Sep 18, 2017 · In that case, the python was in a local virtualenv and pip wasn't, so python -m pip install would install in the local virtualenv, whereas pip would try to install in the system python (and fail w/o sudo). Share, sync, and collaborate on files securely with Dropbox Business, a file sharing and cloud storage solution that employees love and IT admins trust. ) We'll use a special library called adafruit_blinka (named after Blinka, the CircuitPython mascot) to provide the layer that translates the CircuitPython hardware API to whatever library the Linux board provides. For boards with labeled SCL and SDA pins, you can:. This section contains documentation with technical information about the Raspberry Pi hardware, including official add-ons and the Pi itself. The way to create an I2C object depends on the board you are using. Members of the Mu community were also speaking at EuroPython. SDA) sensor = adafruit_lsm303. The following section will show how to control the IS31FL3731 from the board's Python prompt / REPL. Ports must imple-ment the C API to support the corresponding module. Sphinx documentation¶ Sphinx is used to build the documentation based on rST files and comments in the code. SDA frequency = 100000) Since we have the I2C bus object, we can now use it to instantiate the SGP30 object:. You can use this sensor with any CircuitPython microcontroller board or with a computer that has GPIO and Python thanks to Adafruit_Blinka, our CircuitPython-for-Python compatibility library. import time import busio import board import adafruit_focaltouch # Create library object using our Bus I2C port i2c = busio.
