Hi eneryone,
Im trying to learn about assemply 8085 in order to make a project i have.
First of all which emulator to use? I work in linux and I currently istalled GNUSim8085.
Also, maybe somewhere I can find some simple examples?
The project is about making an array saved in specific places in the memory with specific number in it. So i started with learning the loop for. I tried, with my little MIPS experience to assemply this C code:
my effort is this code:
But i get errors in line 3. Anyway if anyone can help me please do so. I'm willing to learn and search with some help. Thanks.
Ps: What about gcc -S example.c ? What type of code i get in example.s?
I found something with some help...
This:
makes this code:
and the array is saved in memory at 0100H - 0109H.
That's the first part completed. Now i have to do the equation n=i^2-1 (i from the for loop) in order to save n in every row of my array.
Any help appreciated!

A first idea is to add i with itself at a loop and then decrease the result with dcr.
But i have problems with the coding part.. Anyone ?

As the 8085 doesnt have a multiply instruction you will have to add i to itself i times every time you go throgh the loop...here is a sample routine when i==3...

With Virtual 8085 I get 2 errors.
line 2: only 8-bit second operand.
I changed that with:
line 7: Invalid register specified.
Ok, i think that do the job!
Thanks for your help !
