NiDAQMX关闭所有创建的任务

Question

I would like to close all the previously created tasks in the nidaqmx-python module.

How can I do this?

In example, I have a number of previously opened tasks:

for i in range(10):
    nidaqmx.Task()

which I did not close. However, I want to close them now.

Answer 1

According to the source, you'll have to do something like the following:

tasks = []
for i in range(10):
    tasks.append(nidaqmx.Task())

# Some code ...

for task in tasks:
    task.close() 

See https://github.com/ni/nidaqmx-python/blob/master/nidaqmx/task.py#L448

Answer 2

Have you tried using a reset_device() on the device you are using? It should make all tasks associated with the device able to be started again.

edit: though it cleared the tasks, but it only aborts them.
