python-saleae-cli

This is a basic command line utility to automate the Saleae Logic software.

This tool can be used to automatically take a series of shorter captures over an extended time period. For example, if a 24 hour capture can't be recorded in a single run due to memory limitations, this utility could be used to automatically take 24 captures of one hour each.

Prerequisites

Usage

The utility allows the user to set the number of captures and the duration of each capture. It also optionally supports three different save operations:

  1. save captures. If the --save-captures option is used, the utility will save each capture to the folder specified with the filename N.logicdata, where N is the index of the capture.
  2. export captures. If the --export-data option is used, the utility will export each capture to the folder specified using the default csv export options provided by the ppannuto python-saleae library (thanks for that feature!)
  3. export analyzers. If the --export-analyzers option is used, the utility will export each of the analyzers that are currently active in the capture to the specified folder. They will be named with the format N_Analyzer Name.csv, where N is the index of the capture and Analyzer Name is the user editable analyzer name in the software.

Examples

Just take 5 captures, each 0.1 seconds long, without saving anything.

python saleae_cli.py --capture-count 5 --capture-duration 0.1

Note: if python 2 and python 3 are installed, you may need to call python using python3

Take 24 captures, each 1 hour long, exporting the analyzers to an 'export' folder on the desktop.

Note that the destination folder must already exist before running the utility.

(Windows)

python saleae_cli.py --capture-count 24 --capture-duration 3600 --export-analyzers \Users\<Your User Name>\Desktop\export

(Linux or MacOS)

python saleae_cli.py --capture-count 24 --capture-duration 3600 --export-analyzers ~/Desktop/export

Take 100 captures, each 10 seconds long, saving all outputs to the same 'export' folder on the desktop

(Windows)

python saleae_cli.py --capture-count 100 --capture-duration 10 --save-captures \Users\<Your User Name>\Desktop\export --export-analyzers \Users\<Your User Name>\Desktop\export --export-data \Users\<Your User Name>\Desktop\export

(Linux or MacOS)

python saleae_cli.py --capture-count 3 --capture-duration 0.1 --save-captures ~/Desktop/export --export-analyzers ~/Desktop/export --export-data ~/Desktop/export
