1331_simpletest.py ... the display using displayio and draw a solid red background """ import board import displayio from adafruit_ssd1331 import SSD1331 spi = board.
