uratprintf() not functioning at all in tiva ware seriers

Hi,

     Provide more relevant details. What Tiva Microcontroller, Tiva Kit, IDE are you using?

     See, my signature below link "Information to provide when asking for help".

     Did you add uartsdio at your libraries?  See, below.

I'm using TM4 C232H5QC  n keil ide..no ididn't add uartstdio.c files to library files..

Hi Rashimi,

     Right click your project at project view and then go to "Manage Components". Add uartstdio.c under libraries.

Hi,

UARTprint function is configured to work only with UART 0,1,2, corresponding to stdin, stdout and stderr in Unix/Linux environment.

Last week was a disscution on this forum and Amit suggested a workaround. Search that thread.

K Thank you for your information..Is their any function to   print the string using uart 7????

Yes, use the system sprint() function to print to a buffer then use the UARTSend routine to send the buffer to UART7.

Hi...now i have modified my program like this..

char ab[12] = "rashmi";
long val;

void
UARTSend(const unsigned char *pucBuffer, unsigned long ulCount)
{
//
// Loop while there are more characters to send.
//
while(ulCount--)
{
//
// Write the next character to the UART.
//
UARTCharPutNonBlocking(UART7_BASE, *pucBuffer++);
}
}

int main(void)
{

volatile char ulTempValueC;
SysCtlClockSet(SYSCTL_SYSDIV_1 | SYSCTL_USE_OSC| SYSCTL_OSC_MAIN | SYSCTL_XTAL_8MHZ);

SysCtlPeripheralEnable(SYSCTL_PERIPH_UART7);
SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOE);
GPIOPinConfigure(GPIO_PE0_U7RX);
GPIOPinConfigure(GPIO_PE1_U7TX);
GPIOPinTypeUART(GPIO_PORTE_BASE, GPIO_PIN_0 | GPIO_PIN_1);



UARTConfigSetExpClk(UART7_BASE, SysCtlClockGet(),9600,(UART_CONFIG_WLEN_8 | UART_CONFIG_STOP_ONE | UART_CONFIG_PAR_NONE));


UARTEnable(UART7_BASE);


sprintf( ab, "%c", ulTempValueC );

UARTSend((unsigned char *)ab,12);
while(1);

}

in teraterm ,it is not displaying properly..why so??

Hi, 

At least you should explain what you mean by " not displaying properly" - well, your format parameter in sprintf is %c which is dedicated for printing chars, while you want to display an integer -change it to %d and check again. 

Also it would be wise to read some info about formatting, Google search...

i'm going to display character..If i use only UARTSend((unsigned char *)ab,12); function then i can display properly in teraterm ..

here ab means

char ab[12] = "rashmi"

"%d" transform a binary number into characters in ab array/string, to be human readable.

As I said in previous post, check/search documentation about formatting for printf/sprintf/snprintf.

K Thank  you....
