Working with Dicodes, think of their menu system as those in single button devices, where the selection is done with the use of a timeout system.
Now, the two directional buttons get rid of timeouts, but the system, at its root, remain a single button logic. If you think of it as an evolved single button menu, it becomes much easier to learn it.
I have the English PDF on my phone, because from time to time I still need an hint.
Problem with Dicodes menu come not from it being complex, but from the fact that has a completely different structure from those used in more common devices.
Once you grasp its logic, is a dream to work with Dicodes TC. I like the heat-pump mode, works very well with overwicked RTAs.
In power mode, the only differences are the longer battery life at low power; how it keeps power-steady (to the point of grinding batteries); and the smoother vape conseguent the very high operating frequency.
The wait continues.
