Running python3 SoC-CircuitPython.py fails

[JamesTimothyMeech]

When I run python3 SoC-CircuitPython.py I get this error:

AttributeError: module 'inspect' has no attribute 'getargspec'. Did you mean: 'getargs'?

I assume that this means I should be using an earlier version of python. Which version should I be using?

[gregdavill]

Which version of python are you using now? Ideally this should be updated, rather than you needing to downgrade.

I think I am close to get it working, but I may need some help with a last bit: https://github.com/orangecrab-fpga/orangecrab-examples/pull/36
