@stiebrs Before use this dln_srv should be run and adapter is plug-in. I don't test in Windows.

Hi @stiebrs If you find solution can u share with me plss

eldarkg commented 2 years ago

@sunnybabu10 The message say that range of input parameter is incorrect (more than ushort). You can try to check this undocumented code https://github.com/eldarkg/dln-python/blob/c2f0abc5f230f6aeb5ff313c19567b8375433109/dln/client.py#L114 . Check range of 'handle' parameter.

Hi, @sunnybabu10 No, I didn't manage to get it running. I replaced it with FT232H that has SPI support and is more generic
