Utility Library

The project contains portable C++ code for

• encoding/decoding numeric values to/from raw bytes
• sharing pointer on embedded platforms
• storing data in AVL tree
• managing raw data in a buffer with read/write pointers, auto-resizing
• improving output from unit tests
• tracking number ranges for calculating delta, mean or median

Build

Set up the build following an example from cmake-helpers project.

Utility Classes

AvlTree

Implements an AVL tree. See usage examples in avl_tree_test.cpp

Buff

Implements dynamicaly resizable buffer. Provides read/write pointer tracking. See usage examples in buff_test.cpp

Misc

Implements various utility functions such as

• Translation between value ranges
• Calculation of angle delta squared
• Computing modulo with negative numbers
• Setting/clearing bits at given byte addresses
• Converting degrees to radians and vice versa
• Converting binary data to human-readable hex representation

See usage examples in misc_test.cpp

SharedPtr

Implements basic shared pointer to be used on an embedded platform. See usage examples in shared_ptr_test.cpp

Sorters

Implements sorting algorithms for sorting a plain-old-data array. See usage examples in sorters_test.cpp

SpinLock

Implements a basic spin lock for x86.

TestHelpers

Implements useful facilities for when unit testing. See usage examples in unit tests, example: value_codec_test.cpp

ValueCodec

Implements number encoding and decoding facilities accounting for target host order. See usage examples in value_codec_test.cpp

ValueTracker

The class keeps track of numeric values so as to calculate the delta, mean or median between them. See usage examples in value_tracker_test.cpp
