8086 Microprocessor Lab Environments 8086 Programming by Ravinder Nath Rajotiya - February 21, 2022February 21, 20220 Different ways to write 8086 Assembly Program Introduction The MPI Lab experiments can be performed using the microprocessor trainer kit or it can be performed using a PC installed with one of the different assembler available like MASM611, NASM, TASM and so on. It all depends on the instructor/faculty which one they prefer. The advantage with the trainer kit is that you can view the different ICs and other components on the kit, you can manually set certain settings using different jumpers/links on the motherboard and feel the concept of low level programming. You are required to first write the program on a coding sheet or notebook, then manually assemble it referring the mnemonic/hex code table and substituting the address all manually with
Interfacing Stepper Motor Microprocessor and Interfacing by Ravinder Nath Rajotiya - November 9, 2021November 11, 20210 Interfacing a stepper Motor Definition: These stepper motors are made of permanent magnet rotor with stator field excitation. Unlike the DC motors which move continuously, the stepper motors move in incremental steps. The stepper motor is a type of DC motor with the field placed on the rotor in the form of permanent magnets with two, three or four sets of coils called phases, placed in the stator around the rotor. Common step size of stepper motor is 0.9 to 30 degree. Applications Area: Robotics, printers, object handling, plotters, disk drives etc. Types of Stepper Motors: Stepper motor can be a two phase stepper or a four phase stepper motor. A two phase stepper motor has two stator poles whereas a four phase stepper motor has four

Stack and Subroutines in 8085 8085 Microprocessor by Ravinder Nath Rajotiya - October 13, 2021October 13, 20210 Stack and Subroutines Stack and subroutine are powerful mechanism in 8085 microprocessor for modularizing the assembly program, Stack A stack is a first in last out memory locations in the r/w memory and is used during the execution of a program. This memory is generally specified by the programmer in the main program. To point in the stack memory every processor has a pointer known as the stack pointer. To use the stack, the stack pointer is fist loaded with the beginning address of the stack memory by using the instruction LXI SP, XXXXh. Where XXXXh denotes a 16-bit memory address. The stack may grow up or down. In 8085 the stack grows downward in the reverse order, that means, that once the
