Buffer Utilities

Device-agnostic C++ header-only utilities for efficient in-memory buffering.
Originally developed for the Ant Worker ESP32 firmware fleet, but designed to be fully portable across systems.

Included Components

Byte Buffer:

• Lightweight sequential reader/writer over a raw byte array.
  • No dynamic memory allocation
  • Little-endian and big-endian support
  • Separate read/write cursors for flexible use

Message Buffer:

• Small framed-message reader/writer for packetized communication.
  • 1-byte type and 1-byte payload length header
  • Safe sequential writing and reading of payloads
  • Designed for small transports (LoRa, BLE, ESP-NOW)

Ring Buffer:

• Fixed-capacity circular buffer (ring buffer) for any T type.
  • Non-blocking push/pop
  • Supports move and copy semantics
  • Constant memory overhead

Highlights

• Zero dynamic allocation: All memory is user-supplied or static.
• Header-only: Just include and use.
• Embedded-safe: Minimal dependencies, predictable behavior.
• Cross-platform: No ESP32 or device-specific code.
