Introduction

uGOAL describes a software package, which allows integration of of the irj45/SoM module into applications without using a full GOAL framework platform. By stripping down the required dependencies from the GOAL industrial communication framework, integration is possible into a wide range of platforms from a simple ATMEGA 8-bit CPU with 2KB of RAM up to a linux PC.

uGOAL mimics the required functionality from the GOAL framework specifically needed by the application controller framework. It is configurable in different ways to ensure compatibility with a wide range of targets. Most GOAL functionality is not available, however the CCM specific examples for fieldbus applications can be reused mostly without adaption.

Components

uGOAL contains a core which includes the basic GOAL framework functionality required for RPC wrappers. Following RPC wrappers are available for uGOAL:

API

The uGOAL based software delivery is API compatible with the GOAL based software delivery. Therefore all existing application and examples can be reused with minimal adaption. Thus the communication module user manual also applies to the uGOAL software delivery: iRJ45/SoM - User Manual .

Examples

Many examples are available:

Examples from the 2015013_irj45 folder are derived from GOAL based examples. Additional description can be found here: iRJ45 / SoM - GOAL examples .

Examples under the goal folder are developed with uGOAL in scope, thus they are generally more suitable for smaller targets (up to only 8kByte of RAM). Additional description can be found here: iRJ45 / SoM - uGOAL Examples .

Platform porting

The platform interface required for integration into an platform contains of the following functions:
