Configuring AVR128DA48 for Real-Time CAN Bus Communication
I'm designing the system architecture for a Smart Industrial Monitoring System using the AVR128DA48 microcontroller and the CAN Bus protocol for communication between multiple sensors and a controller. I've chosen temperature, pressure, and vibration sensors. I plan to set up the microcontroller as the main CAN node, which collects data and processes it locally. Could you confirm if this architecture would work, or suggest any changes?
Also, how can I configure the AVR128DA48 to handle data transmission in real-time over CAN, ensuring that no data loss occurs when dealing with multiple nodes?

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.@Alien Queen Alright thanks
