Sunny Giken CAN Communication Software CioRy Communication Middleware CAN/CAN FD Package

Manufacturer: Sunny Giken Inc.
Model : CAN communication software

Features

The CioRy CAN/CAN FD Package is optimized embedded software for CAN and CAN FD communication. It includes a modular middleware setup with a CAN driver, COM, and NM.
The package handles message transmission, reception, sleep/wake-up, and error notifications. Its source code complies with MISRA-C, ensuring high software quality for automotive ECUs.
Using this package shortens development time and allows users to focus on application development.

1. High-quality communications middleware reduces development time

The CioRy Communication Middle CAN/CAN FD Package is optimized for embedded CAN and CAN FD communication.
It includes modular components such as the CAN driver, COM, and NM.
The middleware handles message transmission/reception, sleep/wake-up, and error notifications.
The source code follows the MISRA-C standard for automotive ECU software.
Using this package reduces CAN development time and lets users focus on application development.

2. Implementation of functions necessary for CAN communication for in-vehicle ECU

The CioRy CAN/CAN FD Package provides essential functions for automotive ECU communication.
It includes a fail-safe feature that notifies the application of communication errors.
The package is built on proven in-vehicle CAN development expertise, ensuring reliability.

Function
Transmission timing control function	Periodic sending event Sending event + periodic sending
Fail-safe function	Reception interruption detection DLC check Transmission deadline detection function Bus off detection function Message register fixation check judgment

3. Signal-based data access from applications

CioRy communication middleware manages CAN and CAN FD message transmission, reception, and periodic processing.
Applications can send and receive messages anytime using signal names.
CioRy handles packing and unpacking of signal data, so applications don’t need to manage CAN/CAN FD frame details.

4. Low-load, small-ROM-size CAN communication software

The CioRy CAN/CAN FD Package is optimized middleware for automotive ECUs, offering low CPU load and small ROM size.
It uses proprietary clustering technology to reduce module overhead and improve processing speed.
This design enables smooth operation even on low-end microcontrollers. The package supports both CAN and CAN FD communication.

Communication middle	ROM	RAM	Measurement conditions
CAN	13.3KB	632byte	RL78/F14 Compiler: IAR CAN communication speed: 500Kbps Number of transmitted frames: 5 frames Number of received frames: 10 frames Number of transmitted signals: 50 signals Number of received signals: 100 signals
CAN FD	16KB	800 bytes	RH850/F1K send/receive 2 frames each (DLC64) receive queue 25 stages

5. Scalability

CioRy’s CAN/CAN FD middleware can be expanded with optional modules.
For security, message authentication is supported using the AUTOSAR-compliant CioRy security option.
For full AUTOSAR support, a package is available with AUTOSAR-compliant RTE, OS, and CAN NM modules.

6. Easy configuration settings

The CioRy Configurator offers simple setup with only the minimum required settings.
Signal settings for message transmission and reception are entered in an Excel-based table.
The tool reads this table and automatically generates source code based on the configuration.

7. Transition to AUTOSAR CP

When migrating to AUTOSAR, full SW-C architecture may not be needed right away.
The CioRy package can be used with only the CAN communication stack, without RTE or OS.
RTE and OS packages can be added later as system needs grow.
