LPUART Demos Issue

Dears,

I built a new 'lpuart_echo_s32k146' project from S32SDK RTM3.0.0 with S32K146EVB, and I can see RX data, it can not reply to PC Monitor, it stuck at

while(LPUART_DRV_GetReceiveStatus(INST_LPUART1, &bytesRemaining) == STATUS_BUSY);

Can you help to advice, attached the monitor result,

BRs,

Ray

Hi,

this demo works this way. It waits for string (either finished by new line character or until buffer is full) and then it sends the string back.

Terminal program must be configured to sent '\n' character for new line, then after ENTER is pressed whole received string is sent back.

BR, Petr

Hi Petr,

Thanks for your response,

Seems I need to chage ‘\n’ to '\r‘ in Windows system, otherwise it cannot work,

BRs,
