Student needing help

Started by racinilodge October 21, 2004

Hello, my name is mike, and in january I will be taking a course on
the 68hc11. I was hoping to get a handle on it before i head back to
school. If anyone can direct me to anywhere i can go to get
understand the workings of the hc11, mostly the assemby directives,
and where beginners can go to possible do some simple simulation
programs that would be great. I have a copy of the hc11 reference
manual and have skimmed through it, but alot of the info is either
over my head, or i find doesnt give enough detail. I'm looking for
a "writing hc11 programs for dummies: sorta thing.

thanks alot

Mike

Keep reading the HC11 Reference until you understand how things work. Read,
don't skim through it. There are no shortcuts in education. 'Read and try it
out' in an endless loop.

Assembler directives differ among assemblers. They are not directly related to
the HC11. Did you mean the assembly language mnemonics? These should be in the
HC11 Reference. First step is to understand the hardware, then if you've done
any programming, it should be relatively easy to cope.

If you're completely new to hardware architecture maybe you wait for your course
to begin. If you're also new to programming maybe you should take another
course first.

Free simulators are plenty. My preference is Shadow11 (and not because it uses
my assembler). It is the closest thing to the true development cycle (edit,
assemble, simulate) from a single program. It has the feel of high-level
language debugging tools. It's not very good at simulating all peripherals but
I think you're currently interested in the language, and for that, it's best.

Check out all the examples and tutorials at technologicalarts.com. They also
have an hc11 webring


While you are at it, read up on the HC12. It is the modern upgrade for the about out of date HC11. The HC12 has a very similar architecture and instuction set but also has additional instructions and peripherals which modernize the processor. I is also much better equiped to handle high level languages such as C.

Then you can impress your professor with your knowledge. Maybe even get him to upgrade into the 21st century.
