- Using assembly language write a code that controls a stepper Motor from a parallel port using a pc(please include the input and output address). The direction of the stepper is controlled by the mouse. Left-click for clockwise and right-click for anticlockwise.The speed of the motor is controlled by the keyboard and has 8 different speeds 0-7.

The first LED will flash on and off at a rate determined by you– just ensure that it is a reasonable rate so its not too quick to see or too slow that you fall asleep waiting for a change. The second LED will flash on and off at twice the rate of the first LED, and the third LED will flash on and off at three times the rate of the first LED. //I would love if someone could help in in making the psoc coding thanksarrow_forwardWhat exactly is "clocking," and why do you need to configure it?arrow_forward
- 4) Write an assembly program that turns on the LED as soon as BTNO is pressed and turns it off as soon as it is released. The program must also use TIMERO timer to measure the duration of pressing the button and print this duration in milliseconds in the terminal window upon the button release. The program must be capable to measure the duration up to 100 seconds. Make sure to process GPIO and TIMERO hardware interrupts by using interrupt handlers and NVIC, so no flags polling.arrow_forwardIf the keyboard interrupt enable bit is set then the keyboard will interrupt the processor each time a key is pressed. Write a simple interrupt handler that returns the character pressed in register $v0. Rewrite the main function of question 6 using keyboard interrupts.arrow_forwardComputer Science - Assembly language code: Q1. A) A microprocessor is wired into a sensing control circuit so that the memory locations 42 and 43 each contain the values 0 or 1. Memory location 50 is connected to a light switch. When the value in 50 is 1 the light is on and when it is 0 the light is off. Write a program to switch on the light on when the values in locations 42 and 43 are both 1, and to switch off the light when the values in locations 42 and 43 are both 0. Only use the ARM assembly language instructions, MOV, JMP and JNZ. Assume that the MOV instruction updates the flags with the status register.arrow_forward
