So you have a new board, that you want to get working with Blinka, our CircuitPython library compatibility layer for Single Board Computers, or SBCs. Adding a board to Blinka is a 2-part process with the first step being to add it to PlatformDetect so that Blinka knows what board it is working with.
The way that Blinka works is it combines multiple techniques to access the parts of the board that it needs. For GPIO, libraries such as RPi.GPIO or libgpiod are used. For I2C, the PureIO python library is used, and for SPI, we are using the spidev python library.
When it comes to Blinka itself, there are two main components that need to be defined…
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
