BUSMASTER E2E transmit protection tutorials

Follow these six tutorials using BUSMASTER 3.2.2.51 (Build 571). The screenshots show the Chinese interface. In another version, look for E2E on the CAN ribbon and the Dynamic Message column in the transmit list.

End-to-end (E2E) protection adds a counter and checksum to the application payload so the receiver can check each frame against the communication specification. BUSMASTER computes these fields on each CAN or CAN FD transmission. You can use the existing manual send, period and send count controls.

Learning sequence

1. Send your first protected frame with AUTOSAR P01 / BOTH and verify four frames at the receiving end.
2. Select a profile and configure its parameters, including DataID, counter and header positions.
3. Use DBC signals for protection fields and verify the derived layout.
4. Manage algorithms and build a custom DLL using the bundled examples.
5. Send periodically, reset counters and save projects.
6. Verify received frames and troubleshoot.

Practice files

• Offline HTML tutorial (ZIP, Chinese) for Build 571. For log locations on other builds, see Collect support logs and submit feedback.
• Teaching DBC for chapter 03. Chapter 01 works without a DBC.
• Four P01 reference payloads (CSV)
• Source and standalone projects for the two example DLLs
• Notes on the practice files (Chinese)

Start with basic transmit and receive if you need to set up your analyzer.

Supported operations

BUSMASTER provides transmit-side Protect for CAN and CAN FD with AUTOSAR P01, P02, P04, P05 and P06. At the receiving end, use the ECU or test tool’s E2E Check implementation. Match the algorithm, fields, payload length and parameters to the peer’s communication specification. The CAN ID, DataID, period, channel and termination in these exercises are example settings.
