pyadvantech

Interact with the Advantech USB-4718

Install the module via:
```
pip install pyadvantech
```
You might need to add the libusb.dll to your Path.
Plug in the USB-4718 into your machine and install a WINUSB driver as its driver.
```
import pyadvantech.pyadvantech as pya

device = pya.setup(vendor_id=None,device_id=None)
pya.prepare_read()
print(pya.read(device))
```
The vendor id and device id can be manually set but if left unspecified will default to the known tested values.
Prepare read tells the device that it should now read the thermocouple. This call might not be necessary but it is a good Idea to call it as it moves the device out of a setup stage into the read stage.

Changes to the Value Ranges of the device can be made with:

import pyadvantech.pyadvantech as pya

device = pya.setup()
pya.set_channel_range(device,values=[0x0e,0x0b,0x0b,0x0b,0x0b,0x0b,0x0b,0x0b])

If values is left as none it will reset the device to the 0-100mv range.

Multiple values can be selected and saved with:

import pyadvantech.pyadvantech as pya
device = pya.setup()
pya.read_and_save(device,channel=1,length=1000,update=0.1,file_name="test.csv")

Variable Name	Description	Default Value
device	The Device handle	required
channel	The channel to be saved and stored	required [0:7]
length	Number of measurements to be taken	1000
update	The update time in sec	0.1
file_name	The file name must end in .csv	format "%Y_%m_%d_%H_%M_%S".csv

An Experimental plotting tool is also provided:

import pyadvantech.pyadvantech as pya
device = pya.setup()
pya.plot_out(device,channel=1,x_name=None,y_name=None,x_range=60,update=None,acquisition_len=None)

Variable Name	Description	Default Value
device	The Device handle	required
channel	The channel to be saved and stored	required [0:7]
x_name	X axis label	Time in update sec intervals
y_name	Y axis label	Output of USB device
x_range	Range of x axis, if left None will just add new values continuously	None
update	The update time in sec	0.1
acquisition_len	Number of measurements to be taken	500 can be set to "inf"
