22- The [ CsvWriter] ( xref:Bonsai.IO.CsvWriter ) operator writes the ` Clock ` , ` DigitalInputs ` , and ` Buttons ` members from the
23- ` DigitalInputDataFrame ` to a file with the following name format: ` digital-input_<filecount>.csv ` . Because ` CsvWriter `
24- is a _ sink_ operator, its output sequence is equivalent to its input sequence. In other words, its output is equivalent
25- to ` DigitalInput ` 's output. Therefore, it's possible to use
26- [ MemberSelector] ( xref:Bonsai.Expressions.MemberSelectorBuilder ) operators on the ` CsvWriter ` to select members from
27- ` DigitalInputDataFrame ` . This is most easily performed by clicking the relevant members that appear by hovering over the
28- "Output" option that appears in the context menu that appears after right-clicking the ` CsvWriter ` node. The members
29- selected in the workflow, < xref:OpenEphys.Onix1.DigitalPortState > and < xref:OpenEphys.Onix1.BreakoutButtonState > , are
30- enumerators with values that correspond to bit positions of the breakout board's digital ports. When ` DigitalPortState `
31- or ` OpenEphys.Onix1.BreakoutButtonState ` is connected to a ` HasFlags ` operator, the names that appear in the
32- ` HasFlags ` 's ` Value ` property's dropdown menu correspond to bit positions in the respective digital input port. In this
33- workflow, the top ` HasFlags ` operator checks if ` Triangle ` or ` X ` are ` True ` .
22+ ` Clock ` , ` DigitalInputs ` , and ` Buttons ` are all members of ` DigitalInputDataFrame ` which are each
23+ selected by a [ MemberSelector] ( xref:Bonsai.Expressions.MemberSelectorBuilder ) operator. They contain
24+ the < xref:OpenEphys.Onix1.ContextTask.AcquisitionClockHz > -based sample times, digital port status,
25+ and buttons' status, respectively. The [ MatrixWriter] ( xref:Bonsai.Dsp.MatrixWriter ) operators save
26+ the selected members to files with the following format: ` digital-clock_<filecount>.raw ` , and
27+ ` digital-pins_<filecount>.raw ` , and ` digital-buttons_<filecount>.raw ` , respectively.

29+ Because ` MatrixWriter ` is a _ sink_ operator, its output sequence is equivalent to its input
30+ sequence. For example, the output of the ` MatrixWriter ` connected to ` Button ` is equivalent to
31+ ` Button ` 's output. Therefore, it's possible to process digital data by branching directly off the
32+ ` MatrixWriter ` operators. The selected ` DigitalInputs ` and ` Buttons ` members are both enumerator
33+ types: < xref:OpenEphys.Onix1.DigitalPortState > and < xref:OpenEphys.Onix1.BreakoutButtonState > ,
34+ respectively. Enumerators assign names to values. When ` DigitalPortState ` or ` BreakoutButtonState `
35+ is connected to a ` HasFlags ` operator, these names appear in the ` HasFlags ` 's ` Value ` property's
36+ dropdown menu. In this case, the values that these names represent correspond to bit positions of
37+ the breakout board's digital ports. In this workflow, the top ` HasFlags ` operator checks if ` Pin0 `
38+ is ` True ` , and the bottom ` HasFlags ` operator checks if ` Triangle ` or ` X ` are ` True ` .
