Question

1.      Assume there are 8 LEDs on a development board and also assume that LEDs blink with step 1 and 2 pattern recursively on 8 LEDs . Also assume that the LEDs are active-high enabled on the development board.

a.       Write a C program that performs a LED blinking pattern. Grading: header/include file declaration (1 pts), I/O ports declaration (1 pts), delay function (1 pts), LED patterns




a.      Draw a LED wiring diagram that allows a LED to come on with a low signal and to come off with a high signal.

Explanation / Answer

A microcontroller (MCU) is a system-on-chip that you can find in all

kinds of embedded systems.
