This Python module provides Python bindings for the official C/C++ Linkam SDK. It enables monitoring and control of various instruments provided by Linkam Scientific. The library can optionally be used with the [pint](https://pint.readthedocs.io/en/stable/) package to handle unit conversion.
### Background
We use a Linkam HFS600E-PB4 stage with T96 controller for gas sensing experiments in the [Swinburne](https://swin.edu.au) Sensor Technology Lab. This library has been parted out from our custom developed experiment software for general use. If you find the package useful we'd love to hear about your projects!
## Installation
Note that the Linkam SDK binary files (`LinkamSDK.dll` or `libLinkamSDK.so`) and the required license file (typically `Linkam.lsk`) are **not** distributed as part of this module.
By default, the module will look for the Linkam SDK binary using the `$PATH` environment variable via the `ctypes` module and will automatically append the module directory before searching.
1. Place `LinkamSDK.dll` (debug or release) and `Linkam.lsk` files inside the `pylinkam` **module folder** (the one that contains `__init__.py`). Alternately, at runtime you can specify a binary name (remove the `.dll` extension on Windows) and path to access these files.
2. Run `demo.py` to check for any connection/path issues. This will set the stage temperature to 25°C temporarily.
### Getting Module Path and Troubleshooting
Running the following in a Python console/environment should tell you where the place the `LinkamSDK.dll` (or Linux equivilent) and `Linkam.lsk` files.
```python
import pylinkam
print(pylinkam.__file__)
```
The SDK also generates log files in this directory by default, this is the first place to check when diagnosing issues. If you see license errors (quite common even in legimate installations) you'll need to contact your equipment supplier or Linkam support.
## Usage
### Context Manager Example
Initialise the SDK by creating an instance of `pylinkam.sdk.SDKWrapper` providing optional paths for SDK binary files and the license file. Once initialised, use the `connect()` method to create a context manager for the connection to a device.
```python
from pylinkam import interface, sdk
with sdk.SDKWrapper() as wrapper:
with wrapper.connect() as connection:
print(f"Name: {connection.get_controller_name()}")
temperature = connection.get_value(interface.StageValueType.HEATER1_TEMP)
connection.set_value(interface.StageValueType.HEATER_SETPOINT, 30)
```
### Manual Example
You can also use the classes directly without context managers, but you'll have to close connections manually to avoid memory leaks.
```python
from pylinkam import interface, sdk
connection = sdk.SDKWrapper().connect_usb()
print(f"Name: {connection.get_controller_name()}")
temperature = connection.get_value(interface.StageValueType.HEATER1_TEMP)
connection.set_value(interface.StageValueType.HEATER_SETPOINT, 30)
connection.close()
```
## Python Versions
This library requires a minimum of Python 3.6 to function. Newer versions should be compatible.
## CPU Architecture
This library has only been tested on 64-bit x86 processors.
## Tested Devices
This library has been developed for the following Linkam instruments/addons, a check indicates that functionality has been verified on working hardware:
- [x] T96 System Controller (via USB)
- [ ] T96 System Controller (via RS-232, might work :shrug:)
- [x] HFS600E-PB4 Probe Stage (all stages should be supported)
- [x] RH95 Humidity Controller
- [ ] LNP96 Cooling Option (should work)
Note that connecting multiple devices to a single host is untested, though the connect functions per the Linkam API *can* accept a serial number.
## Tested API Versions and Platforms
- [x] `v3.0.5.5` on Windows 10
- [x] `v3.0.15.35` on Windows 10
- [x] `v3.0.19.12` on Windows 10
In theory the SDK binary files for Linux should have identical mappings, but this hasn't been tested. Versions `< 1.2.3` used `WinDLL` to load the Linkam SDK binary, however more recent versions will automatically detect the platform and use `CDLL` when not on Windows. We don't have hardware connected to a Linux machine to test, so please report any issues.
