libingenialink - Motion and communications library for Ingenia servodrives

libingenialink is a portable, pure C implementation library for simple motion control tasks and communications with Ingenia drives.

What it can do

The library provides:

Simple motion control functions (homing, profile position, etc.)
Communications API for Ingenia Summit Series drives (multiple protocols supported)
Load and use IngeniaDictionary XML dictionaries
Operate directly using units (e.g. degrees, rad/s, etc.)
Register polling and monitoring for scope applications
Servo listing and monitoring
Object oriented interface
Thread-safe communications
Descriptive and detailed error messages

Building libingenialink

Actually, libingenialink only supports Windows OS, but Linux support is coming later this year.

libingenialink depends on libxml2 and SOEM. A couple of sections below you will find some instructions on how to build and install them. libingenialink can be built and installed on any system like this:

cmake -H. -B_build -DCMAKE_INSTALL_PREFIX=$INSTALL -DWITH_PROT_ETH=ON -DWITH_PROT_ECAT=ON
cmake --build _build
cmake --build _build --target install

Note that a INSTALL is the installation folder.

Build options

The following build options are available:

DWITH_PROT_ETH (ON): Build ETH protocol support.
WITH_PROT_ECAT (ON): Build ECAT protocol support.
WITH_EXAMPLES (OFF): When enabled, the library usage example applications will be built.
WITH_DOCS (OFF): When enabled the API documentation can be built.
WITH_PIC (OFF): When enabled, generated code will be position independent. This may be useful if you want to embed ingenialink into a dynamic library.

Furthermore, standard CMake build options can be used. You may find useful to read this list of useful CMake variables.

Dependencies

As mentioned before, libingenialink depends on libxml2 and SOEM, both referenced in the external folder as submodules. Therefore, if building them make sure to initialize the submodules first:

git submodule update --init --recursive

Below you can find some building instructions for dependencies. Note that INSTALL is the installation folder.

libxml2

Athough libxml2 is multiplatform, the building process can be somewhat painful on some systems, specially on Windows. This is why we provide a CMake script to build it on the systems we support. It can be built and installed like this:

cd external/libxml2
cmake -H. -B_build -DCMAKE_INSTALL_PREFIX=$INSTALL
cmake --build _build --target install

SOEM (EXPERIMENTAL)

In order to use the embbedded master communications of ingenialink (still in development), you must install SOEM libraries as an external package.

cd external/SOEM
cmake -H. -B_build -DCMAKE_INSTALL_PREFIX=$INSTALL -DCMAKE_POSITION_INDEPENDENT_CODE=ON
cmake --build _build --target install

Coding standards

libingenialink is written in ANSI C (C99), so any modern compiler should work.

Code is written following the Linux Kernel coding style. You can check for errors or suggestions like this (uses checkpatch.pl):

cmake --build build --target style_check
