How to Control a device connected to miniLab 1008 using python?

[Parth]

Hello everyone,

I am trying to control a vacuum pump using the miniLab 1008. By control i mean, i have to turn it on and off. I am using mcculw API for that and trying to write a code that can do that. Till now i am unable to find it. I would be really thankful if some of you can help me with it.

Try the code below. It will set DIO0, DIO1, DIO2, and DIO3 low. Then, it will turn them on one at a time.

from __future__ import absolute_import, division, print_function
from builtins import *  # @UnusedWildImport
from time import sleep
from mcculw import ul
from mcculw.enums import DigitalIODirection, DigitalPortType, InterfaceType
from mcculw.device_info import DaqDeviceInfo

try:
    from console_examples_util import config_first_detected_device
except ImportError:
    from .console_examples_util import config_first_detected_device

def run_example():
    board_num = 0
    board_index = 0
    find_device = "miniLab-1008"

    board_num = -1
    ul.ignore_instacal()
    dev_list = ul.get_daq_device_inventory(InterfaceType.USB)
    if len(dev_list) > 0:
        for device in dev_list:
            if find_device in str(device):
                print(f"Found {str(device)} board number = {board_index}")
                print(f"Serial number: {device.unique_id}")
                print(f"Product type: {hex(device.product_id)}")
                board_num = board_index
                ul.create_daq_device(board_num, device)

            board_index = board_index + 1

        if board_num == -1:
            print(f"Device {find_device} not found")
            return
    else:
        print("No devices detected")
        return
    # **********End of Discovery************

    try:

        ul.d_config_port(board_num,  DigitalPortType.AUXPORT,  DigitalIODirection.OUT)
        ul.d_out(board_num, DigitalPortType.AUXPORT, 0)
        sleep(1.0)  

        for i in range(0, 4):
            bit_value = 2 ** i
            ul.d_bit_out(board_num, DigitalPortType.FIRSTPORTA, i, bit_value)
            sleep(1.0)  # example of delay
            print('Setting line', i, 'to', bit_value)

    except Exception as e:
        print('\n', e)
    finally:
        ul.release_daq_device(board_num)
