Microcontrollers with Gleam
summary
Framework for running Gleam on tiny devices using AtomVM with working prototypes on ESP32 and Raspberry Pico, showing actor-based concurrency, GPIO and I2C peripheral drivers, and a blinky plus joystick+display demo that mostly works but shows display latency. Describes using Gleam tooling, a custom inc framework, rebar3/ex_unit plugins and the inep flash workflow, tradeoffs versus Rust/C/C++ and MicroPython, and concrete limitations discovered in the AtomVM BEAM subset.
