This library provides a Python interface for interacting with PEAK devices such as the PCAN-USB Pro and PLIN-USB on Linux using the chardev API provided by the PEAK LIN Linux Driver. The PEAK LIN Linux driver is required to use this library and is available here.
The plin-linux package is available on PyPI and can be directly installed with pip install plin-linux.
Runnable examples are located in the examples/ directory.
