Thanks for your answer!
My configure about lpuart1 as follows:
/*! lpuart1 configuration structure */
const lpuart_user_config_t lpuart1_InitConfig0 = {
.transferType = LPUART_USING_INTERRUPTS,
.baudRate = 115200U,
.parityMode = LPUART_PARITY_DISABLED,
.stopBitCount = LPUART_ONE_STOP_BIT,
.bitCountPerChar = LPUART_8_BITS_PER_CHAR,
.rxDMAChannel = 0U,
.txDMAChannel = 0U,
};
In loop function,rest on the receive circulation:
while (1)
{
/* Get the received data */
while(strReceived == false)
{
/* Because the terminal appends new line to user data,
* receive and store data into a buffer until it is received
*/
LPUART_DRV_ReceiveData(INST_LPUART1, &buffer[i], 1UL);
/* Wait for transfer to be completed */
while(LPUART_DRV_GetReceiveStatus(INST_LPUART1, &bytesRemaining) != STATUS_SUCCESS);
/* Check if current byte is new line */
if(buffer[i++] == '\n')
strReceived = true;
}
/* Append null termination to the received string */
buffer[i] = 0;
Before the loop function,send some data to remote is ok, so the communication is should be no problem, I just test the lpuart1,didn't use another function or gpio.
Best regards
