Yes, I did. Honestly I don't understand it. I looked for winpdb at
http://www.winpdb.org/ and found the web site down. Searching for winpdb
I found https://github.com/bluebird75/winpdb.

So added these lines
import rpdb2
rpdb2.start_embedded_debugger("pd")
This results in an error message when I start sigrok-cli:
--
C:\Data>sigrok-cli -P i2c,exc80h -i r2.sr
srd: ImportError: Failed to create exc80h instance: No module named 'rpdb2'
srd: Traceback (most recent call last):
File "C:\ProgramData\libsigrokdecode\decoders\exc80h\pd.py", line 56,
in __init__
import rpdb2
ImportError: No module named 'rpdb2'
Failed to instantiate protocol decoder exc80h.
--
So I think, I need to add rpdb2 to the sigrok's python library. ProcMon
(somthing similar to strace) tells me that sigrok-cli reads python from
C:\Program Files (x86)\sigrok-cli\python34.dll. Further the file
python34.zip is read. This file includes a lot of .PY files that would
resists in the lib directory of a normal python installation.
How can I make rpdb2 available to the python module that runs the
decoder in sigrok-cli (or PulseView)?

Shouldn't I use th python that comes with sigrok?

Well that is the actual use case. But how solve I the problems mentioned
above on a Linux environment?
Well, unfortunately my questions still remain:
- How can I setup a debugger (I hope WinPDB, pdb would also be okay) on
my Windows 10 PC?
- How can I attach the debugger to the running PulseView process, or can
I start the program from the debugger?
Best regards,
Helge
