Hello, I am a nidaq beginner, so this question may have a very simple answer. I am using a PCIe-6321, and trying to use the hardware timing feature. I am controlling it with python (nidaqmx).
When I run the following code (snippet from the ao_voltage_hw_timed.py example), I get an error:
"""Example of AO voltage hw operation."""
import nidaqmx
with nidaqmx.Task() as task:
task.ao_channels.add_ao_voltage_chan("Dev1/ao0")
task.timing.cfg_samp_clk_timing(1000)
print("1 Channel N Samples Write: ")
print(task.write([1.1, 2.2, 3.3, 4.4, 5.5], auto_start=True))
task.wait_until_done()
task.stop()
error message:
1 Channel N Samples Write:
Traceback (most recent call last):

nidaqmx.errors.DaqWriteError: A hardware failure has occurred. The operation could not be completed as specified.
Task Name: _unnamedTask<0>
Status Code: -50152
When I comment out the cfg_samp_clk_timing line (i.e. not using hardware timing), I do not get the error message:
1 Channel N Samples Write:
5
How can I troubleshoot this?
