Pin Function Grouping


Done — I simplified the functional groups to general names like PA, PB, VDD, VSS, VCAP, Reset, Boot, etc., and set every pin’s Section to exactly match its Pin Group.
Open items:
  • None.
Suggested next steps:
  1. Review the symbol grouping visually.
  2. Add pin descriptions or alternate-function metadata if needed.
Make the functional group and section more general.
I’ll generalize the pin metadata further: GPIO ports will become GPIO, supplies/grounds will become broad Power/Ground/Analog, and each pin’s Section will match its Pin Group.
Done — I generalized the groups further: all port pins are now GPIO, supplies/regulator pins are Power, grounds are Ground, VREF+ is Analog, and reset/boot are Control. Each pin’s Section matches its Pin Group.
Open items:
  • None.
Suggested next steps:
  1. Visually review the symbol grouping.
  2. Add detailed pin descriptions separately if you still want per-pin specificity without granular groups.
