Raspberry Pi - SPI Communication

Given this Python code snippet using spidev on Raspberry Pi:

import spidev
spi = spidev.SpiDev()
spi.open(0, 0)
spi.max_speed_hz = 1000000
response = spi.xfer2([0xAA, 0xBB])
print(response)

What will be the output format of the print statement?

AAn error because xfer2 returns None

BA string showing hexadecimal values

CA single integer representing combined bytes

DA list of integers representing received bytes

Step-by-Step Solution

Solution:

Step 1: Understand spidev xfer2 method
xfer2 sends a list of bytes and returns a list of bytes received from the SPI device.
Step 2: Analyze the print output
Printing the response will show a list of integers representing each received byte.
Final Answer:
A list of integers representing received bytes -> Option D
Quick Check:
spidev.xfer2 output = C [OK]

Quick Trick: xfer2 returns list of received bytes [OK]
