Moku offers APIs for Python, MATLAB, and LabVIEW for seamless automation and integration into your workflow. Starting with MokuOS 4.0, the use of APIs requires the command line utility, mokucli.
What is mokucli?
Mokucli allows users to access and manage Moku hardware through their command terminal. Functionalities include bitstream downloads, device discovery, data streaming, among others. More information on how to use mokucli can be found on this documentation page.
With the release of MokuOS 4.0, mokucli is required for API integration.
How do I setup mokucli?
Mokucli can be downloaded from the download links at the bottom of the Utilities page.
Once downloaded, follow the instructions for installation:
NOTE: If needed, type mokucli --help to list possible functionalities, check the mokucli version, among other tools.
Getting the APIs up and running:
Run the following command in your terminal: mokucli instrument download 4.0.1 to download the instrument bitstreams. Replace 4.0.1 with the current most up-to-date firmware release.
If you have not yet used APIs prior to updating to 4.0, please follow the instructions in this Getting Started Guide on how to get the APIs installed.
Below are the steps to update the APIs with MokuOS 4.0 and above, after mokucli has been installed:
Python:
- Open your command terminal and update the Python client package by running:
pip install --upgrade moku
MATLAB:
- Open MATLAB after the new mokucli has installed.
- Go to the “Home” tab and select “Add-ons” to open the sub-menu. Click “Manage Add-Ons”.
- Look for the moku-MATLAB add-on listed with an available update. NOTE: If you do not see an update option, you likely need to restart MATLAB and try again.
- Click “Update” and restart MATLAB. The API will be ready for use.
Labview:
Currently, Labview is not supported for MokuOS 4.0.1. This section will be updated as soon as it is added.
