Adafruit has this week announced the availability of its fourth beta release for the current CircuitPython 6.2.0 development phase, making it available to download and test. The new release adds a second USB serial (CDC) channel across most ports, adds a bitmaptool module for help with displayio, and removes the limitation on displayio.Group size. Adafruit explains that the “RP2040 port has many enhancements and fixes, and the Spresense port has several improvements as well. See Port status below for details on port stability for each port, and Known issues for known problems”.
CircuitPython is a programming language designed to simplify experimenting and learning to code on low-cost microcontroller boards. With CircuitPython, there are no upfront desktop downloads needed. Once you get your board set up, open any text editor, and start editing code. It’s that simple. With CircuitPython, there are no upfront desktop downloads needed.
