An open-source, vendor-agnostic Python library for interfacing with test equipment.
Quickstart
from instro.daq.drivers.labjack import LabJackTSeriesDriver
# from instro.daq.drivers.ni import NIDAQDriver
from instro.daq import InstroDAQ
from instro.lib.publishers import FilePublisher
pub = FilePublisher(format="jsonl", directory="/tmp/instro/")
daq = InstroDAQ(
name = "myDAQ",
driver = LabJackTSeriesDriver(device_id="1234"),
publishers = [pub],
#driver = NIDAQDriver(device_id="Dev1") # swap drivers, same code
)
daq.open()
daq.configure_voltage_input(
physical_channel="AIN0", alias="ch_0", range_min=0, range_max=5
)
measurement = daq.read_analog() # written to `publishers`
print(pub.file_path.read_text())
