Sunny Giken LIN Communication Software CioRy Communication Middle LIN Package

Manufacturer: Sunny Giken Inc.
Model : LIN communication software

Features

The CioRy LIN Master and Slave Packages provide embedded LIN communication middleware and a PC-based configurator for automotive ECUs.
Each package includes a LIN driver, COM, and Network Management (NM) for fast, high-quality LIN application development. The configurator simplifies communication settings.
CioRy is already used in over 40 ECU projects across 27 companies, including automakers and parts suppliers.

1. High-quality communications middleware reduces development time

The CioRy LIN Package is optimized embedded software for LIN communication. It supports LIN Consortium Rev. 2.1 and offers separate packages for master and slave nodes.
The middleware manages message transmission/reception, sleep/wake-up, and error notifications. Its source code follows MISRA-C, the standard for automotive ECU software.
Using this package reduces LIN development effort and lets users focus on application logic.

2. Implementation of functions necessary for LIN communication for automotive ECUs

The CioRy LIN Package provides essential functions for LIN communication in automotive ECUs.
It includes signal transmission/reception, sleep/wake-up, and a fail-safe feature for error notification.
Built on proven in-vehicle LIN development expertise, it ensures reliable use and easy integration.

LIN Node	Function
LIN Master	Sending Function	Master Header transmission/Header + Response transmission Master Schedule Start/Stop/Switch Master Go-to-sleep command transmission
	Receiving Function	Master response received
	Send/receive control	Schedule start/end control Schedule switching control
LIN Slave	Sending Function	Slave response transmission
LIN Slave	Receiving Function	Receiving Slave response
Common	Fail-safe function	Bus inactive monitoring Abnormal state detection LIN controller abnormality Transmitted message abnormality Received message abnormality

3. Signal-based data access from applications

CioRy communication middleware handles LIN message transmission, reception, and periodic processing.
Applications use signal names to send and receive data.
CioRy manages packing and unpacking of signals, so applications do not need to handle LIN frames directly.

4. Low-load, small-ROM-size LIN communications software

The CioRy LIN Package provides essential ECU functions with low CPU load and small ROM size, making it ideal for automotive microcontrollers.

Communication middle	ROM	RAM	Measurement conditions
LIN Master	6.3KB	>323byte	RL78/F14 Compiler: IAR LIN communication speed: 19.2Kbps LIN transmission frame count: 5 frames LIN reception frame count: 5 frames

5. Easy configuration settings

The feature of the CioRy Configurator is that it makes configuration extremely easy.
Signal settings can be entered in an Excel-based table and loaded into the tool. It also supports LIN Description Files (LDF) for communication configuration.
Once settings are complete, the tool generates source code based on the input.
