prerequisites

multidaq depends only on numpy.
Needed binaries to access the hardware are included (DLL)

linux: Two important points: you need rights to access the devices and a installed SDL2 lib.
There are at least 3 ways to get the rights. Method 3 is the safest.

1. Be administrator or open python with sudo, you have all rights.
2. Add yoursel to dialout group: Open a terminal and enter following command with your username.

sudo usermod -a -G dialout <your_username>

3. Use udev: First download the file from github and copy to a system location:

sudo cp 50-biovision-devices.rules /etc/udev/rules.d/50-biovision-devices.rules

SDL2 is widely used and probaly installed on your PC. If not, install at least:

sudo apt-get install libsdl2-2.0-0 libsdl2-ttf-2.0-0 libsdl2-image-2.0-0

.

getting started

open a command terminal:

pip install multidaq

in python console or script you may test the installation with:

import multidaq
dev = multidaq.multiDaq()
print(dev.listDevices())

output will be a list of strings with informations of devices on the bus. If no device is present you will get an empty list.
An exception should not occur and would be an error.
