 Renesas MCUs already offer you the hardware you need to
make a device that will thrive in the Smart Society. Smart
and efficient software is also needed though. This class will
show you how Renesas is developing software that will make
your application development easier and faster.

The Problem
 MCUs continue to become more complex
 Software becomes more complex as well


Project schedules do not always scale accordingly

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

Coding Standards & FIT
 Coding standards give rules for individual files
 FIT gives rules for middleware as a whole

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

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
