SERIAL_bRxQueueEmpty()

Explanation

The SERIAL library checks whether the reception from the UART is stored in the FIFO buffer.

To retrieve data from the FIFO buffer, use SERIAL_i16RxChar().

Argument

Type	Name	Remark
uint8	u8SerialPort	Serial port (E_AHI_UART_0 or E_AHI_UART_1 should be specified)

Returns

Type	Remark
bool_t	If `TRUE`, there is received data in the FIFO queue managed by the SERIAL library. If `FALSE`, there is still data in the queue.

Sample code

void cbToCoNet_vMain(void) {
    while (!SERIAL_bRxQueueEmpty(sSerPort.u8SerialPort)) {
        int16 i16Char;
        i16Char = SERIAL_i16RxChar(sSerPort.u8SerialPort);
        vfPrintf(&sSerStream, "\n\r# [%c] --> ", i16Char);
        SERIAL_vFlush(sSerStream.u8Device);
        ...
    }
}
