+# CAN
+
+CAN/CAN-FD is an industry-standard vehicle bus protocol designed for reliable ECU communication in automotive applications.
+
+> [!IMPORTANT]
+> All features described in this section require a CAN DBC file. For more information about DBC files, please refer to our [database documentation](../dbc).
+
+> [!NOTE]
+> Supported Hardware:
+> | Manufacturer | Protocols |
+> |--------|-------------------|
+> | PEAK | CAN, CAN-FD |
+> | KVASER | CAN, CAN-FD |
+> | ZLG | CAN, CAN-FD |
+> | Toomoss | CAN, CAN-FD (Coming Soon) |
+
+## Device Configuration
+
+For demonstration purposes, we'll use a simulated device. You can configure the baud rate and sample point in the device settings.
+
+![alt text](image.png)
+
+## Interactive Mode and Node Scripts
+
+EcuBus-Pro offers two primary methods for CAN communication:
+* Interactive Mode: For manual frame transmission
+* Node Scripts: For automated communication using custom scripts
+
+![alt text](image-1.png)
+
+### Interactive Mode
+
+Each frame can be configured for periodic transmission or manual triggering (single-shot or key-bound).
+![alt text](image-2.png)
+
+You can add frames in two ways:
+* Manual frame configuration
+* Import from DBC database
+![alt text](image-3.png)
+
+### Node Scripts
+
+Nodes can be configured with UDS capabilities (tester) and custom scripts.
+![alt text](image-4.png)
+
+Example script for periodic signal updates:
+```typescript
+import {setSignal} from 'ECB'
+let val = 0;
+// Update signal value every second
+setInterval(() => {
+    setSignal("Model3CAN.VCLEFT_liftgateLatchRequest", (val++) % 5);
+}, 1000);
+```
+
+## Diagnostic Operations
+
+1. **Tester Configuration**
+   - Configure addressing
+   - Set diagnostic parameters
+    ![alt text](image-5.png)
+
+2. **Diagnostic Services**
+   - Configure diagnostic services
+   - Create schedule tables and sequences
+    ![alt text](image-6.png)
+
+3. **Message Monitoring**
+   - View transmitted and received messages in the trace window
+    ![alt text](image-7.png)
