Digital Multimeter provides both a CLI and Python API interface to receive data
from a variety of digital multimeters.
See the list of supported multimeters [here](https://digital-multimeter.readthedocs.io/en/latest/supported-multimeters/).
## Features
* Command line and Python module interface to digital multimeters
* Continuous live data readings (using `--count 0`)
* Output in **json** or **csv** formats
* Output to console or file, allowing other tools to pickup and use the data
* Configuration via config-file or environment-variables
* Easy to expand for new digital-multimeter protocols
* Easy installation using PyPI `pip`
* Documentation and examples at [digital-multimeter.readthedocs.io](https://digital-multimeter.readthedocs.io)
## Installation
```shell
user@computer:~$ pip install [--upgrade] digital-multimeter
```
## CLI Usage Example
Continuously read the digital-multimeter and pipe the JSON output through `jq` to
make the JSON output look prettier.
```shell
user@computer:~$ dmm read --connect /dev/ttyUSB0 --count 0 | jq .
