Create a program using the ARMv7 instruction set to do the following:
a. Read a single pushbutton
b. Output a 0 on a seven segment display when the button is pushed in
c. Output a 1 on a seven segment display when the button is not pushed

Answer 1

The ARMv7 instruction set is used to read a single pushbutton and output a 0 or 1 on a seven segment display based on whether the button is pushed or not pushed.

Step-by-step explanation:

ARMv7 Instruction Set

The ARMv7 instruction set is a 32-bit RISC (Reduced Instruction Set Computer) architecture used in many embedded systems and mobile devices. It offers a wide range of instructions for performing various operations.

Reading a Single Pushbutton

To read a single pushbutton using the ARMv7 instruction set, you would need to interface the pushbutton with the microcontroller's GPIO pins. Once the pushbutton is connected, you can use the appropriate GPIO pin configuration and read the input status register to determine the state of the button (pushed or not pushed).

Outputting to a Seven Segment Display

To output a 0 or 1 on a seven segment display, you would need to interface the display with the microcontroller's GPIO pins. You can configure the GPIO pins to control the segments of the display. When the pushbutton is pushed, you can set the appropriate GPIO pins to display a 0 on the seven segment display. When the button is not pushed, you can set the GPIO pins to display a 1.
