Changelog

[3.0.0] – 2025-06-19

🚀 Added

• Runtime backend switching: bind to SPIFFS, LittleFS, SD (or any fs::FS*) and swap on the fly.
• Unified file & directory API: single interface for open, size, exists, recursive list, create, clear, remove, rename.
• Streaming I/O support: line-limited reads, cursor movement by lines, plus a UI-callback hook to keep interfaces responsive.
• Full filesystem formatting: wipe entire volume or clear just one directory.
• Transport layer: new transportAccess_t subclass for one-call copy/move of files or folders between any two FS backends, with automatic naming conflict resolution and optional cut semantics.
• Enhanced benchmarks: I/O speed tests report bytes per millisecond with progress dots.

✨ Changed

• Refactored into .h/.cpp modules; moved internal pointers into private scope.
• Switched all path arguments to const char* for minimal RAM footprint.
• Improved debug output using Serial.printf under Debug_Serial_Memory.
• Added initTransport.h alongside initMemory.h for transport utilities.

🔄 Breaking Changes

• None for existing v2.0.0 code—your sketches will compile unmodified under v3.0.0.
• To use file-transfer features, include the new transport header and instantiate transportAccess_t.

Changelog

[2.0.0] – 2024-12-10

🚀 Added

• memoryAccess_t class with a constructor that accepts an fs::FS* instance:

  memoryAccess_t storage(&SPIFFS);

• type(uint8_t cardType) method to detect SD card type (MMC / SDSC / SDHC)
• testIO(const char* path) method for read/write benchmark (I/O speed)
• All path parameters now use const char* instead of String for lower overhead
• Renamed debug macro to Debug_Serial_Memory

✨ Changed

• Renamed memory_t → memoryAccess_t
• Moved fs::FS* typeMemory pointer into private class scope
• Split implementation into header (.h) and source (.cpp) files
• Improved Serial debug output using Serial.printf()

🔥 Breaking Changes

• Initialization
  • Before (v1.x):

    memory_t mem;
    mem.init(&SPIFFS);

  • Now (v2.x):

    memoryAccess_t mem(&SPIFFS);

• Path parameters
  • Changed from listDir(String path, …) to listDir(const char* path, …)
• Debug macro
  • Before: #define MemorydebugSerial
  • Now: #define Debug_Serial_Memory

🐞 Fixed

• No critical bug fixes; v1.0.0 was stable.

[1.0.0] – 2023-12-19

🚀 Added

• Initial release of the memory_t utility struct
• init(fs::FS* fs) – bind to a SPIFFS, LittleFS or SD instance
• Directory APIs:
  • listDir(String path, uint8_t levels) – recursive listing
  • createDir(String path)
  • removeDir(String path)
• File APIs:
  • read(String path)
  • write(String path, String message) – overwrite or create
  • append(String path, String message)
  • rename(String oldPath, String newPath)
  • remove(String path)
• Optional serial debugging via #define MemorydebugSerial
