Lightweight ring buffer manager

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
