Sample Problems

The first link is just the problems and the second link is the problem with the answers. Try doing them on your own first and then check the answers. These are topics for the first exam but some are little trickier than what I would put on the exam itself.

The M68HC11 Simulator and Assembler

The following files are provided for EE265 and EE567. They are password protected. I will give the password to current (sp 10) 265 students in class.

Here is basic information how to load a copy on your own machine:

1. Download the two files in a directory in which you plan to keep the simulator.

2. Unzip the two files.

3. Run setup

Installing this program on the 64 bit version of Vista or windows 7 requires some additional info we will give in class.

An issue seen on the simulator/assemblers in the student labs

Some but not all machines in the public PC labs have a problem with their default memory map settings.

If as soon as you assemble your code you get a message about the INIT vector, then you are having this problem.

One way to check this problem is to type MAP in the commands window. The first line should be "$0000 up to and including $00FF RAM."

More later.
