3.3.3 The Business Case: Advantages and Challenges

  • Strengths: True MCU optimization, a permissive MIT license with unrestricted commercial use, an active community, and LVGL Pro for visual design.
  • Challenges: Manual C UI code is slower and more error-prone than declarative approaches. Pure C lacks the memory-safety guarantees of Rust, placing the burden of correct allocation and pointer handling on developers. The imperative API becomes hard to maintain as state complexity grows.
