Hello All
Good Day to you!

In my application I have saved received data from UART to "Rx_reg" array. Now i want to check whether the received data is "DISC" or not. How to do this? Appreciate if you share some sample code for the same. Thank you!

You can use string compare or you can write program like this
Code C - [expand]
1
2
3

char function(void)
{
char string[];
char number[]= "xxxxxxxxxx";
 
for(i = 0; string[i] != 0; i++)
 {
   if(string[i] == num[0])
   {
     for(j = 0; num[j]!= 0; j++)
     if(string[i + j] != num[j])
     break;
   
     if(num[j] == 0)
     return TRUE
   }
}
return FALSE
}
 

The code provided by Venkadesh_M can be used as string compare function and if it returns true. U can switch a LED ON for visual confirmation. Or else u can use same UART and send the same string on UART starting from first character, u will see the string on ur hyper terminal or teraterm. Or u can use alphanumeric LCD to display the strings.

Hope that helps.
 

I presume the above variable number[] should be renamed to num[], otherwise would be nerver used on code.
