Hatchling Platform

Small C++ run-time intended to be developed against on the desktop before cross compiling to an embedded target. This is minimalist programming. I wrote this for myself to have on hand for bare metal projects but welcome feedback and patches.

• #include <hx/hatchling.h>

• A lightweight streamlined reimplementation of Google Test. This code base is exhaustively tested.

• Profiling. Captures a hierarchical time-line view with a minimum of overhead. View the example profile.json file in Chrome's about://tracing view.

• Memory Management. Abstracts a range of allocation strategies behind an RAII interface.

• DMA. Cross platform DMA wrapper with validation.

• Containers. Provides a small non-reallocating subset of std::vector std::allocator and std::unordered_{ map, set, multimap, multiset }.

• Command line based console with simple C++ function binding.

• Task Queue. Provides an object oriented interface to multi-threading.

• Uses standard C99 headers as required. With the exception of host implementations where threading and time headers are included. And <new>.

• Logging and memory management available in plain C99.

• Includes a tiny and configurable printf from: https://github.com/mpaland/printf

• 64-bit clean. Intended for but not limited to use with a 32-bit target. Memory allocation, DMA and File I/O use size_t, everything else is 32-bit to keep structure layouts predictable.

• Does not use exceptions or std::type_info.
