 Challenge:

“MCUs continue to become more complex especially when creating applications to enable the Smart Society, and

therefore the Software becomes more complex as well

However, project schedules do not always scale

accordingly.”

 Solution:

“Renesas is introducing an Eclipse-based Integrated

Development Environment, providing powerful and flexible features that ease and accelerate creation and debugging of embedded code.”

Introduction

What are the Most Important Factors in Choosing a Processor?

Software Development Tool Requirements

Low cost / free

The Quest to Unify Renesas’ In-House Software Development Tools (IDEs)

(former NEC Electronics IDE)

Renesas e clipse e mbedded Studio, a.k.a…

Quick Recap on Eclipse

 Open source, free of charge IDE platform for C/C++

software development (when combined with CDT)

 Community effort - Collaboration by MANY developers:

IBM, Oracle, Cisco, Intel, etc.

 Overall project management by the Eclipse Foundation

( www.eclipse.org ), founded in 2004

 Extensible plug-in system

 Similar to Firefox Add-ons

 Allows Renesas to add build support for specific MCUs as well as support for device dependent debug hardware

 Allows users to customize their IDE by adding 3 rd party plug-ins, e.g editors, compilers, bug trackers, version control software, RTOS awareness, etc.

Why Did We Choose Eclipse?

 Eclipse is becoming the de-facto standard IDE for embedded software development in Europe and the US

 Eclipse is gaining momentum because users can…

 …standardize their development tools

(less training, faster development)

 …take advantage of a large variety of available plug-ins for

embedded development from a large variety of vendors

 …develop their own plug-ins

 …get easier technical support

(main product used by many people)

 …take advantage of numerous mature IDE features

(particularly in editor)

 …save money over proprietary development tools

(especially when combined with free GNU compilers)

e 2 studio Features

v3.6 – Helios CDT v7

Automatic Toolchain Detection

 Installed RX, SH and KPIT GNU toolchains are automatically detected and installed for use in e 2 studio when the product

is launched

Project Generation Wizard

 An easy way to get started on a certain family / device!

Powerful Editor Functionality

Automatic

code completion

Code templates

Automated code constructs (if, while, do while etc)

In edit processor checking

pre-Auto variable completion while writing

Extended Project Properties / Build Options

 Toolchain-related properties specific to a project or file

 Code generation, linking and archiving options

 Standard C library generation and usage options

 Linker script editing

Renesas Debug Perspective

Renesas Debug View

 Controls execution of code on target

 Instruction stepping mode

 Call stack

 Select stack frame to inspect related local variables

IO Registers View

 Presentation of all IO Registers of the MCU

 Also known as special function registers

 Register sets defined in a target-specific IO file

Eventpoints View – Sets Complex Breakpoints

 Before PC eventpoints: Hardware breakpoints (Address)

 Event Break eventpoints: Trigger on Data Access (R/W)

 Trace eventpoints: Trigger start, stop, and recording of Trace

 Combine eventpoints with OR, AND, and SEQUENCE logic to create complex triggers

Trace View

 Trace acquisition depending on hardware capabilities:

 Branch, Branch and Data, Data

 Presentation modes:

 Bus mode, Disassembly mode, Source mode

Profiling View (new in v1.1)

 e²studio uses the trace data to determine times spent in each area of code

 This means profiling can be supported by any device / debugger that supports trace

 To view profiling results the Enable Profile Toolbar button must be enabled

Coverage View (new in v1.1)

 Supports testing software and inspecting/reporting the specific lines of target application source code that were executed during a particular run

 Currently only supported by RL78 IECUBE emulator

Real-Time Memory View

00000001

 Shows real-time updates for a chosen memory area

Real-Time Expression View

 Shows real-time updates to global and static variables data

01

Real-Time Chart View

 Allows multiple expressions to be graphed over time

HEW project import (new in v1.1)

 Allows RX and SH HEW project import into Renesas e²studio

 Notes:

 HEW versions below v4.07 are not officially supported

 Only Compiler, Assembler, Linker, and Library Generator phase settings will be imported

Packages, Delivery, Updates, and Support

 Option 1: Complete e 2 studio IDE installer

 Option 2: Renesas Plug-ins only

 Can be installed from within an existing Eclipse (Helios) + CDT environment using the Eclipse IDE software update feature

Product Delivery and Support

 Delivery via CD installer (e.g in kits) as well as via web download

 IDE itself is free of charge – just add free KPIT GNU toolchains for a free development environment

 Product bundled with Renesas toolchains uses the current

Renesas pricing models – First implementation: RX compiler

Product Updates

 Product Updates

 Product updates can be done from within e 2 studio

 Help => Install New Software

– e2studio Update Site

-http://www2.renesas.eu/_custom/software/ree_eclipse

 Website version will keep step with latest in-app update – 1-2 week delay possible
