STM32F103C6 system consists of four common cathode LEDs, four active low Switches and a common cathode 7-segment display as shown in Figure 4. Write a metal embedded C program that performs the following task: (a) Switch ON the LEDs based on the switch number pressed on PORTA. For example, if switch PA2 is pressed, then LED2 is switched ON. (b) Display the corresponding switch number being pressed on 7-segment. For example, if switch PA2 is pressed, 7-segment will display "2". (c) If no switch is being pressed, all LEDs and 7-segment display are switched off. 100 PBO O PB1 PB2 PB3 VDD VDD R7 10k R8 10k O Led4 HI.
