📖 How to use Register Editor?

Register Editor is a quick and simple tool for visualizing and manipulating a single 32-bit word. It instantly shows which bits are set in a HEX value, without needing to open the Windows calculator in programmer mode.

1. Input Value (Reading from register)
  • If you read a value from a datasheet or debugger (e.g., GDB) 0x40021000, paste it directly into the top field.
  • The visualizer immediately splits it into 32 separate squares, showing set bits (blue with '1').
  • The field accepts formats: HEX (0x...), BIN (0b...), and decimal values.
2. Bitwise Operations (Editing)
  • You can modify the value simply by clicking the dark or highlighted squares on the memory map.
  • After each click, the Input Value (HEX) updates live!
  • This is very useful when you know, for example, that bit 14 and 17 must be set, but you don't remember offhand what HEX mask that produces.
3. Ready C Code & Conversions

The tool automatically generates a single-line bitmask using bitwise shifts. By using the format (1 << BIT) it is much easier to read the programmer's intent in the code. After clicking KOPIUJ, możesz wrzucić kod prosto do swojego IDE. W prawej sekcji DECODED VALUES widzisz na żywo przeliczenie aktualnego stanu na UINT32, HEX i pełen string BINARY.
