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 |
| 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.
