Renesas "RX Family".
The RX family is the successor of both:
- Hitachi's H8 ( Renesas "H8", EN.Wikipedia "H8 Family", DE.Wikipedia "Renesas H8" ).
- Mitsubishi Electric's M16C ( DE.Wikipedia "M16C" ).
The RX111 may be configured to handle little endian and big endian, due to the origin from Hitachi and Mitsubishi.
Due to the Harvard architecture, writing of Flash during normal CPU and board operation is possible and a standard feature.
The RX family is for industry automation ( 24x7x... 10 or 20 years) use only, not for automotive ( just 8000h lifetime guaranteed ) use.

The free Renesas "C/C++ Compiler Package for RX Family" - The free edition of the RX compiler has a code limit of 128KBytes, while the largest RX CPUs of 2013 just have 128KBytes Flash .
The free IDE Renesas "e2 Studio" ( formerly: “Carpet Studio” ).
- Code generation.
  - With “e2 Studio” 2.1, there is a new code generator. Result: C source code.
  - Renesas "Application Leading Tool (Applilet)" ( formerly: NEC Applilet ) for RX111. Result: C source code. Since “e2 Studio” 2.1 of 2013-10 this tool is integrated in the IDE “e2 studio”.
  - Renesas "Peripheral I/O Drivers"
    - For RX600, there is a driver generator. Result: C library.
      - Renesas "Peripheral Driver Generator V.2.00 Published (for the RX600 Series of MCUs)", 2010-08-05.
      - Renesas "Peripheral Driver Generator".
- Support of realtime operating systems:
  - Codegenerator support for FreeRTOS was announced, in 2013-10 to be implemented soon.
  - Micrium II, III.
  - SEGGER Microcontroller - embOS.
The free IDE Renesas "High-performance Embedded Workshop" ( HEW ) - Just for RX200 and RX600. Not for RX111.
The free IDE with C/C++ compiler KPIT Cummins Infosystems Limited "KPIT GNU Tools" for RX targets.
Both RX compilers support full C++ standard .

IAR "IAR Embedded Workbench for Renesas RX" - The free Kickstart edition is limited to 64KBytes of code.

The free Renesas "Flash Development Toolkit [Programming software]".
- There is a full-blown “GUI” version and a “Basic” version for production, which may be used both by GUI and by console ( and which is so scriptable ).
- How to flash:
  1. Select “Generic Boot Device”:
    1. USB Direct.
    2. E1.
    3. Serial.
  2. Clockspeed:
    1. “Enter the CPU crystal frequency” = 12.
    2. “Main Clock” = 8.
    3. “Peripheral Clock” = 4.
Debugging is possible even with bootloader installed , e.g. in opposite to the Atmel 8-bit hardware.

“Renesas Web Compiler”.
- SAKURA BOARD for the Gadget Renesas Project - With “Renesas Web Compiler” login.

Renesas Rulz "RPBRX111".
Renesas "YRPBRX111 (For RX111)".
Glyn "ENESAS RX111 Workshop" - Download of development software “Renesas E2 Studio” for WIndows. A free license key is generated during installation of “Renesas E2 STudio” .
My target board: “Rx100 → Rx111, 64pin, R5F51115AxFM”.
“GUI DEMO” is the original firmware for my board.
A host server application to display graphics in a browser, written in Pyton, is part of the workshop material. See “WSRX111 / USB LIBUS / HostPC”.
If the bootloader installed on the eval board, should be killed someday somehow, you may ask a distributor ( e.g. Glynn ) to send you a Motorola Hex file with the data...

Renesas V850 Family → CAN bus ports which can run in different speeds ?!.
EN.Wikipedia "V850".
ucLinux is a operating system with V850 support → See Linux.
The V850 family is dededicated for automotive use only ( just 8000h lifetime guaranteed ) , not for industry automation ( 24x7x... 10 or 20 years).
