Deep Dive w/Scott: Merging and Blinking #adafruit
34Join Scott as he answers questions, discusses the end of the MicroPython merge and revisits the status LED revamp.
I’m sponsored by Adafruit to work on CircuitPython. Support them, and by extension me, by purchasing hardware from https://adafruit.com
Chat with me and lot of others on the Adafruit Discord at https://adafru.it/discord.
Deep Dive happens every week. Normally Fridays at 2pm Pacific but occasionally shifted to Thursday at 2pm. Typically goes for two hours or more. Questions are welcome. Next week is on Friday.
