This fork should be considered the primary fork at this point and has a few changes / fixes versus what's in this repository and is being actively maintained by the original author of this repository.
Anchor is a collection of various embedded firmware libraries developed by Skip Transport, Inc. These libraries were all developed to be easily re-usable and not dependant on a specific MCU or RTOS.
This repository is organized as a collection of libraries which are largely independent of each other. You are free to pick and chose the libraries which are most useful in your application, without needing to include them all. Each library is organized within a subdirectory, with a README providing information specific to the library.
In general, including a library is as simple as adding all the .c files
within <lib>/src to your build system as C sources to be compiled, and adding
<lib>/include to your build system's include path.
The logging library makes it easy to write out consistent and useful debug logs. This is often done over a UART connection, but the library is agnostic to the protocol being used.

The FSM library is a very lightweight set of macros and functions for defining
event-based finite state machines with enter/exit handlers for each state. See
the README within the fsm subdirectory for more information and an example.
The console library can be used to provide a debug interface to your device. The library is designed to be highly configurable to allow the user to decide between more features and code-space / runtime efficiencies.
