The installer has installed everything correctly. It is so specifically conceived that when entering on 192.168.3.1, Onion OS was opened because Onion console is not installed in new Omega2 during installation. To fix this, you may need to edit the file /www/index.html
Hey. An update was recently released in which Onion added support for all Python2 modules for Python3: https://onion.io/2bt-python3-modules/
Try to enter
opkg install python3-onioni2c
Hey. I am very glad that this event happened! I hope that developers will more often tell us such wonderful news!
Is the pinout diagram from Оmega-2 suitable for Omega-2 +?
Can I use pins 6, 7, 8, 9 as GPIO?
Is there an Onion Gpio library for Python 3?
Thanks in advance for answers

ls /dev/gpio*
ls: /dev/gpio*: No such file or directory
I installed the module python-periphery to use the GPIO, but there is a problem when calling.
>>> from periphery import GPIO
>>> GPIO("/dev/gpiochip0", 11, "out")
Traceback (most recent call last):
File "/usr/lib/python3.6/site-packages/periphery/gpio.py", line 355, in _open
self._chip_fd = os.open(path, 0)
FileNotFoundError: [Errno 2] No such file or directory: '/dev/gpiochip0'
During handling of the above exception, another exception occurred:

Many thanks. I like python, but it, like other languages, has its drawbacks.
Python 3.6.0 (default, Mar 27 2018, 01:18:40)
[GCC 5.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import AdcExp
>>> adc_1 = AdcExp.AdcExp(address=0x48)
>>> accel_volt_x = adc_1.read_voltage(0)
>>> g_x = (accel_volt_x - 1.51) / 0.35
>>> g_x
0.34267857142857155
>>> round(g_x, 1)
0.29999999999999999
I want to round the number to tenths, but 'round' does not work correctly.
Tell me, are there any ready-made libraries for reading angular velocities or angle of rotation relative to the axes from a digital gyroscope-accelerometer (mpu-9250 or the like) using Python3 and Omega2?

This method works. Thank you!
