I try receive byte over interrupt when port get it (without infinite loop for get bytes). My code is below. May be it is wrong, but if not made two my corrections bytes not be received.
I tested my code at 9600 and 115200 baud.
By the way. What is LL-driver? Could I get it ? Could I get example for used it ?
Becourse I see possible mistakes at UART HAL-driver. It work for transfer some bytes only. If need bulk transfer (about hundred thousand) both HAL_UART_Transmit_DMA as HAL_UART_Transmit_IT make bugs... I don't khow why. Only HAL_UART_Transmit work correct.
May be I don't understand work with UART HAL-driver.
======== my code start ========================
// after init UART -------------------------start
#define iBufRecSize 2
char rx_buffer[iBufRecSize];
// Define buffer for receive 2 bytes only
huart1.RxXferSize = iBufRecSize;
huart1.pRxBuffPtr = (uint8_t *) & rx_buffer;
// But CallBack must be call after 1 byte
huart1.RxXferCount = 1;
// Enable Interrupt for receive byte
__HAL_UART_ENABLE_IT(& huart1,UART_IT_RXNE);
// after init UART ---------------------------------------end
// CallBack Function -------------------------start
void HAL_UART_RxCpltCallback(UART_HandleTypeDef *UartHandle)
{
// Get One byte
char * point;
point = (char *) UartHandle->pRxBuffPtr;
point --; // After Received Symbol Pointer Move To Next
<Place Where Save Received Byte> = * point;
// Repeat Initialize For Receive One Byte
UartHandle->pRxBuffPtr = (uint8_t *) & rx_buffer;
UartHandle->RxXferCount = 1;
UartHandle->RxXferSize = iBufRecSize;
__HAL_UART_ENABLE_IT(UartHandle,UART_IT_RXNE);
