Can anyone give me a serial port interrupt receiving program for STM32F03 without HAL library?

Can anyone give me a serial port interrupt receiving program for STM32F03 without HAL library? [Copy link]

Can anyone give me a non-HAL library STM32F03 serial interrupt receiving program? Self-written or old program library is fine.

The LL library is as follows, see if you can use it.

/**
* @brief This function handles USART1 global interrupt.
*/
void USART1_IRQHandler(void)
{
/* USER CODE BEGIN USART1_IRQn 0 */
if (LL_USART_IsActiveFlag_RXNE(USART1)) {
uart[0].rdBuff[uart[0].rdPtr++] = LL_USART_ReceiveData8(USART1);
if (uart[0].rdEnabled==1) {
if (uart[0].rdPtr==1 && uart[0].rdBuff[0]!=0xBB) uart[0].rdPtr=0;
if (uart[0].rdPtr==2 && uart[0].rdBuff[1]!=0x66) uart[0].rdPtr=0;
if (uart[0].rdPtr==3 && uart[0].rdBuff[2]!=0x66) uart[0].rdPtr=0;
if (uart[0].rdPtr==4 && uart[0].rdBuff[3]!=0xBB) uart[0].rdPtr=0;
}
else uart[0].rdPtr=0;
LL_USART_ClearFlag_RXNE(USART1);
}
else if (LL_USART_IsActiveFlag_IDLE(USART1)) {
uart[0].rdEnded=1;
LL_USART_ClearFlag_IDLE(USART1);
}

/* USER CODE END USART1_IRQn 0 */

Thank you, this program cannot be used because my version does not have the routine of LL_USART_ClearFlag_RXNE library. Can you send me the source code of your LL_USART_ClearFlag_RXNE routine?

Thank you for your answers. The problem is not due to these reasons, but the problem of calling array in the main loop. It has been solved now.
