Glowtape is a unique DIY wristwatch by Henner Zeller that uses glow-in-the-dark tape and an RP2040 microcontroller to display the time.
Pete Warden shares his experience and knowledge about the memory layout of the Raspberry Pi Pico board, specifically the RP2040 microcontroller. He encountered baffling bugs while updating TensorFlow Lite Micro and traced them to poor understanding of the memory layout. The article provides detailed insights into the physical and RAM layouts, stack behavior, and potential pitfalls.

Matt Evans developed the project over an undisclosed amount of time. He was inspired by a conversation about building a desktop GUI for the Raspberry Pi Pico’s RP2040 MCU. Evans’s goal was to bring the Macintosh 128K to life to run the originally bundled software and the all-important Missile Command.
