I have a problem with the ADC DAC pi. When I try the example that is given on the website (demo-dacwrite.py), or when I use the command: from ABE_ADCDACPi import ADCDACPi, I have the following answer:

Traceback (most recent call last):
  File "/home/pi/ABElectronics_Python_Libraries/ADCDACPi/demo-dacwrite.py", line 3, in <module>
    from ABE_ADCDACPi import ADCDACPi
  File "/home/pi/ABElectronics_Python_Libraries/ADCDACPi/ABE_ADCDACPi.py", line 48, in <module>
    class ADCDACPi:
  File "/home/pi/ABElectronics_Python_Libraries/ADCDACPi/ABE_ADCDACPi.py", line 55, in ADCDACPi
    spiADC.open(0, 0)
FileNotFoundError: [Errno 2] No such file or directory

Someone can help me?

When you run the demo-dacwrite.py make sure the ABE_ADCDACPi.py library is in the same folder.  Another possible cause for the error could be the library is having trouble communicating with the SPI bus.  Try going through our SPI tutorial  to make sure the SPI bus is installed correctly on the Raspberry Pi.

To get rid of this error you can try using Python file exists methods to check that at least python sees the file exists or not. In other words, you can make sure that the user has indeed typed a correct path for a real existing file.  If the user does not pass the full path  to the file, the path is interpreted relatively to the current working directory. The current working directory usually is the directory in which you started the program.
