SofTec PKHCS12C32
Started by ●April 18, 2005
Hi All
I just recently started with HCS12 and this weekend I decided to use
it on a little project. I need to generate a 250uS pulse every 250mS.
So I modified the example program RTI that came with the Kit, I
changed the RTI prescale and modify the rest of the program to
toggle
PORTB bit 0. the program worked great... Then as I was going to add
more functionality to the program I decided to create a new Project.
I created the project using the wizard in CodeWarrior and set the
target to SoftTec, then I copied the contents of the main.c from the
modified RTI program and pasted it into main.c of my new project.
The problem is that my new project will not debug, there are no
errors
but when I tell it to debug it starts and then stops with
message "unknown event", is almost like it is stepping.
I tried the same with the ADC program and that one works no problem,
so I can only think it is something to do with using the RTI when on
BDM mode...
Can someone guide me on the right direction.
thanks
Luis

Hi Luis,
please make sure that you have correctly declared the interrupt
routines either in the main.c and in the default .prm file of your
project. If I was you I'd disable all the interrupts and try to run
your code, just to see if it works.
Regards,
Nicola

Hi Nicola
Thank you very much, that did the job. When I compared the
SofTec_linker.prm files on both projects the one I created was
missing "Vector 7 RTI_ISR" which defines the interrupt vector for
the RTI. Is this the place that you normal define it ?
best regards

Yes Luis,
usually the .prm file in CodeWarrior is used to define memory
sections (ROM, RAM, etc.) and interrupt vectors. You will find more
information about that in the Metrowerks CW12 help files (search
the "How To Initialize the Vector Table" paragraph).

Nicola
