Hello,

I am using two UARTs in my system.One UART is for transmission and one UART is reception in duplex mode.

Here is a part of my Program

for(;;)

    {

        /* Place your application code here. */

//Wait for command

recv_byte=0;

UART_1_WriteTxData(0x0d);UART_1_WriteTxData(0x0a);

UART_1_PutString("Company Name.......");

         CyDelay(20);UART_1_WriteTxData(0x0d);CyDelay(20);UART_1_WriteTxData(0x0a);

CyDelay(20);UART_1_WriteTxData(0x0d);CyDelay(20);UART_1_WriteTxData(0x0a);

UART_1_PutString("auoto Zero  => Z");

          CyDelay(20);UART_1_WriteTxData(0x0d);CyDelay(20);UART_1_WriteTxData(0x0a);

UART_1_PutString("Measure     => M");

       CyDelay(20);UART_1_WriteTxData(0x0d);CyDelay(20);UART_1_WriteTxData(0x0a);

UART_1_PutString("Setup       => S");

        CyDelay(20);UART_1_WriteTxData(0x0d);CyDelay(20);UART_1_WriteTxData(0x0a);CyDelay(20);

UART_1_PutString("display oN  => N");

         CyDelay(20);UART_1_WriteTxData(0x0d);CyDelay(20);UART_1_WriteTxData(0x0a);CyDelay(20);

UART_1_PutString("display oFf => F");

         CyDelay(20);UART_1_WriteTxData(0x0d);CyDelay(20);UART_1_WriteTxData(0x0a);CyDelay(20);

UART_1_PutString("display Test=> T");

         CyDelay(20);UART_1_WriteTxData(0x0d);CyDelay(20);UART_1_WriteTxData(0x0a);CyDelay(20);

CyDelay(20);

.

.

so on.............and I am displaying all these datas through serial port in Hyperterminal in a PC

the problem that now I am facing is,there is only one or two lines is displaying or transmitting.After that the execution of the program is in a Pause state.

Can anyone please tell what is the reason for this problem ?

Would you mind to zip and post your complete project here, so we can have a look at all possibilities that cause your problem?

If you "Clean" your project before zipping it becomes smaller, there is a 2MB limit for uploads afaik.

At (very) first sight I can see, that you use the WriteTxData() API without checking the transmitter status. This will resullt in errorneous transmission of data..

What are your Delays for? Waiting until the data is transmitted? It will go better checking the status.

Use the PutChar() API instead, which will block, if the UART is busy or the transmit-buffer / FiFo is full.

The PutString() API already blocks, so there's no need to wait for it.
