v3.0.0

Release Notes

Introduction

This document describes the contents of the Example Project Bundle for RZ/G Flexible Software Package (FSP).
The Example Projects contained within the bundle show how to write code for the various Renesas FSP modules.

Flexible Software Package is an optimized software package designed to provide easy to use, scalable, high-quality software for embedded system design.
The primary goal is to provide lightweight, efficient drivers that meet common use cases in embedded systems.
FSP code quality is enforced by peer reviews, automated requirements-based testing, and automated static analysis.
FSP provides uniform and intuitive APIs that are well documented. Each module is supported with detailed user documentation including example code.
FSP modules can be configured at build-time to optimize the size of the module for the feature set required by the application.
