Hello all,
I have two schematics I'm working on for a school project. We're designing a sun-tracking solar panel array, and I'm working on the (very preliminary) schematics. I really don't know much about best practices for schematic design, especially for hierarchical sheets as this is my first time using them, and so I was hoping someone could take a look and give me some advice on how to neaten them up.
I'm not looking for circuitry related stuff, I wouldn't ask someone to go through all the datasheets and find all the connection and/or value errors I've made, just advice to make the schematics neater and easier to understand. (I mean, I'm not going to stop you if you want to
)
Especially my main question, when should I use hierarchical pins vs global labels? It seems like global labels make the thing neater, especially on things like voltage sources, but they don't really show the connections on the main sheet at all.
there are two schematics, one for the panel movement controller, and one for the MPPT controller (basically a slightly different buck converter). I have them separate currently because I don't know how much processing power the MPPT needs (seems heavy, since it needs to output a frequently changing ~100Khz pwm.)
It may be possible to control both functions with a single MCU, if anyone has any thoughts/advice on that, I would also very much appreciate it.
Thank you very much!
Adding Pictures here. Sorry, should have thought of that sooner!
