Assembly - HCS12 assembly

Hi,
I am learning the assembly for the micro controller MC9S12C32 with the compile code warrior.

I would like to know if there someone that can help me. I have some problems with my codes.

I tried the list of website you suggested but I have not found something good for me.
Please let me know

Thank you

While I don't know who, if anyone, here knows much about that processor (I know a little), chances are that at least some of your questions will be general enough that we can give advice even if we don't have detailed knowledge about it. Whether we know the HCS12 or not, the main thing we'll need is some idea of the problem your having, including any specific code which you're having trouble with.

Also, could you tell us which SBC or embedded controller (or simulator thereof, more likely) you are targeting? The details of the other hardware will almost certainly be important, since the whole point of a micro-controller is, well, to control devices. Dealing with the CPU is probably less of an issue than dealing with the peripherals; the Freescale processors are rather simple beasts if memory serves, and while they have some weird quirks to them, they aren't that hard to learn to work with. Some of the single-board computer layouts based on them, on the other hand, seem to be designed to maximize frustration more than anything else.

Finally, have you ever done any assembly programming for any other CPU before? I'm assuming not, but if you have, it could help to know which processor and system it was for, as it would give some frame of reference from which to explain things. I know you know some C, so we may be able to use that as well, but the closer we can get to what you are actually doing the easier it is to explain new details.

That processor is based on the MC68000 ISA. That's pretty clear from the name, but a quick Google search verfied it (Feescaler's 68HC12 architecture). You should have no trouble finding references on programming a 68000 chip - its fairly easy to learn and there are free emulators to program against.

Hi,

thank you. I will come back soon. unfortunately, we shift to C language with the HCS12.
I found some goo references though for assembly instructions.
Thank you
