Canvect v0.1.5 Release Notes

Canvect is a Python package designed for sending and managing CAN (Controller Area Network) messages

Overiew

Updated version adds advantage and seamless integration of Pcan and Socketcan as interfaces related to Actuation control of vechile. It provides a simple yet flexible API for creating and dispatching CAN messages, making it ideal for applications in automotive and industrial systems where CAN communication is essential.

New Features

1. Dynamic Parameter Input: Users can now input dynamic parameters for the following

• arbitration_id: Specify the CAN ID as a hexadecimal value.
• seventh_byte: Set the seventh byte for the CAN message (value between 0-15).
• channel: Define the CAN channel (e.g., 'PCAN_USBBUS2').
• interface: Choose the CAN interface (e.g., 'pcan').
• bitrate: Set the bitrate for the CAN bus communication (e.g., 500000).

This enhancement allows users to customize their CAN message sending directly from input prompts, making the package more versatile and user-friendly.

Installation

pip install canvect==0.1.6

Sample Usage Examples

1. You can now easily modify parameters like arbitration_id, bitrate, and channel to suit your specific needs:ds

from Canvect import continuous_acceleration_send

continuous_acceleration_send(
    arbitration_id=int(input("Enter arbitration ID (hex): "), 16),  # Custom CAN ID
    seventh_byte=int(input("Enter the value for the seventh byte (0-15): ")),  # Seventh byte
    channel=input("Enter CAN channel (e.g., 'PCAN_USBBUS2'): "),  # Custom CAN channel
    interface=input("Enter CAN interface (e.g., 'pcan'): "),  # Custom interface
    bitrate=int(input("Enter bitrate (e.g., 500000): "))  # Custom bitrate
)

Example with RingBuffer

from Canvect import RingBuffer

# Create a RingBuffer with a capacity of 5 items
buffer = RingBuffer(capacity=5)

# Append items to the buffer
for i in range(10):
    buffer.append(f"message_{i}")
    print(f"Buffer after appending message_{i}: {buffer}")

# Access items by index
for i in range(len(buffer)):
    print(f"Item at index {i}: {buffer[i]}")

1. The buffer can hold up to 5 items. Once it reaches the maximum capacity, new items will overwrite the oldest ones.

2. You can access items using their index. If you try to access an index that is out of range, an IndexError will be raised.

Note: Here refers to above example

Terminal SPecific Sample1 Code to Send..

    channel = input("Enter CAN channel (e.g., 'PCAN_USBBUS2'): ")
    interface = input("Enter CAN interface (e.g., 'pcan'): ")
    bitrate = int(input("Enter bitrate (e.g., 500000): "))
    buffer_capacity = int(input("Enter ring buffer capacity: "))
