Posted on May 17, 2011 at 09:52Dear Michael & JakBird Thanks for replying,
I am using Library given by ST. If I print string through before while it gets on PC properly therefore I think that baud rate setting is not problem. My code is as follows after configuring PLL for 96MHz.
/* Enable the UART0 Clock */
SCU_APBPeriphClockConfig(__UART0, ENABLE);
/* UART Initialization */
UART_InitStructure.UART_WordLength = UART_WordLength_8D;
UART_InitStructure.UART_StopBits = UART_StopBits_1;
UART_InitStructure.UART_Parity = UART_Parity_No ;
UART_InitStructure.UART_BaudRate = 9600;
UART_InitStructure.UART_HardwareFlowControl = UART_HardwareFlowControl_None;
UART_InitStructure.UART_Mode = UART_Mode_Tx_Rx;
UART_InitStructure.UART_FIFO = UART_FIFO_Enable;
UART_InitStructure.UART_TxFIFOLevel = UART_FIFOLevel_1_2; /* FIFO size 16 bytes, FIFO level 8 bytes */
UART_InitStructure.UART_RxFIFOLevel = UART_FIFOLevel_1_2; /* FIFO size 16 bytes, FIFO level 8 bytes */
UART_DeInit(UART0);
UART_Init(UART0, &UART_InitStructure);
/* Enable the UART0 */
UART_Cmd(UART0, ENABLE);
/* Following is the code in main */
sprintf( acString,''Any String'');
Uart0printf( acString );
<----This line works properlywhile ( 1 )
{
Uart0printf( acString );
<----This line doesn't work properly }
Following is the function which I am using for printing a stringvoid Uart0printf( char *pcString )
{
while( *pcString != '\n' )
{
UART_SendData( UART0, *pcString);
while(UART_GetFlagStatus(UART0, UART_FLAG_TxFIFOFull) != RESET);
At above position I have also tried some other flags & there SET, RESET values, even UART_Clear function also used pcString++;
}//while
}//Uart0printf
Please tell me if any mistake in above code.
