Installation

Install from source:

Using evic-usb requires cython-hidapi. You can install it using pip:

$ pip install hidapi

Building cython-hidapi requires libusb headers and cython. On Arch Linux they can be obtained from the repositories by installing packages libusb and cython. Debian based distributions will have packages libusb-1.0-0-dev and cython.

On Windows you will also need the correct compiler for your Python version. See this page for more information on setting up the compiler.

Building python-evic:

$ git clone git://github.com/Ban3/python-evic.git
$ cd python-evic
$ python setup.py install

Allowing non-root access to the device

The file udev/99-nuvoton-hid.rules contains an example set of rules for setting the device permissions to 0666. Copy the file to the directory /etc/udev/rules.d/ to use it.

Autosync time when device connected

The file scripts/evic-usb-rtc-sync.service + udev/99-nuvoton-hid.rules is a example of how to auto sync time
