 Lab #2: UF 68HC12 Board Construction & Software Tools 
 
   
Purpose 
 
In this lab you will begin building your 68HC12 
Development Board and then step through 
example 6812 code using our shareware software 
development tools.  Your TAs will provide more 
information about these tools. 
 
In-Lab Board Construction 
 
Begin or finish (depending on when you started) 
soldering the components on your 68HC12 
Development Board.  Upon completion, look for 
poor solder joints and fix them when necessary.   
Also let your TA perform a visual inspection of 
your work.  Next, place the components found in 
your kit into their proper sockets on the board.  
 
 
Assembling, Linking & Simulating 
Microprocessor Code (TA Responsibilities) 
 
Your TA will now perform the following tasks 
to briefly demonstrate the tools you will be using 
in the upcoming labs.  It is important to record 
(and keep) file names, web address and other 
information for future use. 
 
1. Download the short example program that was 
written to execute on the Motorola 68HC12 
microprocessor.  Briefly talk about the code and 
physically show students an example of a 
microprocessor IC. 
 
2. Download the Mini IDE assembler and install 
on the host PC. 
 
3. Illustrate how to assemble the example code 
and briefly look at the files produced (list and s-
record). 
 
4. Download the HC12 Simulator and Java plug-
in for MS Internet Explorer and Netscape 
browsers. 
 
5. Install both items and show how to load the s-
record output produced from the assembler.   
 
6. Briefly step through the code and explain the 
purpose of the simulator. 
 
7. Field questions from the students. 
 
8. Remove all installed software and allow 
students who do not have extensive experience 
installing software attempt steps 1-5 by 
themselves.  Help them as needed. 
 
 
 
 
TA Note: It is suggested that while some 
students are soldering their boards, others can 
begin experimenting with the new software tools 
on the PCs in our lab.
