The A4 firmware contains all the sub menus populated into the main menu, better adjusting precision for the voltage and currents, updated component values for calculating the voltage feedback and the current and many more.
I also added another logo message that shows the "Hackaday Prize 2017" text when the device initializes.
Also, as promised, all the comments are in English. Check all the files for more details.
Have fun and stay tuned for more updates. I added a comment at the bottom of this page stating the things that are still to come. The video is also coming soon.
