LED_Output right
by 1 bit position
END
Similar to the previous lab, Decide() checks the LED_Output variable value before
executing the shift to ensure that the variable is not all 0 ’s or that the Most Significant
bit, for a left shift, or Least Significant bit, for a right shift, are not ‘ 1 ’, indicating that the
shift that follows will fill the LED_Output variable with 0 ’s.
The Do_Outputs() simply assigns the contents of the LED_Output variable to the
PORTC register lighting the connected LEDs accordingly.

PROCEDURE
Using the firmware developed in the previous lab, make the following changes:
Copy/paste the code in Example 3-16 into the top of the firmware source template under the
section marked:
//--------------------DATA MEMORY----------------------
EXAMPLE 3-16:
VARIABLE DECLARATIONS FOR LAB 5
unsigned char LED_Output;//Variable used to set/clear PORTC bits
bit direction;//Variable to select direction of shifting LEDs
