Python 3 gpiod module error

pochin2208 · October 15, 2020

Hi, I've been trying to get the next IMU sensor to work: Fusion_IMU_BNO055, on my OPi zero with Armbian Bionic 20.08.10 with the linux kernel 5.8.14-sunxi. I have installed everything from the official Adafruit guide but I still get the same error.

I have followed all the steps of this guide for beginners: OPi_r1_guide, executing all the commands successfully. However, I still have the same error in Python that is related to the "board" module.

>>> import board
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    from adafruit_blinka.board.orangepi.orangepizero import *

    PA0 = Pin(0)
  File "/usr/local/lib/python3.6/dist-packages/adafruit_blinka/microcontroller/generic_linux/libgpiod_pin.py", line 34, in __init__
    self._chip = gpiod.Chip("gpiochip0", gpiod.Chip.OPEN_BY_NAME)
AttributeError: module 'gpiod' has no attribute 'Chip'
>>> exit()

The python code that I try to execute is the following:

import board
import digitalio
import busio

print("Hello blinka!")

# Try to great a Digital input
pin = digitalio.DigitalInOut(board.PA6)
print("Digital IO ok!")

# Try to create an I2C device
i2c = busio.I2C(board.SCL, board.SDA)
print("I2C ok!")

# Try to create an SPI device
spi = busio.SPI(board.SCLK, board.MOSI, board.MISO)
print("SPI ok!")

print("done!")

If you need more details I will gladly give them to you. Thank you.
