Burst Transmit

Burst Transmit sends frames back-to-back without idle time to stress the CAN bus. Two modes are available:

  • 1 Frame Mode: Repeatedly send one frame.
  • Log Mode: Replay all frames from a log file in burst form.

1 Frame Mode​

  1. Open Simulation Window and select BurstTransmit.
  2. Choose 1 Frame Mode.
  3. Configure the frame (protocol, Std./Ext., ID, Type, DLC, payload via Data Set, Bit Rate Switch for CAN FD).
  4. Start monitoring. The frame is transmitted continuously until you click Stop.

Use this mode to evaluate how ECUs behave under near-100% bus utilization. You can define any ID and payload.

Log Mode​

  1. Select Log Mode.
  2. Load a MicroPeckerX log file (error records are skipped).
  3. Optionally enable Loop, set Offset before playback, or press Stop to end transmission manually.
  4. Start monitoring to send the log contents in burst form.

Event Triggers​

You can delay the start of burst transmission until a trigger fires:

  • None
  • Receive Trigger / Receive Trigger (CAN FD): Start when a frame with the specified ID arrives.
  • Ext Trigger: Reserved for future use.
  • Log Trigger: Start when a monitoring log condition matches.
  • Key Trigger: Start when a key combination is pressed.

Trigger settings share the same configuration UI as Log Replay. Specify ID format, ID value, and frame type for receive triggers, or use the Log Trigger dialog for complex conditions.
