 Probleml: Write a code to operates a Permanent Magnet DC Motor

Probleml: Write a code to operates a Permanent Magnet DC Motor (PMDC Motor) in four different speed using four push buttons connected on RB4 to RB7 pins. (You must use PORTB on change interrupt). *Attach .asm file do not send picture to code. Problem2: Write a code using PWM technique to get a speed profile for soft start/stop motors such as following timing-diagram. - The START push button must be pressed to generate this timing-diagram. -PWM Duty Cycle increased/decreased by 5% every 0.1 Sec. *Attach .asm file do not send picture to code. 110.00% 100.00% 90.00% 80.00% 70.00% 60.00% Duty Cycle 50.00% 40.00% 30.00% 20.00% 10.00% 0.00% 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 5.5 6 6.5 7 7.5 8 8.5 Time (Sec.)
