Please write using ARM Assembly for STM$32$F$411$VETx and an STM$32$Microcontroller$.$ The modes interact with the LEDs on the board, and should be subroutines. It should all be one block of code.

$******$Please note the attached screenshot is an example of what our code has looked like in the past!

While the function of the attached code will not help while answering this question, im hoping it should help you understand the snytax and formatting for this code.$******$

The final project will entail writing a program with three modes:

Mode $A-$ The lights will start all off, then turn on $($and stay on$)$ one at a time: orange, then

red, then blue, and lastly green. They will then turn off $($and stay off$)$ one at a time in that

same order. Once all are off, the cycle will repeat. Put a $0\mathrm{.}25$ second pause between each

change. $($For example, if all lights are off, the orange LED will come on and stay on$,$ then

$0\mathrm{.}25$ seconds later the red LED will also come on$.0\mathrm{.}25$ seconds after that, the blue LED will

come on$,$ etc.$)$

Mode B $-$ The blue light will toggle$/$blink once per second, the red light will toggle every $0\mathrm{.}75$

seconds, the orange light will toggle every half second, and the green light will toggle every

$0\mathrm{.}25$ seconds.

Mode $C-$ The program will read in byte values from a null$-$terminated, read$-$only array called

ModeCVals and display them on the lights. If the value is between $1$ and $15,$ the bits will

correspond such that PD $15$ represents bit $3,$ PD$14$ for bit $2,$ PD$13$ for bit $1,$ and PD$12$ for

bit $0.$ For example, if the value to be displayed is $6,$ that's $2\_00000110$ so PD$15$ would be

off, PD$14$ and PD$13$ would be on$,$ and PD$12$ would be off. If the value in the array is larger

than decimal fifteen $(OOF),$ do not turn on any of the lights for its representation. Each

value's LED representation should display for one second before changing directly to the

next value. The null$-$termination character counts as a value $($it$\text{'}$s zero$).$ After displaying

the final $(000)$ value, loop around to the beginning of the ModCVals array and start

displaying the values from the beginning again.

The user will switch between these modes by pressing the PAO input button. The change in

mode can occur at any point during the mode $($as opposed to finishing the cycle of blinks

before starting the next. When the button is pressed while the program is on Mode $C,$ it

should "loop around" and begin Mode A again.

Hints: Use an interrupt for the input. Debounce your input. If a timer triggers every $0\mathrm{.}25$

seconds, then something that occurs every third timer trigger will occur once every $0\mathrm{.}75$

seconds. Moving bits $3$ through $0$ to bits $15$ through $12$ is a matter of shifting. Make DATA

area values to be used as counters or to track what mode you're in$.$The final project will entail writing a program with three modes:
