Combining Kicad and Skidl part libraries

[justinbalexander]

I am not sure what I am doing wrong.

My default tool is KICAD and my search paths are like so:

lib_search_paths[KICAD].append('../library/snapEDA')
lib_search_paths[SKIDL].append('../library/skidl_lib')
lib_search_paths[KICAD].append('/usr/share/kicad/library')

in the SKIDL search path the part definition is in a file called gamete_lib.py.

The error I get is:

WARNING: Could not load KiCad schematic library "gamete", falling back to backup library.
Traceback (most recent call last):
  File "/home/alexander/.local/lib/python3.6/site-packages/skidl/tools/kicad.py", line 60, in _load_sch_lib_
    f, _ = find_and_open_file(filename, lib_search_paths_, lib_suffixes[KICAD])
  File "/home/alexander/.local/lib/python3.6/site-packages/skidl/utilities.py", line 290, in find_and_open_file

    raise exc_class(message)

During handling of the above exception, another exception occurred:

  File "gamete.py", line 123, in <module>
    footprint='Package_TO_SOT_SMD:SOT-353_SC-70-5_HandSoldering',

    raise e

    load_func(filename, skidl.lib_search_paths[tool])
  File "/home/alexander/.local/lib/python3.6/site-packages/skidl/tools/kicad.py", line 64, in _load_sch_lib_
    filename, str(e)
FileNotFoundError: Unable to open KiCad Schematic Library File gamete (Can't open file: gamete.
)

The error looks like it is searching for a KICAD libary file. Do I have to change the default tool every time I search for a part that is in the other supported type? Skidl found previous Kicad parts that I instantiated.

Trying my own suggestion didn't work either.

I made the repo public and pushed it in it's failing state. I don't understand why the library isn't being found.

To build you have to cd into this directory: https://github.com/vegecode/Gamete/tree/master/pcb/skidl and use command python3 gamete.py

Can someone help me understand why i am getting the above error about the file not being found?

I tried your code and found these errors:

1. Instead of calling your library gamete_lib.py, you'll need to call it gamete_sklib.py.

2. When you access the library, you'll have to do it like this:

   led_driver = Part(
       'gamete',
       'TPS61169',
       tool=SKIDL,
       manu='Texas Instruments',
       part_no='TPS61169DCKR',
       footprint='Package_TO_SOT_SMD:SOT-353_SC-70-5_HandSoldering',
   )

   or like this:

led_driver = Part(
        'gamete_sklib.py',
        'TPS61169',
        tool=SKIDL,
        manu='Texas Instruments',
        part_no='TPS61169DCKR',
        footprint='Package_TO_SOT_SMD:SOT-353_SC-70-5_HandSoldering',
)

3. In gamete_sklib.py, you'll need to change pin functions from things like Pin.PWROUT to Pin.types.PWROUT. (I'll need to fix SKiDL to allow the shorter version of pin functions.)
4. On line 125 of gamete.py, prepend gen. to Diode_SMD to access the part inside the generic_parts file.

After making these changes, I was able to get your code to compile. There were a lot of unconnected pin warnings and such, but you probably expected those.

Thank you very much.

I figured there was a naming convention I wasn't aware of.

About the Pin.types.PWROUT, are these files just bit-rotted?
