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.

[DAQman]

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)

if __name__ == '__main__':
    run_example()

For my case the Connected ports are that to CH01, CH02 and GND. There are also further connection made to the ME-UBRE device (Which I think is using the top Digital I/O connector). How do you think this changes the code, I require. Thank you.
