ABS SCPI Python Library (absscpi)

Python library for SCPI control of the Bloomy Controls ABS.

Features

  • TCP, UDP, RS-485, and UDP multicast
  • Supports Windows and Linux
  • Implements all SCPI commands and queries supported by the ABS
  • Automatic device discovery over UDP multicast and RS-485
  • Implemented as a wrapper around the C/C++ library for a consistent interface regardless of the language

Installation

See docs/installation.rst for installation instructions.

Example usage

# import the library
import absscpi
from time import sleep

with ScpiClient() as client:
    # open a UDP socket
    client.open_udp("192.168.1.100")

    # get general device information
    id = client.get_device_id()
    ident = client.get_device_info()
    print(f"Device ID: {id}")
    print(f"Part numer: {ident.get_part_number()}")
    print(f"Serial number: {ident.get_serial_number()}")
    print(f"FW version: {ident.get_version()}")

    # command cell 1 to 1.4V
    client.set_cell_voltage(0, 1.4)
    client.set_cell_sourcing(0, 5.0)
    client.set_cell_sinking(0, 5.0)
    client.enable_cell(0, True)

    sleep(0.05)

    # measure cell 1's voltage
    v = client.measure_cell_voltage(0)
    print(f"Cell 1 voltage: {v}")

    client.enable_cell(0, False)
