OverflowError: Python int too large to convert to C long about pifacecommon HOT 5 CLOSED

Could you run with that fix for a while and see if it errors again? I'll try and get to the bottom of this! Thanks.

Ok, I've merged a fix into the testing branch. It's not a direct fix but I've implemented the SPI transfer more closely to how you're supposed to do it in C. Hopefully, by letting the the include file do the heavy lifting the bug should disappear! Let me know how you get on. I'll merge it into master later today, if there aren't any issues.

You have a typo in linux_spi_spidev.py.
line 3
from asm_generic_ioctl import _IOR, _IOW, _IOC_SIZEBITS
is missing a dot before "asm_generic_ioctl", like:
from .asm_generic_ioctl import _IOR, _IOW, _IOC_SIZEBITS

The problem was detected at the install of pifacedigitalio (see bellow). But because pifacedigitalio downloaded locally the master branch of pifacecommon, the install finished, but without the fix...
I fixed the typo and going to test the fix.

cd pifacedigitalio
sudo ./install.sh

Ah, I fixed that on my local copy but I haven't updated it. Everything seems to work for me but since I don't really know how to replicate the error your in a better position to test it. I'll upload my changes to the testing branch in merge it into master by the end of the week if all goes well.

I do not have error with the last fix.
Thanks
