Miyoo Mini Plus Input Engine

This project implements a high-speed text input system designed for the Miyoo Mini Plus (ARMv7, Linux/Onion OS). It features a "Linear QWERTY Ribbon" and a vertical "Prediction Crank" with smooth elastic physics.

Features

• Linear QWERTY Ribbon: Horizontal character selection with smooth scrolling.
• Prediction Crank: Vertical word suggestion list on the right.
• Physics: Linear Interpolation (VisualPos += (TargetPos - VisualPos) * 0.22f) for premium feel.
• Snap-and-Bounce: Automatic alignment to center selection.
• Controls:
  • D-pad L/R: Spin Ribbon.
  • L1/R1: Jump 5 characters.
  • SELECT: Toggle focus between Ribbon and Crank.
  • START: Auto-complete word/character.
  • D-pad U/D: Scroll Prediction Crank (when focused).

Dependencies

• SDL2
• SDL2_ttf
• C++17 compliant compiler

Build Instructions

macOS / Linux (Desktop Testing)

You can use CMake or the provided Makefile.

Using CMake:

mkdir build
cd build
cmake ..
make
./MiyooInputEngine

Using Makefile:

make
./MiyooInputEngine

Cross-Compilation for Miyoo Mini Plus

To compile for the Miyoo Mini Plus, you need the appropriate toolchain (usually arm-linux-gnueabihf).

Example Makefile adjustment:

CXX = arm-linux-gnueabihf-g++

Ensure SDL2 and SDL2_ttf libraries for the ARM target are available in your toolchain search path.

Assets

Place a valid TrueType font at assets/fonts/default.ttf. The system attempts to load this file first.
