Microprocessor and Microcontroller Lab Programs | All in One

1] Design and develop an assembly language program to search a key element ‘X’ in a list of ‘n’ 16-bit numbers. Adopt a binary search algorithm in your program for searching.

3] Develop an assembly language program to reverse a given string and verify whether it is a palindrome or not. Display the appropriate message

Checkout

4] Develop an assembly language program to compute nCr using the recursive procedure. Assume that ‘n’ and ‘r’ are non-negative integers.

5] Design and develop an assembly language program to read the current time and date from the system and display it in the standard format on the screen

Checkout

6] To write and simulate ARM assembly language programs for data transfer, arithmetic and logical operators (Demonstrate with the help of a suitable program)

Checkout

7] To write and simulate c programs for ARM microprocessor using KEIL( demonstrate with the help of suitable program) Note: To use KEIL one may refer to the book: Insider’s guide to the ARM7 based microcontrollers, Hitex Ltd, 1st edition, 2005

• a] Design and develop an assembly program to demontrate BCD up-down counter (00-99) on the logic controller interface.
• b] Design and develop an assembly program to read the status of two 8-bit inputs ( X & Y ) from the logic controller interface and display X*Y

9] Design and devlop an assembly program to display messages ‘FIRE’ and ‘HELP’ alternately with flickering effects on a 7-segment display interface for a suitable period of time. Ensure a flashing rate that makes it easy to read both the messages( Examiner does not specify these delay values nor is it necessary for the student to compute these values).

Checkout

10] Design and develop an assembly program to drive a stepper motor interface and rotate the moto in the specified direction(clockwise or counter-clockwise) by N steps ( direction and N are specified by the examiner). Introduce suitable delay between successive steps. (Any arbitrary value may be assumed by the student).

Checkout

11] Design and develop an assembly language program to

• a] Generate the sine wave using DAC interface ( the output of the DAC is to be displayed on t he CRO)
• b] Generate a half rectified sine waveform using the DAC interface. ( The output of the DAC is to be displayed on the CRO)
