Feature Overview and Basic Operation

Feature Overview

The simulation function of MicroPeckerX CAN FD Analyzer can flexibly control transmission on the CAN bus in the following modes. Configure settings in Simulation Window.

Function	Description
Simulation mode selection	None (monitor only) / Send Frame (slot transmission) / Log Replay / Burst Transmit / Direct Transmit / Extended (plugin extension)
Slot transmission (Send Frame)	Automatically transmits frames with various conditions using up to 28 slots: - Periodic - Periodic Trigger - Event - Event Periodic
Direct Transmit	Immediately transmits configured frame by pressing Send button. Suitable for tests and manual operation.
Log Replay	Replays loaded log files as transmission (up to 1.2 million records), with loop playback, offset/replay interval settings, and trigger start.
Burst Transmit	Continuously transmits a single frame or log burst (log mode), with loop/offset/trigger control.
Trigger linkage	In all transmission modes, transmission can start by conditions such as Receive Trigger, Log Trigger, Key Trigger.
Detailed settings	Fine parameter tuning such as CAN/CAN FD, frame ID, DLC, data, increment settings, transmission count and interval.

This enables easy execution of realistic frame transmission, bus load tests, reproduction experiments, and manual debugging with flexible patterns.

Basic Operation (Example: Periodic Transmission Frame Setup)

This section describes periodic transmission frame setup flow.

Open Simulation Window
Select Simulation Window from menu or toolbar.

Select Send Frame mode
Click Send Frame in Simulation Mode.

Open CAN/CAN-FD Frame Setting dialog
Click in Simulation Window.

Configure periodic transmission
Set periodic transmission in CAN/CAN-FD Frame Setting dialog.

Item	Description	Example
Mode	Transmission mode	Periodic
Protocol	CAN or CAN-FD	CAN-FD
ID	CAN ID	100
DLC	DLC	64
Cycle	Transmission cycle	100ms

Set data
Click Data Set in CAN/CAN-FD Frame Setting dialog to configure payload.

Close dialogs
Click OK in both dialogs to finish configuration. The configured frame appears in Frame Slot List in Simulation Window.

Enable transmission by checking the left checkbox of each frame. If checked, frame transmission starts when monitoring starts.
You can also toggle checkbox ON/OFF during monitoring.

Start monitoring
Select Command -> Start, click , or press F5.

Simulation Window Screen Description

CAN simulation settings are configured in Simulation Window.

No.	Screen Menu	Description
1	Ch selection tab	Selects target channel.
2	Simulation Mode	Selects simulation mode. - None: monitor mode (no transmission) - Send Frame: simulation mode - Log Replay: log replay mode - BurstTransmit: burst transmit mode - Extended: extended mode
3	Setting pane	Setting pane for transmission data, etc. Content changes depending on selected mode.

Monitor mode

If None is selected in Simulation Mode, the system enters monitor mode and does not transmit.
In this mode, configuration for selected channel can be cleared.

Screen Menu	Description
All Clear button	Clears all simulation settings of selected channel.
Send Frame Clear button	Clears all Send Frame settings of selected channel. Direct Transmit settings are not cleared.
