Sending value through UART7

Hi,

I am using TM4C123GH6PM evaluation kit and CCS. I need to develop a code, to transmit a value and receive another value through UART7 continuously and the received value need to be displayed in the windows terminal through UART0. I developed the following code from uart_echo example.

void
UARTIntHandler(void)
{

	uint32_t ui32Status;
    ui32Status = ROM_UARTIntStatus(UART0_BASE, true);

    ROM_UARTIntClear(UART0_BASE, ui32Status);

    while(ROM_UARTCharsAvail(UART0_BASE))
    {

        ROM_UARTCharPutNonBlocking(UART7_BASE,
                                   ROM_UARTCharGetNonBlocking(UART0_BASE));

        GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_2, GPIO_PIN_2);

        SysCtlDelay(SysCtlClockGet() / (1000 * 3));

        GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_2, 0);

    }
}

void
UART7IntHandler(void)
{

	uint32_t ui32Status;
    ui32Status = ROM_UARTIntStatus(UART7_BASE, true);

    ROM_UARTIntClear(UART7_BASE, ui32Status);

    while(ROM_UARTCharsAvail(UART7_BASE))
    {

        ROM_UARTCharPutNonBlocking(UART0_BASE,
                                   ROM_UARTCharGetNonBlocking(UART7_BASE));

        GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_2, GPIO_PIN_2);

        SysCtlDelay(SysCtlClockGet() / (1000 * 3));

        GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_2, 0);

    }
}

void
UARTSend(const uint8_t *pui8Buffer, uint32_t ui32Count)
{

    while(ui32Count--)
    {
        ROM_UARTCharPutNonBlocking(UART7_BASE, *pui8Buffer++);
    }
}

int
main(void)
{

    ROM_FPUEnable();
    ROM_FPULazyStackingEnable();

    ROM_SysCtlClockSet(SYSCTL_SYSDIV_1 | SYSCTL_USE_OSC | SYSCTL_OSC_MAIN |
                       SYSCTL_XTAL_16MHZ);

    ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF);

    ROM_GPIOPinTypeGPIOOutput(GPIO_PORTF_BASE, GPIO_PIN_2);

    ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_UART0);
    ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOA);
    ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_UART7);
    ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOE);

    ROM_IntMasterEnable();

    GPIOPinConfigure(GPIO_PA0_U0RX);
    GPIOPinConfigure(GPIO_PA1_U0TX);
    GPIOPinConfigure(GPIO_PE0_U7RX);
    GPIOPinConfigure(GPIO_PE1_U7TX);

    ROM_GPIOPinTypeUART(GPIO_PORTA_BASE, GPIO_PIN_0 | GPIO_PIN_1);
    ROM_GPIOPinTypeUART(GPIO_PORTE_BASE, GPIO_PIN_0 | GPIO_PIN_1);

    ROM_UARTConfigSetExpClk(UART0_BASE, ROM_SysCtlClockGet(), 115200,
                            (UART_CONFIG_WLEN_8 | UART_CONFIG_STOP_ONE |
                             UART_CONFIG_PAR_NONE));
    ROM_UARTConfigSetExpClk(UART7_BASE, ROM_SysCtlClockGet(), 115200,
                            (UART_CONFIG_WLEN_8 | UART_CONFIG_STOP_ONE |
                             UART_CONFIG_PAR_NONE));

    ROM_IntEnable(INT_UART0);
    ROM_IntEnable(INT_UART7);

    ROM_UARTIntEnable(UART0_BASE, UART_INT_RX | UART_INT_RT);
    ROM_UARTIntEnable(UART7_BASE, UART_INT_RX | UART_INT_RT);
    while(1)
    {
        UARTSend((uint8_t *)"\n 1 \n ", 3);
    }
}

This code works with transmitting '1'. But I need to send a value which is changing over time. like "TempValueC". For that how can I modify the code?
