Project Name:$-\_.$ SW$\_$Count$\_$Up$\_$Down

Description:$-$ This program should increment a binary counter "count" if pushbutton PB$0$ is pressed and decrement the counter if pushbutton PB$1$ is pressed while SW$0$ is in the ON position. The value of the binary counter is displayed on PORTB Leds. When SW$0$ is in the "OFF" position the binary counter is reset $($i$.$e all LEDs on PORTB are turned off$)$ and pushbuttons PB$0$ and PB$1$ have no effect $($i$.$e$.$ counter does not increment or decrement$).$ Pushbutton PB$0$ should also use the debounce function $($i$.$e$.$ get$\_$PB$00)$ used in the previous exercise when reading it's state. You should create a new debounce function for PB$1$ called "get$\_$PB$10".$

Instructions:$-$

$1.$ Create a macro name for the switch SW$0$:$-$

E$.$g$.\backslash$#define SW$0$ RA$0$

$2.$ Create a macro name for ON and $\backslash (\backslash$mathrm$\{$OFF$\}$:$-\backslash )$

E$.$g$.\backslash$#define ON $1$

$\backslash$#define OFF $0$

$3.$ Use the macros listed above in your program.

$4.$ Reuse and incorporate the "get$\_$PB$0()"$ function from the previous exercise. You will also need to incorporate a debounce function for PB$1$ aswell called "get$\_$PB$1()".$

$5.$ Create a variable "count" which is incremented everytime pushbutton PB$0$ is pressed and decremented while PB$1$ is pressed while SW$0$ is $"$ON$".$ The value of count is displayed by the LEDs on PORTB and is reset when SW$0$ is off. When SW$0$ is "OFF", pushbutton PB$0$ and PB$1$ have no effect on variable "count".

$6.$ Add comments to your code $($marks lost for no comments$).$

$7.$ Ensure all code is properly indented $($i$.$e$.$ marks lost for no indentation$).$
