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;
}

Whenever i tried do display values i got buffer size and amount of data that i sent, never exact string that i send.

I am stuck now, dont know what to do, can someone pls help me?
