Introduction

Purpose

This training course describes the configuration and session features of the High-performance Embedded Workshop

(HEW), a key tool for developing software for embedded systems that use microcontrollers (MCUs) from Renesas Technology Corp.

Objectives

Describe the basic functions of configurations and sessions Explain the effective use of these features

Show the steps used to generate new configurations and sessions

Workspace and Projects

Workspace

Contains one or more projects Simplifies project management

Project

Contains multiple configurations and sessions

Workspace Project A Configuration Configuration Session Session Project B Project C

Projects are specific to a target MCU. However . . . • HEW configurations let you select different sets of toolchain options to be applied to the files in the project when it is built.

• HEW sessions allow you to select different debug targets or target settings.

Definitions

Configuration

A collection of parameter switches used for building a project HEW generates two configurations by default:

– Debug (Optimization is turned off in initial Debug configuration) – Release (Optimization is turned on in initial Release configuration)

Session

Determines which debut target is used Stores debug target parameters

– Default – Simulator – Emulator

Configuration Files

Configuration Debug Configuration _Release

Debug and Release configurations are compiled based on

initial toolchain settings

Output file using Release configuration is smaller than output

file using Debug configuration

(7)

Usage Example

7 _{Debug “Release code” in Emulator} 6 _{Debug “Release code” in Simulator}

5 _{Compile “Release code”}

3 _{Debug “debug code” in Emulator} 2 _{Debug “debug code” in Simulator}

4 _{Disconnect from target}

Effective Usage

Configurations and Sessions

Provide easy way to manipulate environmental settings

Enable quick and easy comparison of resulting code

- Size

- Performance

Allow you to add new debug targets

(proprietary or third-party types)

(9)

Create New Configuration

HEW generates new subdirectory with assigned configuration name

Click on “Build Configuration”

Click on “Add” 1

2

Type in new configuration name 3

Choose configuration on which new configuration will be based 4

Create New Session (Automatic)

Sessions are created automatically during new project generation

when Target is selected

Availability of sessions (Emulator, Simulator) depends on what

HEW components are installed

Selecting target generates session

(11)

Create New Session (Manual)

Click on “Debug Session” 1

Type in new session name 3

(12)

12

Click on “Debug Settings” 1

Set Up New Session

Select available target 2

Select debug format 3

Use placeholder filename 5

(13)

Add a New Debug Target

“New Session” wizard makes it easy to add a new target

Select “New Session”

Name new session

New session is added to toolbar 1
