Sunny Giken CXPI Communication Software CioRy Communication Middle CXPI Slave Package

Manufacturer: Sunny Giken Inc.
Model : CXPI communication software

Features

The CioRy CXPI Slave Package includes embedded CXPI middleware and a PC-based configurator for automotive ECUs.
It complies with the CXPI JASO D015 standard and supports OEM-specific communication settings. This enables quick development of CXPI-based applications.
CioRy is used in over 40 ECU projects at 27 companies, including automakers and parts suppliers.

1. High-quality communications middleware reduces development time

The CioRy CXPI Slave Package is optimized embedded software for CXPI communication. It complies with the JASO D015 (ISO 20794) CXPI standard.
OEM options can be added to meet specific automaker requirements. The source code follows MISRA-C, ensuring high software quality.
Using this package reduces development effort and lets users focus on application design.

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

The CioRy CXPI Slave Package provides essential functions for in-vehicle CXPI communication.
It includes a fail-safe feature that notifies the application of communication errors.
OEM-specific fail-safe functions can also be added to meet automaker requirements.
The package is built on proven in-vehicle communication expertise, ensuring reliable use.

Standard Features	Normal frame Event transmission Sleep/Wakeup Error acquisition
OEM option compatible functions	Reception interruption detection Transmission lock detection Bus off detection function Message register stuck check detection DLC check

3. Signal-based data access from applications

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

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

The CioRy CXPI Slave Package provides essential ECU functions with low CPU load and a small ROM footprint, making it ideal for automotive microcontrollers.
CXPI communication is achieved using UART on the microcontroller.
For RL78/F13 and F14, the required resources are:
RLIN3-UART ×1
Timer ×1.
If using the ROHM BD41003FJ-C transceiver, no external interrupt (INT) is needed. If using the Infineon S6BT112A, one external INT is required.

5. Easy configuration settings

The CioRy Configurator makes configuration simple by limiting settings to the minimum required.
Signal settings can be entered in an Excel-format table and loaded into the tool.
Once configured, the tool generates source code based on the input settings.
