/*
|
|
* The CSV input module has the following options:
|
|
*
|
|
* single-column: Specifies the column number which stores the sample data for
|
|
* single column mode and enables single column mode. Multi
|
|
* column mode is used if this parameter is omitted.
|
|
*
|
|
* numchannels: Specifies the number of channels to use. In multi column mode
|
|
* the number of channels are the number of columns and in single
|
|
* column mode the number of bits (LSB first) beginning at
|
|
* 'first-channel'.
|
|
*
|
|
* delimiter: Specifies the delimiter for columns. Must be at least one
|
|
* character. Comma is used as default delimiter.
|
|
*
|
|
* format: Specifies the format of the sample data in single column mode.
|
|
* Available formats are: 'bin', 'hex' and 'oct'. The binary
|
|
* format is used by default. This option has no effect in multi
|
|
* column mode.
|
|
*
|
|
* comment: Specifies the prefix character(s) for comments. No prefix
|
|
* characters are used by default which disables removing of
|
|
* comments.
|
|
*
|
|
* samplerate: Samplerate which the sample data was captured with. Default
|
|
* value is 0.
|
|
*
|
|
* first-channel: Column number of the first channel in multi column mode and
|
|
* position of the bit for the first channel in single column mode.
|
|
* Default value is 0.
|
|
*
|
|
* header: Determines if the first line should be treated as header
|
|
* and used for channel names in multi column mode. Empty header
|
|
* names will be replaced by the channel number. If enabled in
|
|
* single column mode the first line will be skipped. Usage of
|
|
* header is disabled by default.
|
|
*
|
|
* startline: Line number to start processing sample data. Must be greater
|
|
* than 0. The default line number to start processing is 1.
