Unexpected keyword argument 'data'

[JorgeBarredo14]

When connecting to a Lecroy oscilloscope, line 130 traceFile.append(trsfile.Trace(trsfile.SampleCoding.BYTE, channel_out, data=data_output)) outputs the following error:

ERROR: init() got an unexpected keyword argument 'data'

The 'data' argument of the Trace constructor has been deprecated since version 2.0.0. It is recommended that you use a TraceParameterMap instead. A TraceParametersMap has replaced the data field because the map contains meta-data on the type and purpose of the data in the trace.
If your data contains solely output data, you could use a TraceParameterMap like this:

trace_params = trsfile.TraceParameterMap()
trace_params.add_parameters("OUTPUT", data_output)
traceFile.append(trsfile.Trace(trsfile.SampleCoding.BYTE, channel_out, parameters=trace_params))

As an additional note: Pull request #38, which is currently in review, will add a replacement of the deprecated 'data' argument named 'raw_data'. This will be part of the next version of this library.

Hi Tom! The code works well now, but trace_params = trsfile.TraceParameterMap() provides the error module 'trsfile' has no attribute 'TraceParameterMap'. I have tried to solve it by linking the method TraceParameterMap once imported the library trsfile, but it does not solve the issue.

My apologies, I thought that that map was included in the imports done with import trsfile, but it is not.
You can add the import from trsfile.parametermap import TraceParameterMap and then use ` trace_params = TraceParameterMap()'
