Feature Overview and Basic Operation
Feature Overview
The monitoring function of MicroPeckerX CAN FD Analyzer acquires and displays frame data on connected CAN/CAN FD buses in real time.
| Function | Description |
|---|---|
| Real-time simultaneous monitoring | Simultaneously monitors data from up to 8 connected channels. |
| Log file output | Automatically saves frame data as CSV text files to a specified folder on the PC. |
| Display mode switching | Single View: full-screen display of one channel Dual View: side-by-side comparison display of two channels |
| Automatic protocol detection | Automatically detects CAN and CAN FD and displays in the optimal format. |
| Each ID function | Overwrites and displays only the latest frame for each CAN ID, allowing quick grasp of current status even with large data volumes. |
| Filter & label display | Filter: narrows displayed frame data Label: assigns arbitrary labels to specified frames |
| Trigger function | Automatically controls log start/stop when configured conditions are detected. |
This allows efficient monitoring of multiple buses and instant access to required data.
In this chapter, the terms are used as follows:
| Description | Monitoring (or monitor) | Logging |
|---|---|---|
| Operation | Real-time display: data acquired from the CAN bus is shown in real time on the GUI application. | File save: data acquired from the CAN bus is automatically saved in CSV text file format to a specified folder on the PC. |
| Data retention | Temporary memory: data is stored only in application memory and is lost when the application exits. | Persistent storage: saved logs remain as files after the application exits, allowing later analysis and sharing. |
