8085 Assembly language programming code for beginners
 
Addition of two 8 bit numbers.
Code:

  MVI B, 06
  //Load Register B with the Hex value 06
  MOV A, B
  //Move the value in B to the Accumulator or register A
  MVI C, 07
  //Load the Register C with the second number 07
  ADD C
  //Add the content of the Accumulator to the Register C
  STA 8200
  //Store the output at a memory location e.g. 8200
  HLT
  //Stop the program execution

Addition of two 8 bit numbers stored in memory
Code:

  LDA 8500
  //Load the accumulator with the address of memory viz 8500
  MOV B, A
  Move the accumulator value to the register B
  LDA 8501
  //Load the accumulator with the address of memory viz 8501
  ADD B
  //Add the content of the Accumulator to the Register B
  STA 8502
  //Store the output at a memory location e.g. 8502
  HLT
  //Stop the program execution

Addition of two 8 bit numbers stored in memory and storing the carry
Code:

  LDA 8500
  //Load the accumulator with the address of memory viz 8500
  MOV B, A
  Move the accumulator value to the register B
  LDA 8501
  //Load the accumulator with the address of memory viz 8501
  ADD B
  //Add the content of the Accumulator to the Register B
  STA 8502
  //Store the output at a memory location e.g. 8502
  MVI A, 00
  //clear the accumulator with 00
  ADC A
  //Add with carry the content of the accumulator
  STA 8503
  //Store the output at a memory location e.g. 8503
  HLT
  //Stop the program execution

Implementing the above program for the subtraction is very simple just replace ADD with SUB and ADC with SBB and all should be working fine.

I would suggest you couple of things.

1. Dont jump into some thread without any context as that will take longer for you to make someone understand what you are looking for.
2. We are not here to complete your assignments but its you who need to be doing that. Its just that we can assist you.

Also Please go through this.

I have an assignment to do, inwhich i have to initiate a time delay of n-seconds. I don not know how to start.
Do I initiate the internal clock to start counting? If so, how? I heard something about typing n clock.com, in the assembly line but i am not sure.

And how do I know which inputs the clock signal is coming into?

Write a program for 8085 to count numbers with even parity among fifty numbers stored in memory

starting at 8600H and store the result at the end of the memory.

CAN ANYONE solve this problem ?its very urgent..

Rearranging Bytes
16 bytes are residing in locations starting from 2400H. Transfer those bytes in locations starting from 2500H in such a way that 1st 8 bytes in the 1st block should appear at last 8 locations of the 2nd block and the last 8 bytes in the 1st block at 1st 8 locations of the 2nd block.

Checking bits of a word.
A word is residing in location 2400H. Write a program to check each bit of the word starting from MSB and fill 16 locations starting from 2500H, with either OOH or FFH depending on the bit, FFH if the bit is 1 and 00H if the bit is 0 . Also count the no. of 1s and 0s (in BCD) in the word and store them respectively at 2600H and 2601H.

Write a program to fill up 128 locations starting from 2400H with bytes in the following pattern: 1st 64 location to be filled up as 00H, 11H, 22H, . FFH, 00H, 11H, 22H and so on and the last 64 locations to be filled up as FFH, EEH, DDH, OOH, FFH, EEH and so on.

Re: 8085 Assembly language programming code for beginners
 
Write program in Assembly language which accepts two decimal digits from
its user, prints a new line on the display
screen, and if the first digit is larger than the second, displays the
average of the two digits (to the
nearest whole number) and otherwise displays the square root of the
product of the two digits (to
the nearest whole number). Then the program should return to DOS control.
Thus, if the user types
93
then the program displays
6
and if the user types
39
then the program displays
5
Hint: Think of easier way for square root calculation

Re: 8085 Assembly language programming code for beginners
 
When we declare a variable like

var dw 92F3h its OK, but if we write it like
var dw B2F3, it gives an overflow error. Now to overcome this, we need to give a 0 before it.

var dw 0B2F3h. Now this works.

My question is why in certain cases we have to give the 0 ?

to estimate the size of the block and store the count in BCD in COUNT.
 
39.A block starts at 0C20H and ends where 4 consecutive 00H are followed by FFH. Write a program to estimate the size of the block and store the count in BCD in COUNT.

Write a program to fill 6410 locations with nos. as shown below: 1st 4 locations with 0FH
2nd 4 locations with 0EH
3rd 4 locations with 0DH
last 4 locations with 00H
and repeat the same till all locations are fully filled.

Re: 8085 Assembly language programming code for beginners
 
58. Two blocks of bytes exist in 0C20H and 0C40H. When the interrupt 6. 5 key is pressed, for each pressing the larger of 1st bytes of each block is to be written in location 0C60H. Each block consists of 10 bytes and hence after 10 interrupts a new block shall exist in OC60H with larger bytes of the two blocks. Disable the interrupt after the new block formation.
