printf("..") to terminal using FRDM board

[allenwong]

Hello folks,

What's wrong with my code below:

for(;;) {

      y=x % 3;

      if(y==1)

      {

          LED_G_SetVal(Green_Ptr);

          LED_B_SetVal(Blue_Ptr);

          LED_R_NegVal(Red_Ptr);

      }

      printf("\r\nRed LED\r\n");     /*Red LED Output to Terminal*/

I can't see the "Red LED" in terminal output.

Do i need to include any delay?
