lightcon.fast_daq

Interface to the fast single-channel DAQ (E13-10023-02 or newer) DLL wrapper Example:

import lightcon.fast_daq

fdw = lightcon.fast_daq.FastDaqWrapper()

if fdw.is_connected():
    # sets missing trigger/clock timeout, after which TimeoutException is raised
    fdw.set_timeout(1000)

    # choose channel 'PFI0' for external clocking, 'internal' for internal clocking. Use 'rising' or 'falling' for active_edge
    fdw.configure_sample_clock(channel = 'PFI0', active_edge = 'rising')

    # choose channel 'PFI0' for external clocking, 'internal' for internal triggering
    fdw.configure_start_trigger(channel = 'internal')

    # sets external trigger delay for sampling to 100 ns
    fdw.set_external_trigger_delay(1000)

    # acquires n = 1000 samples as one-dimensional array
    data = fdw.get_daq_data(10)

    fdw.close()

lightcon.harpia_daq

Interface to the universal six-channel DAQ (PE04-005-04 or newer) DLL wrapper Example:

import lightcon.harpia_daq

# provide in ascending order to keep plot labels right
enabled_channels = ['AI0', 'AI1', 'AI3']
hdw = lightcon.harpia_daq.HarpiaDaqWrapper()

if hdw.is_connected:
    # sets missing trigger/clock timeout, after which TimeoutException is raised
    hdw.set_timeout(100)

    # enable analog input channels
    hdw.enable_channels(enabled_channels)

    # choose channel 'PFI0' - 'PFI5' for external clocking, 'internal' for internal clocking. Use 'rising' or 'falling' for active_edge
    hdw.configure_sample_clock(channel = 'internal', active_edge = 'falling')

    # choose channel 'PFI0' - 'PFI5' for external clocking, 'internal' for internal triggering
    hdw.configure_start_trigger(channel = 'PFI0')

    # acquires n=1000 samples and arranges to (m,n) two-dimensonal array, where m is number of enabled channels (in ascending order)
    data = hdw.get_daq_data(1000)    

lightcon.timing_controller

Timing controller API

Example:

import lightcon.timing_controller

tc = TimingController()
tc.connect()

if tc.connected:
    print ('Trigger source', 'EXTERNAL' if tc.get_trigger_source() == 1 else 'INTERNAL {:} Hz'.format(tc.get_frequency()))
    print ('\n'.join(['Channel {:}, delay {:} ns, {:}'.format(i, tc.get_delay(i), 'ENABLED' if tc.get_enabled(i)==1 else 'DISABLED') for i in [1,2,3,4]]))

Output:

Connected to timer_stopwatch on COM12 (E131001401, firmware version: 1.0.1)
Trigger source INTERNAL 1750 Hz
Channel 1, delay 0 ns, DISABLED
Channel 2, delay 0 ns, DISABLED
Channel 3, delay 0 ns, DISABLED
Channel 4, delay 0 ns, DISABLED
