SPI is a fast and robust communication protocol that are commonly found on many microcontrollers and is often used to retrieve sensor data or output image signal to a display.
Then copy and paste the following code line by line into REPL to see their effects.
from machine import SPI spi = SPI(1) # Only support 2 sets of SPI -- 0 and 1, for connection please refer to the table below spi.write(bytes()) # Write number 123 spi.read(8)
