Try to use SPI function in digital discovery in Linux. Undefined symbol

[minghan chao]

The error is the following

File "/usr/lib64/python3.7/ctypes/__init__.py", line 369, in __getattr__
    func = self.__getitem__(name)
  File "/usr/lib64/python3.7/ctypes/__init__.py", line 374, in __getitem__
    func = self._FuncPtr((name_or_ordinal, self))
AttributeError: /usr/lib/libdwf.so: undefined symbol: FDwfDigitalSpiSelectSet
pure virtual method called
terminate called without an active exception
Aborted
 

I tried to use SPI built in function for digital discovery. FDwfDigitalSpiSelectSet and other spi functions are what I try to use.

My code works in Windows environment, but in Linux system, I got this error. Actually, I have some codes running (mostly IO stuff) on Linux system, but this code involving SPI built-in function is not working. The libdwf.so may have some problems. Could you please help me to solve this problem? Thanks.

Hi @minghan chao

Probably you have a very old digilent.waveforms installed without this function. You can find the latest software at:
