1. LED blinking

   #include "wirish.h"
    
   //Make sure, you have connected your LED in series with resistor and MCU pin.
    
   #define LED_PIN PA1 //LED is connected to pin PA1
    
   //This method have to be called in main function in main.c file
   void app(void)
   {
      //Setting pin mode of LED_PIN to OUTPUT
      pinMode(LED_PIN,OUTPUT);
    
      //Infinite loop
      while (1)
      {
          //Toggling pin status (where LED is connected) every 500ms.
          digitalToggle(LED_PIN);
    
          //Blocking processor for 500ms
          delay(500);
      }
   }

2. NonBlocking LED blinking

   #include "wirish.h"
    
   //Make sure, you have connected your LED in series with resistor and MCU pin.
    
   #define LED_PIN PA1 //LED is connected to pin PA1
    
   unsigned long next_toggle_millis = 0;
    
   //This method have to be called in main function in main.c file
   void app(void)
   {
      //Setting pin mode of LED_PIN to OUTPUT
      pinMode(LED_PIN,OUTPUT);
    
      //Infinite loop
      while (1)
      {
          //Checking if milliseconds from program start exceeded next_toggle_millis value
          if(next_toggle_millis <= millis()){
              //Toggling pin status (where LED is connected) every 500ms.
              digitalToggle(LED_PIN);
    
              //Assigning new value to next_toggle_millis. The value is time in ms, when pin status will be toggled again.
              next_toggle_millis = millis() + 500; //milliseconds from program start + 500ms
          }
    
          //There you can call your function, while led is blinking.
      }
   }

3. LED blinking with button

   #include "wirish.h"
    
   //Make sure, you have connected your LED in series with resistor and MCU pin.
    
   #define LED_PIN PA1 //LED is connected to pin PA1
   //Connection:   PA1------LED-----100Ohm_RESISTOR------GND
   #define BUTTON_PIN PA2 //button is connected to pin PA2
   //Connection:   PA2------BUTTON------3V3
    
   //This method have to be called in main function in main.c file
   void app(void)
   {
      //Setting pin mode of LED_PIN to OUTPUT
      pinMode(LED_PIN,OUTPUT);
    
      //Setting pin mode of BUTTON_PIN to INPUT_PULLDOWN
      //It will connects PULLDOWN resistor between BUTTON_PIN and GND
      pinMode(BUTTON_PIN,INPUT_PULLDOWN);
    
      //Infinite loop
      while (1)
      {
          //Reading button pin state
          bool buttonState = digitalRead(BUTTON_PIN);
    
          //Writing LED pin state
          digitalWrite(LED_PIN, buttonState);
      }
   }

4. LED blinking with button using interrupts

   #include "wirish.h"
    
   //Make sure, you have connected your LED in series with resistor and MCU pin.
    
   #define LED_PIN PA1 //LED is connected to pin PA1
   //Connection:   PA1------LED-----100Ohm_RESISTOR------GND
   #define BUTTON_PIN PA2 //button is connected to pin PA2
   //Connection:   PA2------BUTTON------3V3
    
   //This function will be called when BUTTON_PIN state will change
   void buttonTouchedHandler(){
      //Reading button pin state
      bool buttonState = digitalRead(BUTTON_PIN);
    
      //Writing LED pin state
      digitalWrite(LED_PIN, buttonState);
   }
    
   //This method have to be called in main function in main.c file
   void app(void)
   {
      //Setting pin mode of LED_PIN to OUTPUT
      pinMode(LED_PIN,OUTPUT);
    
      //Setting pin mode of BUTTON_PIN to INPUT_PULLDOWN
      //It will connects PULLDOWN resistor between BUTTON_PIN and GND
      pinMode(BUTTON_PIN,INPUT_PULLDOWN);
    
      //Attaching interrupt to BUTTON_PIN, setting callback function and setting interrupt mode to CHANGE
      attachInterrupt(BUTTON_PIN, buttonTouchedHandler, CHANGE);
    
      //Infinite loop
      while (1)
      {
          //Nothing to do here
      }
   }

Note

Those examples works only with c++, but STM32CubeIDE does not allow you to change main.c to main.cpp, so you have to create own c++ file, and include it in main.h. In your cpp file create function, that will be called in main() function. In this case, function name is app() and is called in main() function between tags USER CODE BEGIN 2 and USER CODE END 2.
