lefuturiste / bmi160-i2c

WIP lib to communicate with the BMI160 accel/gyro sensor with the raspberry pi i2c in python

Hi, I'm lefuturiste 👋

I'm a french 🇫🇷 developer who likes to build websites 🌐 and robots 🤖.

I use plenty and various technologies but I code mainly in Rust, Python, PHP and JS. 💻

Currently I'm trying to get away from github and use other software forges services, like the one that are based on Forgejo. You can find me on my personal forge instance: https://forge.lefuturiste.fr/.

Some of my side-projects are :

• 🎮 RetroBox, the open source console on github with Thingmill
• 🚀 WikiArchives.space a website to archive spaceflight photos also on github.

In 2020 I worked on a robot for the French robotic cup with my team We Robot.

I like to spend some of my time on open source projects like Jobatator a project in Go or Vue-Apitator a plugin for Vue.js.

I also to contribute to some Open Data projects like OpenStreetMap or WikiData

The best way to reach me is either by Mastodon or by email.

bmi160-i2c's Issues

Can't change bus

self.i2cbus = Driver(addr=0x68, bus=10)
TypeError: __init__() got an unexpected keyword argument 'bus'

Cant change the bus to 10 on init of Driver

Works on Jetson Nano

Successfully tested example "all.py" on Jetson Nano with BMI160. Works well.

BMI160 connected as per the NVIDIA Isaac SDK Jetson to BMI160 wiring tutorial. https://docs.nvidia.com/isaac/isaac/doc/tutorials/wire_bmi160_imu.html

Stuck at "Trying to initialize the sensor..."

I have it wired up properly and my i2c address is showing as 0x6A which I changed, but it is not getting past
sensor = Driver(0x6A)

Any advice on what is going on? Anything to inspect or see? I am trying this on a Raspberry Pi 4.

Thank you

Some registers are not in the definitiions file.

Hi,
I noticed that GYRO_OFFSET_EN, GYR_OFFSET_X_MSB_LEN, GYR_OFFSET_X_MSB_BIT ... are not in the definitions file. the same for gyro y and z. So it generates an error when you call the functions to get the offsets.

STEP_* definitions are missing

I think they should be something like:

STEP_BUF_MIN_BIT = (0)
STEP_BUF_MIN_LEN = (4)

Step counter definitions

STEP_MODE_NORMAL = (0)
STEP_MODE_SENSITIVE = (1)
STEP_MODE_ROBUST = (2)
STEP_MODE_UNKNOWN = (0)

mismatch in code between github and published python module

There seems to be a difference between the code that is available in github repo and the module that can be installed from https://pypi.org/project/BMI160-i2c/. Even though the version installed says 0.5 it seems to be missing several constants and the parameters to initialize sensor.

The workaround for me was to uninstall the module that was installed by pip and install it from code from this github repo like this:

pip uninstall bmi160-i2c
git clone https://github.com/lefuturiste/BMI160-i2c.git
cd BMI160-i2c
sudo python3 setup.py install

In addition, the all.py example will only work if the i2c addr is default addr. I have submitted a pull request to allow anyone to easily change it in all.py example as well.

Hope that helps someone.

sleep_us incorrect?

def sleep_us(duration):
return sleep(duration * 0.0001)

I guess there should be 0.000001, ie 10^-6
