I would like limited multicore access to the second core from circuitpython on the RP2040. It’s okay if that access is just to C/C++ code running on the second core with Circuitpython running on the first core. I’d like some means to pass variables back and forth. Could be a mailbox, queue, shared memory, or whatever is currently supported by the RP2040’s C API. The communication does not need to be real-time, 1ms would be fast enough for me, though real-time locks as supported by Micropython would be great. #CircuitPython2022
I think it would be a good idea to generalize the event system used by the keypad library so it and other core modules would be able to deliver events in a common queue. Events would be objects of a specific class for the event type deriving from an Event base class in the same way that specific exceptions derive from Exception.
#CircuitPython2022 is our annual reflection on the state of CircuitPython. We’d love to hear from you too! See the kick-off post for all of the details. Here are the previous posts:
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
