# Lightweight ring buffer manager

Library provides generic FIFO ring buffer implementation.

Read first: Documentation



## Features

* Written in C (C11), compatible with ``size_t`` for size data types

* Platform independent default code - with restrictions for smaller CPU architectures (`< sizeof(size_t)`)

* FIFO (First In First Out) buffer implementation

* No dynamic memory allocation, data is static array

* Uses optimized memory copy instead of loops to read/write data from/to memory

* Thread safe when used as pipe with single write and single read entries - when CPU read/write operation for `size_t` are single instruction (ARM Cortex-M for instance)

* Interrupt safe when used as pipe with single write and single read entries - when CPU read/write operation for `size_t` are single instruction (ARM Cortex-M for instance)

* For CPU systems with smaller architecture than `sizeof(size_t)` (AVR for instance), atomic protection is required for read-write operation of buffer writes

* Suitable for DMA transfers from and to memory with zero-copy overhead between buffer and application memory

* Supports data peek, skip for read and advance for write

* Implements support for event notifications

* User friendly MIT license
