plin-linux 0.0.3
The python-plin package is a Python wrapper for the chardev API provided by the PEAK LIN Linux Beta.
Requires Python: >=3.7

# Python PLIN library
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 Beta. The PEAK Linux beta driver is required to use this library and is available [here](https://forum.peak-system.com/viewtopic.php?t=5875).

## Installation
The `plin-linux` package is available on [PyPI](https://pypi.org/project/plin-linux/) and can be directly installed with `pip install plin-linux`.

## Examples
Runnable examples are located in the `examples/` directory.

### Master Example
```python
from plin.device import PLIN
from plin.enums import (PLINFrameChecksumType, PLINFrameDirection,
                        PLINFrameFlag, PLINMode)

# Initializes /dev/plin0 as a LIN master
master = PLIN(interface="/dev/plin0")

master.start(mode=PLINMode.MASTER, baudrate=19200)

# Get firmware version of the PEAK device
print(master.get_firmware_version())

# Get current status of the PEAK device
print(master.get_status())

# Add a publisher frame entry
master.set_frame_entry(id=0x22,
                       direction=PLINFrameDirection.PUBLISHER,
                       checksum_type=PLINFrameChecksumType.CLASSIC,
                       data=bytearray([0x01, 0x02, 0x03, 0x04]))

# Add a subscriber frame entry
master.set_frame_entry(id=0x23,
                       direction=PLINFrameDirection.SUBSCRIBER_AUTO_LEN,
                       checksum_type=PLINFrameChecksumType.CLASSIC)

# Get frame entry
print(master.get_frame_entry(id=0x22))

# Add unconditional slot to schedule 0
master.add_unconditional_schedule_slot(schedule=0, delay_ms=10, id=0x22)
master.add_unconditional_schedule_slot(schedule=0, delay_ms=10, id=0x23)

# Get schedule 0 slots
print(master.get_schedule_slots(0))

# Start schedule 0
master.start_schedule(0)

# Set ID filter
master.set_id_filter(bytearray([0xff] * 8))

# Read frames
while True:
    result = master.read()
    print(result)

```

### Slave Example
```python
from plin.device import PLIN
from plin.enums import PLINMode

# Initializes /dev/plin0 as a LIN slave
slave = PLIN(interface="/dev/plin0")

slave.start(mode=PLINMode.SLAVE, baudrate=19200)

# Set ID filter
slave.set_id_filter(bytearray([0xff] * 8))

# Read frames
while True:
    result = slave.read()
    print(result)

```

## Unit Tests
* Unit tests are located in the `unit_tests/` directory.
* Tests in `unit_tests/integration/` require a PEAK LIN device connected to run.
* Can be run with `pytest`.
