Decompiler — Uf2

While a UF2 decompiler pipeline can recover program logic, you will never get a perfect 1-to-1 replica of the original source code due to the nature of compilation:

With -O2 or -Os (size optimization), the compiler will: uf2 decompiler

Developed by the NSA, Ghidra is the most powerful free tool for this task. It supports almost every microcontroller architecture found in UF2 files (ARM Cortex-M, ESP32, etc.). Its "Decompiler" tab will attempt to reconstruct C code from the assembly. While a UF2 decompiler pipeline can recover program
