# Sensapex SDK

This python library wraps the C SDK provided by Sensapex's umsdk. It provides general access to the
functions present therein, as well as a device-based abstraction.

### Installation

`pip install sensapex`

This library comes packaged
with [the latest umsdk library](http://dist.sensapex.com/misc/um-sdk/latest/) for windows. All other
versions can be downloaded and/or compiled separately and configured with `UMP.set_library_path`.

### Usage

```python
from sensapex import UMP

ump = UMP.get_ump()
dev_ids = ump.list_devices()

stage = ump.get_device(20)
stage.calibrate_zero_position()

manipulator = ump.get_device(4)
manipulator.goto_pos((2500.0412, 6810.0003, 15830.1419), speed=200)

pressure = ump.get_device(30)
pressure.set_pressure(1, 2.3e-4)
```

Also included are some simple test scripts. The following will report on all devices present:

```bash
python -m sensapex.test
```

Or for a more involved test of your hardware as it moves around randomly,
install [pyqtgraph](https://pyqtgraph.org) in your environment and use e.g.:

```bash
python -m sensapex.accuracy_test <device_id>
```

Where `<device_id>` should be replaced with the numerical ID of your device, as shown by `python -m sensapex.test`.


#### Debug

You can turn on debugging to produce detailed logs and network packet captures. First,
install [Wireshark](https://www.wireshark.org/download.html) (or for linux, use your package manager
to get the `pcaputils` package). Make sure the user account you use has permission to run
the `dumpcap` program. Next, install the psutil python package:

```bash
pip install psutil
```

Once those are installed, you can turn on the debug logging for your SDK wrapper:

```python
from sensapex import UMP

UMP.set_debug_mode(True)
ump = UMP.get_ump()
```

This will create a directory, `sensapex-debug/` in the current working directory, populated with a
log file and a pcap file. Repeated initializations of the debug mode will create addition pcap files
and append to the log file. These can be sent to
[Sensapex](mailto:support@sensapex.com) along with any relevant details, such as:

* A description of errant behavior
* The color of each of the relevant device lights
* A picture of the touchscreen state
* Steps to reproduce and how consistently it occurs
