Lightweight ring buffer manager

Library provides generic FIFO ring buffer implementation.

Read first: Documentation

Features

• Written in ANSI C99, 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 achitecture 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
