pyccapt.control.devices_test.tdc_surface_concept_t_2 module

class pyccapt.control.devices_test.tdc_surface_concept_t_2.BufDataCB4(lib, dev_desc, data_field_selection=116, max_buffered_data_len=500000, dld_events=True)

Bases: buffered_data_callbacks_pipe

Parameters:

• lib (scTDClib) – a scTDClib object.

• dev_desc (int) – device descriptor as returned by sc_tdc_init_inifile(…).

• data_field_selection (int, optional) – a ‘bitwise or’ combination of SC_DATA_FIELD_xyz constants. The default is SC_DATA_FIELD_TIME.

• max_buffered_data_len (int, optional) – The number of events that are buffered before invoking the on_data callback. Less events can also be received in the on_data callback, when the user chooses to return True from the on_end_of_meas callback. The default is (1<<16).

• dld_events (bool, optional) – if True, receive DLD events. If False, receive TDC events. Depending on the configuration in the tdc_gpx3.ini file, only one type of events may be available. The default is True.

Return type:

None.

on_data(d)

Override this method to process the data.

Parameters:

data (dict) –

A dictionary containing several numpy arrays. The selection of arrays depends on the data_field_selection value used during initialization of the class. The key names in this dictionary, that are always present, are:

event_index, data_len

Keywords related to regular event data are:

subdevice, channel, start_counter, time_tag, dif1, dif2, time, master_rst_counter, adc, signal1bit

Keywords related to indexing arrays are:

som_indices, ms_indices. These contain event indices where the start of a measurement happened, or a millisecond count up happened.

Return type:

None.

on_end_of_meas()

Override this method to trigger actions at the end of the measurement. Do not call methods that start the next measurement from this callback. This cannot succeed. Use a signalling mechanism into your main thread, instead.

Returns:

True indicates that the pipe should transfer the remaining buffered events immediately after returning from this callback. False indicates that the pipe may continue buffering the next measurements until the max_buffered_data_len threshold is reached.

Return type:

bool
