The main changed between this and the non-NAC3 TTL4_50Hz.
@nac3 decorator on the classes used by the artiq compiler.
delay(20 * ms) -> delay(20.0 * ms). The old version is incorrect because 20 is
int32 and ms is float. Typing is much more strict.
Type hinting changes: the old TNone and TStr has been depriciated. (print_elapsed_time)

Here's the NAC3 code, I get the following error from artiq.experiment import nac3, delay, ms, kernel, EnvExperiment
ImportError: cannot import name 'nac3' from 'artiq.experiment' (C:\Users\James\anaconda3\envs\artiq\lib\site-packages\artiq\experiment.py). It does look like nac3 was installed, but perhaps not into the conda environment Im using? Since I've been following the documentation, I installed the base artiq module into a conda environment called "artiq".
