I need help, if somebody could point me to a detailed AXE guide it’d be much appreciated. However, I want to come here, as I am learning axe so I can learn ASM, to ask questions...
I am trying to install an interrupt, say perhaps if it finds that I press two certain buttons at one time, it immediately does some BCall of my choosing. Here is my code, why does it clear my ram?
:.INTERUPT
:Lbl ABC
:If getkey(random keycode I will find out later.)
:Asm(EF....
:fnInt(ABC,6

I’d also like to find out how to turn off the calc using AXE

1. your interrupt, from the code you posted, doesn't ever return. That's a large problem.
2. make sure, when you are using that inline assembly, that you write the called address to RST 28h little endian.

As for turning of the calculator, you would do it the same way as in assembly (and likely, you'll have to use inline assembly) -- turn off the LCD by sending $02 to port $10, and put the CPU into low power mode. And, of course, do the reverse to get out of that.

Finally, please don't call "Axe" in all uppercase. That's not it's name, and it's just kind of annoying that way.

I wasn’t sure, Ash. But thanks. Tell me how to return...?

Code:

Ingenious.

where exactly though?

At the end of the code intended to be an interrupt.

Just to clarify Dapianokid, is your intention to write a program that creates an interrupt that persists after the program has finished executing? I ask because of the peculiar placement of FnInt() in your program, as it is *inside* the interrupt. FnInt() should be placed at the beginning of your program, and is the initialization needed in order for the interrupt to function. Interrupts also need to be reset before the program terminates with LnReg, as Axe interrupts do not work correctly after the program ends. An example program using interrupts might look something like this:

Code:


This program first initializes the interrupts with the FnInt() line. From then on, the subroutine is called at regular intervals by the interrupt system. After your program is finished, interrupts are reset with LnReg, and the program returns.

You double-posted within 28 seconds of yourself. This is not a text message nor an IM client, it's a forum. Don't do that again.

Builderboy, in this case, the program does persist? I am still extremely new to Z80 assembly as well as Axe. I like your usage of examples, and much needed pointers, as though I had no idea what I was doing. Because I wasn’t. Over the course of one schoolday, I tend to get anywhere between thirty and fifty RAM clears and three or four AppVars and Archived Programs clears just to get one bit of syntax I wanted right. It’d not the best environment for trial and error.

Sorry, Kerm, the forums I’m used to take double posts and turn them into one post... won’t happen again. >:|

Please don't do that again.
