 FIT Modules

 FIT Foundation (Renesas BSP - r_bsp)

 FIT Plug-In (E2Studio)

 Lab

FIT Intro

The Problem

 MCUs continue to become more complex

 Software becomes more complex as well

 Project schedules do not always scale accordingly

CAN

How is Renesas helping?

 FIT = Firmware Integration Technology

 FIT is a global set of Renesas standards enabling creation of quality, easy-to-use, interoperable firmware that addresses your needs

What is FIT?

 FIT is a set of rules and guidelines to help you get to market faster and easier

 Examples of what we have improved:

 Insertion into customer’s project

 Integrating multiple modules

 Simple configuration

 Common documentation practices

 Common file and directory structure

 Resource sharing for projects with multiple tasks

 Strong foundation to build code on top of

 Mixture of compile-time and run-time configuration options

FIT Philosophy

 Provide strong foundation to build on

 Ease of integration and use is paramount

 Efficiently manage available resources

MCU

Coding Standards & FIT

 Coding standards give rules for individual files

 FIT gives rules for middleware as a whole

FIT Modules

FIT Module Structure

Interface File Example

 r_rspi_rx_if.h

/**************************************************************************** Typedef definitions

****************************************************************************/ /* Enumeration for common chip selects */

****************************************************************************/

bool R_RSPI_Init(uint8_t channel);

bool R_RSPI_Select(uint8_t channel, device_selected_t chip_select);

Configuration File Example

 r_flash_api_rx600_config.h

 Enable ROM Programming

 Ignore Lock Bits

 Data Flash Background Operations

/*************************************************************************** ENABLE BGO & NON-BLOCKING DATA FLASH OPERATIONS

****************************************************************************/ /* If this is defined then the flash ready interrupt will be used and

FlashAPI routines that deal with the data flash will exit after the

operation has been started instead of polling for it to finish */

#define DATA_FLASH_BGO

FIT Foundation

r_bsp Framework

 Provides Board Support Packages for different boards

 Benefits:

 Foundation to build code on

 Has all files to get MCU up and running

 Makes it easy to write code for multiple MCU groups

 Can write code that automatically configures itself for chosen MCU

r_bsp Structure

Custom BSP

Configuring the BSP

 Configurations done through r_bsp_config.h

 Reference configuration provided in board folder

 Many options

Heap Stack

Different Levels

FIT Plug-In

E2Studio Plug-In
