Hi Jim, I was able to get the MFM decoder ( http://www.sardis-technologies.com/ufdr/pulseview.htm) working on PulseView version 0.4.2 after a quick edit to update the decoder.
PulseView logged an error message while loading the MFM decoder that says it has no reset() method. So the decoder probably predates a change in libsigrokdecode where decoders are required to have a reset() method. https://sigrok.org/gitweb/?p=libsigrokdecode.git;a=commit;h=10aeb8ea8b183394cebc0033f048f49f4262b57d The quick fix is to rename the decoder's __init__ method to reset, and have __init__ call reset. It is only a few lines change which you can do yourself, but I also attached a file with the change already done. Rename and replace the pd.py file in the mfm decoder directory. It worked on the MFM sample data included with the decoder SampleMFMdataAnaDig.sr. For reference, PulseView's log output is in Settings (screwdriver and wrench icon near the top left), then Logging. It showed the following error message for the MFM decoder: AttributeError: Protocol decoder mfm Decoder class has no reset() method: type object 'Decoder' has no attribute 'reset' srd: Failed to load decoder mfm: no 'reset()' method On Mon, Mar 13, 2023 at 6:35 PM Jim Grant <jgrant...@gmail.com> wrote: > I am using PulseView to troubleshoot old floppy disk technology.
