how to convert uint8 to string for printf out？

The Seven

Hi all

i have got the LQI and Rssi data ， and i want to using HalUARTWrite（） for printf out those data.

      char szLine[50];
      uint8 OutputCnt=0;
      osal_memcpy(szLine, "Rssi=0x",7);  //7
      zclHA_uint8toa( Rssi_temp, &szLine[7] );//3 
      osal_memcpy(&szLine[10], ",LQI=0x", 7); //7 
      zclHA_uint8toa( Rssi_temp, &szLine[17] );//3
      OutputCnt = 20;
      HalUARTWrite(0,szLine,OutputCnt);

there is always messy code when uart printf out ~~~~

does anybody knows why ？

BR!

You can use sprint to format string into szLine.

Hi yikai

there is always messy code while i using sprint function like below：

    char str1[20];   
    sprintf(str1,"Rssi=%x,LQI=%x",Rssi_temp,LQI_temp);
    HalUARTWrite(0,str1,sizeof str1);

If you set a breakpoint on "HalUARTWrite(0,str1,sizeof str1);" and stop there, what do you see in str1 from IAR IDE?

those code is put into the zclEmerButton_ProcessInDefaultRspCmd( zclIncomingMsg_t *pInMsg ) function

I Don‘t know why does i could not set a break point in it

Try to set optimization level to low in your IAR IDE.

yes i have set optimization level as none ， then i could set breakpoint ，

but i could not always get the str1 value ， anyway ， as we could see there is a value of Rssi_temp ，but IAR IDE could not show in the debug window

Declare str1 as global variable instead of local variable.

Hi Yikai

it is OK when i running a debug mode ，stop in the breakpoint and then run again， and uart printf out is right。

but when it does not running the debug mode ， it could not print out the right code for uart

Try to remove MT_TASK define from your compile options.

it does not work when i remove MT_TASK

Try to also disable ZTOOL_P1 in your compile options.

disabled ZTOOL_P1 ，there is not out put to the uart

Disable ZTOOL_P1 and follow steps in sunmaysky.blogspot.tw/.../how-to-use-two-uart-ports-in-cc2530-z.html to init UART.

thanks yikai ， it works ！

but do you know why cause the messy code ？？？

is that the problem of MT_UartProcessZToolData（）

#if defined (ZTOOL_P1) || defined (ZTOOL_P2)
uartConfig.callBackFunc = MT_UartProcessZToolData;
#elif defined (ZAPP_P1) || defined (ZAPP_P2)
uartConfig.callBackFunc = MT_UartProcessZAppData;
#else uartConfig.callBackFunc = NULL;
#endif

I believe it's caused by MT related code somewhere. It's good to know it works now.
