Python daqmx client workflow question

[rdecarreau]

My workflow for using Python as a client is to copy the proto file from this repo into my own and then generate that into nidaqmx_pb2. My issue with that is I already have a proto codegen process for our client/server code and these protos don't make a ton of sense to add in with our code.
I think I need to create a new place in my codebase for the protofiles, and create a slightly modified codegen process. That feels a little heavy. Is there a released python client for the autogenerated python code? That would be much simpler and I can't think of why that would not be a good idea.

Ping on this. Not sure who might know.

@rdecarreau, I apologize for the extremely delayed response.

The nidaqmx Python package supports proxying DAQmx API calls to NI gRPC Device Server. To use this feature, specify grpc_options when you construct the nidaqmx.Task object.

Example:

import grpc
import nidaqmx
from nidaqmx.constants import AcquisitionType, READ_ALL_AVAILABLE

with grpc.insecure_channel("localhost:31763") as channel:
    with nidaqmx.Task(grpc_options=nidaqmx.GrpcSessionOptions(channel, "")) as task:
        task.ai_channels.add_ai_voltage_chan("Dev1/ai0")
        task.timing.cfg_samp_clk_timing(1000.0, sample_mode=AcquisitionType.FINITE, samps_per_chan=50)

        data = task.read(READ_ALL_AVAILABLE)
        print("Acquired data: [" + ", ".join(f"{value:f}" for value in data) + "]")
