Your logic analyzer shows a clean clock, your SPI flash returns 0xFF on every read, and you have no idea whether the bug lives in your code or on the wire. James Bowman of Excamera Labs wants to end t
Special-purpose hardware built to reject wrong answers fast, before handing the few survivors to a slower, smarter processor, is a pattern that goes back a century and still shows up in Bitcoin ASICs,
Grab whatever RP2350 board is sitting in your parts drawer — Adafruit shipped CircuitPython 11.0.0-alpha.1 on September 24, and it's a solid weekend flash if you've been putting off the jump from the
To try this at home you need a Raspberry Pi Pico 2 or any other RP2350 board, a DVI breakout (or a hand-wired resistor ladder across four differential GPIO pairs), a short HDMI cable, and a monitor th
