Using the PIC micro and$/$or ESP$32$ development kit and Flowcode software platform by Matrix

Solutions Ltd$,$ configure PORT A as input and ensure the push button switches are connected to

this port. Configure PORT B as output and ensure the LEDs are connected to this port. When

downloaded to the PIC, the program needs to control the LEDs based on the status of PORT A$,$

as required by the exercise below.

$1.$ When the switch S$1$ is ON $($PORT A$0$ is $1),$ the LEDs will light up as a $3-$bit binary up$-$counter

$($counting up$).$

$2.$ When S$1$ is OFF $($PORT A$0$ is $0),$ the LEDs will light up as a $3-$bit binary down$-$counter

$($counting down$).$

$3.$ Repeat the above steps with LEDs for a $4-$bit up and down counter, when switch S$2$ is

ON$/$OFF $($PORT A$1$ is $1$ or $0).$ What are the conditions assumed for a valid operation?

$4.$ Implement and demonstrate both via simulation and using the development board hardware.

Note: Check how the switches are configured. You would want the switches to be in the right position

when the program checks for their status!

Portfolio submission:

In addition to providing evidence of the correct operation of your circuits, you should also explain

the method of implementation for the count$-$up and count$-$down operations, and the different code

sequences that could be used to light up the LEDs in the required sequence
