Problem $1[10$ points$]-$ABET Outcome $\text{'}$c$\text{'}$ Question $($Ability to Design a system,

component, or process to meet desired needs$)$

Design a $16$F$877$A MCU$-$Based system that would read a keypad and display the number

of the pushed key on a seven segment display.

Your design shall meet the following design requirements:

i$.$ Use the keypad shown in Figure $1\mathrm{.}1$

ii$.$ Use a common cathode seven segment display

iii. Lines $1-3$ of the keypad shown if Figure $1\mathrm{.}1$ shall be connected to PORTB pins

RB$0-$RB$2$ respectively, and Lines $4-7$ shall be connected to PORTC pins RC$0-$

RC$3.$

iv$.$ The Seven segment display data lines shall be connected to PORTD

$v.$ If the pushed button is $\text{'}\text{'}$ or $\text{'}$#$\text{'}$ display a $\text{'}0\text{'}$ on the seven segment display.

a$.[5$ points$]$ Show the electric circuit design $($label everything in your circuit

drawing$).$

b$.[5$ points$]$ Design$/$Develop the embedded software program. $($C

code$)$

please solve part a and b and please draw part a on paper
