3.3.7.1
This lab shifts a high bit in the PORTC register from right-to-left each time through the
software loop sequentially lighting the LEDs connected to the PORTC pins in 1 second
intervals as dictated by the Timing(). This lab adds some new functional blocks to
the main() software control loop as shown in Figure 3-15.
FIGURE 3-15:
The addition of an 8-bit global variable (can be manipulated by any function) called
LED_Output is used. This variable will be acted upon by the new Decide() by shift-
ing a high bit in LED_Output from right-to-left each time this function is called. The
flowchart for the Decide() is shown in Figure 3-16.
