Printing data from UART

Hi,

I am using Smartrf 05 Evaluation Board Rev 1.8.1 with cc2530 chip attached.

I want to modify SampleHeatingCoolingUnit code to display data from Uart. So when i send something from Uart (RealTerm program) i want to display that on LCD display.

static uint16 HalUARTReadDMA(uint8 *buf, uint16 len)
{
uint16 cnt;
for (cnt = 0; cnt < len; cnt++)
{
    if (!HAL_UART_DMA_NEW_RX_BYTE(dmaCfg.rxHead))
    {
      break;
    }
    *buf++ = HAL_UART_DMA_GET_RX_BYTE(dmaCfg.rxHead);
    HAL_UART_DMA_CLR_RX_BYTE(dmaCfg.rxHead);
#if HAL_UART_DMA_RX_MAX == 256
    (dmaCfg.rxHead)++;
#else
    if (++(dmaCfg.rxHead) >= HAL_UART_DMA_RX_MAX)
    {
      dmaCfg.rxHead = 0;
    }
#endif
    char str[10];
    sprintf(str,"UART: %d",(uint32)dmaCfg.rxBuf[0]);
    HalLcdWriteString(str,HAL_LCD_LINE_1);
    HalLcdWriteValue( (uint32)dmaCfg.rxHead, 10, HAL_LCD_LINE_2);
    HalLcdWriteValue( (uint32)buf, 10, HAL_LCD_LINE_3 );
}
PxOUT &= ~HAL_UART_Px_RTS; // Re-enable the flow on any read.

return cnt;
}
