Hi @Community member ,
Are you create your project with STM32CubeMX? I highly recommend, it's a piece of cake to configure and generate all peripherals code!
You can use advanced macros to swap arduino standard routines with STM32CubeMX, like this:
// Define the GPIO pin and port, that was originally connected arduino Digital 10 and 11, in the STM32.
#define D10_Pin GPIO_PIN_4
#define D10_GPIO_Port GPIOC
#define D11_Pin GPIO_PIN_5
#define D11_GPIO_Port GPIOC
// Advanced macro to swap routine names and parameters.
#define digitalWrite(PIN_NAME,PIN_STATE) HAL_GPIO_WritePin(D##PIN_NAME##_GPIO_Port,D##PIN_NAME##_Pin,GPIO_PIN_##PIN_STATE)
#define digitalRead(PIN_NAME) HAL_GPIO_ReadPin(D##PIN_NAME##_GPIO_Port,D##PIN_NAME##_Pin)
// Simple test of this implementation. Should work like a champ!
void test (){
if( digitalRead(11) )
digitalWrite(10,SET);
else
digitalWrite(10,RESET);
}
You can put this code in another C file, I recommend create it in the Middlewares folder, like this: "Middlewares/MyCode/source".
In the main.c file, add the prototypes:
void setup ();
void loop ();
Between USER_CODE labels.
And in the main routine, add setup and loop calls:
int main () {
[...] // STM32CumeMX code Generated.
/* Infinite loop */
/* USER CODE BEGIN WHILE */
setup();
while (1)
{
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
loop();
}
/* USER CODE END 3 */
}
Be aware of the USER CODE labels, as the STM32CubeMX will only leave user code between this labels! Otherwise It will be deleted every time you generate code!!

Or you can simply refactor code using "Refactor->Rename... Alt+Shift+R" tool in every routine and pin names.
Best regards.
