harp-serial

Serial transport for harp-device. Provides SerialTransport and the open_device factory, which pairs a device module or a Device class with a serial port. This is the package that pulls in pyserial.

Usage

Like the builtin open, the returned device is connected and ready. Use it in a with block for guaranteed cleanup:

from harp import serial
from harp.device import behavior, core

# Use "COMx" on Windows, "/dev/ttyUSBx" on Linux.
with serial.open_device(behavior, port="COM3") as device:
    print(device.read(core.WhoAmI).payload)         # a core register
    print(device.read(behavior.AnalogData).payload) # a device register

Passing a device module validates the device identity on open. Pass a Device subclass instead to preserve its own type, or omit the argument entirely for schema-free access, which skips the identity check.

harp-serial is released as open source under the MIT license. Bug reports and contributions are welcome at the GitHub repository.
