You can use this I/O expander with any CircuitPython microcontroller board or with a computer that has GPIO and Python thanks to Adafruit_Blinka, our CircuitPython-for-Python compatibility library. Installing the SMBus: As it came out from the above discussion the first step in I2C communication between the Raspberry Pi and I2C device via I2C communication bus through the Python language is to install the SMBus. Starting with v0.2, the smbus2 library also has support for combined read and write transactions. The Sense HAT features an 8x8 RGB LED matrix, a mini joystick and the following sensors: Gyroscope However, there's smbus2 library which solves that problem by providing an interface to make things like write-word-then-read-block more easy. Installation pip3 install lis3dh Usage. So, the picamera package for Python 2.x is named python-picamera (as shown in the example above). This BME680 software was tested on Linux Debian using Python 2.7 with python-smbus2 module loaded. Meta. It should be a drop-in replacement of smbus.
