PicoOS

A lightweight graphical operating-system experiment for the Raspberry Pi Pico, using LVGL and an SPI TFT display.

A small graphical operating-system experiment targeting the Raspberry Pi Pico, an SPI TFT display and the LVGL graphics library. Iteration continues against an RP2040 bring-up baseline.

01Project brief

Scope and current stage.

This page reports the documented state of the work. It does not represent qualification, manufacturing release, or operational deployment unless stated explicitly.

Objective: Explore a small embedded GUI stack with RP2040 hardware integration, display bring-up and serial debugging.
Development stage: Embedded prototype - iteration ongoing
Technology areas: RP2040LVGLCMake
Publication note: Further specifications are withheld until they are supported by the current engineering record.

02Notes

Background

PicoOS explores the boundary between an MCU-friendly kernel and a small graphical user interface. The Pico is small enough to make every cycle and every byte count, which makes it a useful target for understanding what an embedded GUI stack can and cannot do without an MMU.

The goal is a working prototype with a documented bring-up sequence and a serial-debug interface, not a production RTOS.
