ChibiAkumas ASM Programming Forum

Thanks for the correction on BC. So BC is used for ByteCount when used with LDIR and B is used on it's own as a loop count with DJNZ. Some really weird head scratchers whilst working with assembly. This is my first time trying to work with it. It's nothing like the other languages i know (PHP, MYSQL...

Hi hi, I'm trying to understand what each register in the z80 does and how it can be used. I made the following table and wondered if anyone could point out any errors/or updates that could be made to it. Label Size (bit) Note A 8 Accumulator. Used for all the calculations. (can be used with F) F 8 ...

Thanks for checking that over. I'll continue the videos and hopefully I understand enough to start making my own programs eventually.

Hi, I was getting a bit confised because of the use of a b and c being used in BASIC and asm. So i've written this out and changed the BASIC to VAL1 VAL2 and FUNCT instead of a,b and c. I've also written out how i've interperited the asm code. Have I got it correct? I'm not too sure about the MathDi...

Many thanks for confirming. Slowly but surely I'm getting there. I wrote my first 'complicated' BASIC program last week, so i'm hoping to convert it into ASM + BASIC to make it run a bit faster. Then i'm hoping to make it look much better and easier to use. i.e. just using the arrow keys on the keyb...

Hi hi, I've been going over these first video's again and I have a question about the LDIR command. When using it in the small program you made in this video: org &8000 - we're setting the location of the program ld hl,&0000 - we're loading &0000 as the source address (beginning of RAM(?...

I've been looking into Ben Eaters 8-bit breadboard computer. So far i've made the CPU clock and thats it haha!

Hi all, For a change that "sunny Scotland" isn't sarcasm as it is actually sunny here today. Anyhoo. I'm here in the hopes to share my learning of z80 ASM (and maybe some more once i've managed to make a few things for that) and ask questions when I get stuck, which (I foresee) will be fre...
