Hi,

     i edited ethernet to serial project. i made it 4 client connection. so my code was listening port 23,24,25,and 26 port. so

every Client i want to make seperate UART for receive and transmit. can you guide how to make further UART port.

if you give one example code related to this one. i will make 4-uart my self.

    

     just give one example. i am using KDS 2.0 IDE and KSDK 1.0.0 mqx Ethernet to serial project. i cant use SDA serial to all Client connection.

regards,

Thiva

i am waiting for code. otherwise just guide following code... inside main task i am doing this things

   

void main_task   (      uint32_t initial_data   )

{

char buf[6]="TEST";

                 PORT_HAL_SetMuxMode(PORTC_BASE,14u,kPortMuxAlt3);    //initializing uart-4

                PORT_HAL_SetMuxMode(PORTC_BASE,15u,kPortMuxAlt3);

                CLOCK_SYS_EnableUartClock(4);

        // UART clock source is either system or bus clock depending on instance

         uartSourceClock = CLOCK_SYS_GetUartFreq(4);

          // Initialize UART baud rate, bit count, parity and stop bit.

           UART_HAL_SetBaudRate(baseAddr, uartSourceClock, BOARD_DEBUG_UART_BAUD);//115200

           UART_HAL_SetBitCountPerChar(baseAddr, kUart8BitsPerChar);

          UART_HAL_SetParityMode(baseAddr, kUartParityDisabled);

         #if FSL_FEATURE_UART_HAS_STOP_BIT_CONFIG_SUPPORT

          UART_HAL_SetStopBitCount(baseAddr, kUartOneStopBit);

          UART_HAL_EnableTransmitter(baseAddr);

          UART_HAL_EnableReceiver(baseAddr);

while(1)

{

UART_DRV_SendDataBlocking(4, buf, sizeof(buf), 0);

_time_delay(3000);

}

}

but its not transmit any data  on serial what problem here......

Please review other post for example code to do this.
