Enabling The Smart Society Renesas MCUs already

This class will show you how Renesas is developing

5 Enabling The Smart Society 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. 5

6 Agenda Firmware Integration Technology (FIT) Introduction FIT Modules FIT Foundation (Renesas BSP - r_bsp) FIT Plug-In (E2Studio) Lab 6

7 FIT Intro 7

8 The Problem MCUs continue to become more complex Software becomes more complex as well Project schedules do not always scale accordingly CAN 8

9 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 9

10 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 10

11 FIT Philosophy Provide strong foundation to build on Ease of integration and use is paramount Efficiently manage available resources MCU Resources Functionality 11

12 Coding Standards & FIT Coding standards give rules for individual files FIT gives rules for middleware as a whole FIT CS 12

13 FIT Modules 13

14 FIT Module Structure 14

15 Interface File Example r_rspi_rx_if.h /**************************************************************************** Typedef definitions ****************************************************************************/ /* Enumeration for common chip selects. */ typedef enum { NO_DEVICE_SELECTED=0, SDMICRO_SELECTED, FLASH_SELECTED, WIFI_SELECTED, LCD_SELECTED } device_selected_t; /*************************************************************************** Public Functions ****************************************************************************/ bool R_RSPI_Init(uint8_t channel); bool R_RSPI_Select(uint8_t channel, device_selected_t chip_select); bool R_RSPI_Deselect(uint8_t channel, device_selected_t chip_select); bool R_RSPI_BaudRateSet(uint8_t channel, uint8_t divisor); 15

16 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 16

17 readme.txt Quick reference with relevant information RX62N, RX62T, RX630, RX63N UART CMT r_module_1 Instructions: * Add xxx.c to your project * Add xxx2.c to your project * Add an include path to x * Configure through xx.h 17
