Ok, I'm a noob

Cool I started a tutorial a long time ago (that I never finished). It had a similar style, but it was aimed at BASIC programmer learning to program in hex/assembly. Here is an example from it:

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

------------------------------------------------------------------- Experiment 4  Memory Editing (v.1) ------------------------------------------------------------------- 214093 ;ld hl,plotSScreen ;9340h is the address* of the graph screen buffer* 3EAA ;ld a,$AA ;$AA→a Feel free to change the "AA" 77 ;ld (hl),a ;a→(hl) This stores the value of "a" to the address at "hl" 23 ;inc hl ;hl+1→hl 77 ;ld (hl),a ;same as before C9 ;ret ;Stop To Use: Simply run the program. This will edit the top left corner of the graph screen. Explanations:  Address- People can send you mail from anywhere because they know your address. Your address tells where you are. Similarly, in assembly, an address tells where each byte of memory is. Using a hex number between 8000h and FFFFh will give you access to the RAM (which can be edited). This is the address. It just so happens that the graph screen has all of its data stored at address 9340h There are 768 bytes of data for the screen and 768=0300h. So plotSScreen (Plot Save Screen) is 9340h to 963Fh. Whenever you see (), whatever is inside the parentheses is the address. If you see:         ld (xx),y "y" is being stored at address "xx" and if you see this:         ld y,(xx) Then the value at address "xx" is stored to y PlotSScreen-The way the data is set up is that each byte is 8 pixels. If the value is 3Eh, then in binary it is 00111110. All of the 1's are dark pixels and all of the 0's are light pixels. These are stored in rows, so there are 12 bytes per row (96/8=12). With 64 rows, there is 768 bytes in plotSScreen (12*64=768).

That is the most complicated one out of the four sections finished (I planned to have 25 to 50, but then I never finished).

Ok, you should really finish that tutorial, or give me all you have untill now

[stevon8ter]

I'm really meaning it, you should finish it, it's explicated very very well.
I'm leaving tommorow on vacation so I won't be able to answer on this topic (and others) for about a week and a half.

Okay, next week I don't have much work, so I can try Thank you!

[stevon8ter]

Ok first i wanna apologise for being offline much to long

Second: are u making any progresses on the tutotial, just asking, don't need it really soon so take it easy

Third: is there an ipod app to create and test asm progs?

Sorry, I haven't had much time at all to work on this stuff
