This page describes the steps needed to integrate the ETL with your project.
The ETL requires no special installation. Just copy or clone the GitHub project into an appropriate directory.
For additional information pertaining to compilers, see this page.
User defined files
The user must create a file named etl_profile.h which then includes a compiler profile header.
This header is included from ETL's platform.h
An example would be:-
There are several profiles available in the ETL's src/profiles/ directory. They may either be used 'as is' or as a base
for a project specific variant.
The profiles currently available are:
Arduino_arm.h Arduino ARM targets. No OS.
armv5.h ARM compiler version 5.x. No OS.
armv6.h ARM compiler version 6.x. No OS.
cpp03.h Generic C++03. Generic target. No OS.
cpp11.h Generic C++11. Generic target. No OS.
cpp14.h Generic C++14. Generic target. No OS.
gcc_generic.h GCC generic settings. Generic target. No OS.
gcc_linux_x86.h GCC for Linux on X86 target
gcc_windows_x86.h GCC for Windows on X86 target
msvc_x86.h Microsoft Visual Studio for Windows on X86 target
ticc.h Texas Instruments Code Composer. Generic target. No OS.
Additional include directories
The compiler will normally expect paths to additional include directories to be specified
A path to the ETL's src directory must either be defined or full paths to the ETL includes must be used.
A path to the user generated etl_profile.h must be defined.
The Arduino programming platform is not supplied with an implementation of the STL. The ETL requires some parts of
the STL to compile and therefore one must be acquired. A suitable implementation may be downloaded from the
Arduino library resource; It is called ArduinoSTL.
Add #include <ArduinoSTL.h> to the start of every file that uses the ETL.
Remember to add the directory to the include path.
Although the ETL is based on C++ there is a small offshoot that is intended for C delevopers. At the present time it is
limited to a timer callback framework. To use the ECL (Embedded C Library) you must define a header named
ecl_user.h. This header will supply the definitions require to support the library on the target OS.
For an example of what must go in this header, see the version supplied for the unit tests. test/ecl_user.h
