CAN Example

This example demonstrates basic CAN communication setup and usage in EcuBus-Pro.

Network Structure

The example consists of three nodes:

• Node 1 (Brown) - Signal generator node
• Can IA (SkyBlue) - Interactive analysis interface
• SIMULATE_0 (Blue) - CAN bus simulator

The nodes are connected in a CAN network topology, with Node 1 sending signals through SIMULATE_0 device, which can be monitored and analyzed in Can IA.

Features Demonstrated

1. Message Transmission

   • Node 1 runs a script that periodically updates signal value
   • Signal: VCLEFT_liftgateLatchRequest (cycles through values 0-4)
   • Update interval: 1000ms

   // Node 1 script
   import {setSignal} from 'ECB'
   let val = 0;
   setInterval(() => {
       setSignal("Model3CAN.VCLEFT_liftgateLatchRequest", (val++) % 5);
   }, 1000);

2. Data Visualization

   • Real-time signal graphing in Can IA
   • Message trace logging
   • Network topology view

3. Interactive Controls

   • Start/Stop frame sending
   • Signal value inspection

4. Graph

   • graph signal VCLEFT_liftgateLatchRequest

   

Usage

1. Load the example configuration file (Can.ecb)
2. The network topology will be displayed in the Network view
3. Start the simulation to see Node 1 generating signal values
4. Use Can IA interface to:
   • Monitor signal changes
   • View message trace
   • Watch real-time signal graph
   • Inspect message details

This example demonstrates how to set up automated signal generation and monitoring in EcuBus-Pro, making it ideal for learning basic CAN communication concepts and signal analysis features.
