A retro-style, ASCII micro–operating environment for the M5Stack Cardputer, inspired by early home computers such as the ZX Spectrum, Commodore 64 and Amstrad CPC — and based conceptually on the original tinyComputer project (written in Godot).

tinyCardputer brings the spirit of 80s programming to a real handheld device, allowing you to write programs, run commands, and interact with a tiny scripting language directly on the Cardputer itself. No PC required — the Cardputer becomes the computer.

tinyCardputer is a minimalistic retro environment that includes:

• A green ASCII terminal with simulated vintage style.
• A built-in tiny scripting language, inspired by tinyComputer's MiniCoder.
• On-device programming through the miniCoder editor, with line numbers and live execution.
• System commands such as:
  • echo — print text
  • beep — beeper sound with variable pitch
  • window — ASCII message windows
  • wait — timed delays
  • boot — boot sequence sound
  • error — error tone
  • clear, help, exit
• A splash screen embedded in ROM.
• Sequential script execution with delays (like coroutines).
• A working beeper engine.
• 100% offline, self-contained retro micro-OS feel.

The goal is to recreate the experience of learning to code as in the old days: typing simple commands, experimenting, and seeing immediate results — just like programming a ZX Spectrum or Commodore 64, but on a modern Cardputer.

tinyCardputer is a derivative project of tinyComputer, originally developed in Godot 3.5 as a virtual retro computer intended for beginners and experimentation.

tinyCardputer takes that conceptual foundation and ports it to an actual hardware device — the M5Stack Cardputer.

Where tinyComputer was virtual, tinyCardputer is real.
