# Moku
A Python library for the command, control and monitoring of the [Liquid Instruments Moku:Go](http://www.liquidinstruments.com).

Official documentation for this library is available on the [Moku API documentation](https://apis.liquidinstruments.com/api/) page, and includes more information on getting started, tutorials and examples.

# Getting Started

### 1. Requirements
- [Python](https://www.python.org) >= **3.8** installed
- Your Moku connected to the same network as your computer
- Internet access

### 2. Install dependencies

#### mokucli
The `mokucli` utility is required for device discovery and data streaming. Download and install it from the [Moku Utilities](https://liquidinstruments.com/software/utilities/) page.

After installation, verify it works by listing Moku devices on your network:

    mokucli list

#### Python package
Open a command-line terminal and install the Moku Python library:

    pip install --upgrade moku

Or using uv (faster):

    uv pip install --upgrade moku

If you wish to build and train models for the Moku Neural Network instrument, install optional machine learning dependencies:

    pip install "moku[neuralnetwork]"
    # or with uv:
    uv pip install "moku[neuralnetwork]"

### 3. Using the moku CLI tool

The Moku package includes a command-line tool for downloading instrument definitions:

    moku download --os-ver <version>

This downloads the latest instrument definitions for the specified Moku OS version.

### 4. Start scripting
You are now ready to control your Moku:Go using Python! You can find a few example scripts in the **examples/** folder.
Here is a basic example of how to connect to a Moku:Go, deploy the Oscilloscope and fetch a single hi-res data trace. Open python and run the following code

```python
from moku.instruments import Oscilloscope

# Connect to your Moku by its ip Oscilloscope('192.168.###.###')
# or by its serial m = Oscilloscope(serial=123)
i = Oscilloscope('192.168.###.###', force_connect=False)

try:
    # Span from -1s to 1s i.e. trigger point centred
    i.set_timebase(-1, 1)

    # Get and print a single frame worth of data (time series
    # of voltage per channel)
    data = i.get_data()
    print(data['ch1'], data['ch2'], data['time'])
except Exception as e:
    print(f'Exception occurred: {e}')
finally:
    i.relinquish_ownership()
```

# Debug Logging

The Moku library includes built-in logging support for debugging connection issues and monitoring API calls. By default, the library does not produce any log output. To enable debug logging:

```python
import moku.logging

# Enable debug logging to stderr
moku.logging.enable_debug_logging()

# Your Moku code here - all operations will be logged
from moku.instruments import Oscilloscope
osc = Oscilloscope('192.168.###.###')

# Disable logging when done
moku.logging.disable_debug_logging()
```

For temporary debugging, use the context manager:

```python
import moku.logging

with moku.logging.LoggingContext():
    # Debug logging only enabled within this block
    osc = Oscilloscope('192.168.###.###')
    # ...
```

See `examples/logging_debug.py` for more detailed examples.

# Troubleshooting

#### moku: command not found
Ensure moku has been successfully installed in your Python distrubution by open a python shell and running

    import moku

No error indicates a successful install.

You may need to add python binaries to your PATH.  This varies with operating system and python version but as an example

    export PATH=$PATH:/home/user/.local/bin

#### ImportError: No Module named moku
Make sure you are running the version of Python you installed moku to.  Often a system will have multiple Python installations. Try substituting `pip` with `python -m pip` in the installation.
If you installed moku inside an Environment (i.e. via virtualenv or conda-env), ensure that Environment is activated. You can check that moku is installed in your currently running environment using

    (myenv)$ pip list
