Feature Overview and Basic Operations

Feature Overview​

The monitoring function of MicroPeckerX CAN FD Analyzer captures frames on the connected CAN / CAN FD bus in real time and provides the capabilities listed below.

Feature	Description
Real-time multi-channel monitoring	Monitor data from up to eight connected channels simultaneously.
Log file output	Automatically saves frame data as CSV text files to a folder you specify on the PC.
Display mode switching	• Single View: displays one channel using the full screen. • Dual View: places two channels side by side for comparison.
Automatic protocol detection	Automatically detects CAN versus CAN FD and shows the data in the optimal format.
Each ID function	Overwrites the display with only the latest frame for each CAN ID so that you can instantly grasp the current status even with large traffic volumes.
Filter & label display	• Filters: narrow the frames shown in the log view. • Labels: assign custom labels to specified frames.
Trigger function	Starts or stops logging automatically when the configured conditions are met.

These features let you monitor multiple buses efficiently and identify the required data immediately.

In this chapter, the terms monitoring and logging are used with the definitions below.

Description	Monitoring (a.k.a. monitor)	Logging
Operation	Real-time display: shows the data captured from the CAN bus in the GUI.	File storage: automatically saves the captured data to CSV files in a designated PC folder.
Data retention	Temporary memory: the data lives only in application memory and is cleared when you close the application.	Persistent storage: saved logs remain after the application exits, enabling later analysis and sharing.
