Configuring AVR128DA48 for Real-Time CAN Bus Communication
Hi @Dtynin This architecture u picked is well-suited for your application, given the robustness of the CAN Bus protocol in industrial environments. To ensure reliable, real-time data transmission:
Assign unique
CAN IDs to each sensor, with higher priority for critical sensors like vibration.
Optimize the CAN Bus speed according to your system’s bandwidth and distance requirements, typically between 125 kbps and 1 Mbps.
Leverage the AVR128DA48's message buffers to handle multiple nodes and avoid data loss during high-traffic periods.
Consider using an RTOS to schedule and prioritize tasks efficiently, ensuring real-time processing. Additionally, the AVR128DA48’s error-handling features will help maintain data integrity.
For future scalability, be mindful of potential bus traffic increases, and consider segmenting the CAN network if you plan to expand the system. This approach ensures reliable and efficient operation while maintaining flexibility for growth.5 replies
