String tokenizing

Paul Marley

I need to extract eight values from a string I'm receiving from my serial port. I have the following code:

unsigned char xdata *p_ch;
unsigned int  xdata ch = 0;

// Get command
   p_ch = strtok( com_buffer, "," );

// Get status
   while ( p_ch != NULL )
   {

//    Get string
      p_ch = strtok( NULL, "," );

//    Convert to float
      ad_value[ch] = atof( p_ch );
      ch++;

      if ( ch > 8 )
        break;

    } //__while ( p_ch != NULL )__

It works very intermittently. Can anyone suggest a better way to decode my serial string?

Thanks.
