mchplnet 0.5.1

Python implementation of Microchip LNet protocol

mchplnet

• mchplnet is the Python implementation of the LNet protocol.
• It implements multiple LNet services to communicate to embedded systems/microcontrollers.
• Currently only pyserial interface is supported.
• It is recommended to use the pyx2cscope package, which offers a higher-level interface.

Getting Started

1. Navigate to the Examples directory in the mchplnet project to explore the available examples or create a new .py file based on your requirements.
2. Import the necessary classes:

from mchplnet.interfaces.factory import InterfaceFactory
from mchplnet.interfaces.factory import InterfaceType as IType
from mchplnet.lnet import LNet

3. Create an interface according to your requirements and initialize the LNet with the interface:

Option A: Auto-detection (Recommended for single device)

# Automatically detect the COM port with an LNet device
interface = InterfaceFactory.get_interface(IType.SERIAL, port="AUTO", baudrate=115200)
l_net = LNet(interface)
print(f"Connected to {interface.com_port}")

Option B: Manual port specification

# Specify the COM port explicitly
interface = InterfaceFactory.get_interface(IType.SERIAL, port="COM8", baudrate=115200)
l_net = LNet(interface)

4. Use the appropriate functions, such as get_ram, to interact with variables by specifying their address and size:

var_address = 0x00000000
var_size = 4 
var_value = l_net.get_ram(var_address, var_size) 
logging.debug(var_value)

5. To modify the value of a variable, use the put_ram function:

var_newValue = 500
l_net.put_ram(var_address, var_size, var_newValue)

Development Setup

To set up the development environment:

1. Clone the repository:

   git clone https://github.com/X2Cscope/mchplnet.git
   cd mchplnet
   

2. Install development dependencies:

   pip install -e ".[dev,docs,build]"
   

3. Install pre-commit hooks:

   pre-commit install
   

4. The pre-commit hook will now run automatically on each commit to ensure code quality and version consistency.

Publishing a release

Package releases are handled by GitHub Actions as part of the maintainer release workflow.
