We will create an application code and then we will move part of the code to RAM.

Code to be added:

in main.c:

/* USER CODE BEGIN 2 */  

   LL_USART_EnableIT_RXNE(USART2);

   LL_USART_EnableIT_ERROR(USART2);

...

/* USER CODE BEGIN 4 */

void USART_CharReception_Callback(void)

{

   uint8_t received_char;

   received_char = LL_USART_ReceiveData8(USART2);

   if ((received_char == 'E') || (received_char == 'e')) {

      LL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin);

   }

   LL_USART_TransmitData8(USART2, received_char);

}

in main.h:

/* USER CODE BEGIN EFP */

void USART_CharReception_Callback(void);

/* USER CODE END EFP */

in stm32c0xx_it.c:

/* USER CODE BEGIN USART2_IRQn 0 */

USART_CharReception_Callback();

/* USER CODE END USART2_IRQn 0 */

in STM32C031C6TX_FLASH.ld:

*/Drivers/*(.text*) 

*main.o(.text.MX_GPIO_Init)

*main.o(.text.MX_USART2_UART_Init)

*main.o(.text.USART_CharReception_Callback)

______
