This might at some point become a complete oop library for STM32F4 blackpill

For a STM32CubeIDE project see develop branch

GPIO

Added GPIO class that allows to start and stop port's clock, to access it's pins using array subsckript operator, and to lock current pin setting

PIN

Added PIN class that allows to set it's mode, alternate function, speed, output type, pull-up/pull-down

helper enums

Try to eliminate unnecessary asserts and make code more readable

Usage

#include "stm32f4xx_hal.h"
#include "GPIO.hpp"

int main() {
  SystemClock_Config();
  HAL_Init();

  Speed s{};
  OType o{};
  Mode m{};
  PUPD p{};
  Alt al{};
  State val{};
  
  GPIO<C> c;
  c.Init();
  c[13].Set(Speed::High).Set(OType::OpenDrain).Set(Mode::Output).Set(PUPD::NoPUPD);
  c[13].Get(s).Get(o).Get(m).Get(p).Get(al);
  c[13].Write(Hi).Read(val);
  
  GPIO<A> a;
  a.Init();
  a[0].Set(Mode::Input).Set(OType::OpenDrain).Set(Speed::High).Set(PUPD::PullUp);
  
  while (1) { c[13].Write(a[0].Read()); } // blink on button press

  return 0;
