Hi,

No class this Wed., Oct 31!!!

I have posted HW #3.  It will be officially handed out on Wed. and due on
Nov. 14, but yes, you can get started right away.

First, you'll want to read Anderson & Shanley book as noted on HW #3
(chapters 1,2,17,18,19).

Second, meet with your group and work on a more detailed design to turn
in with HW #3 - i.e. your final design (you may edit it for your final
report, but my advice is get it done now so you canst staple it on
your final report in December).

Third, work on the ISR and PCI portions of the HW after you've read 
Shanley.

You'll want to read over intLib in the Ref manual and for PCI you should
look at code on the magellan system in $WIND_BASE/target/h/drv/pci and
$WIND_BASE/target/src/drv/pci

The HW is not too hard, but please take time to produce a good design and
read Anderson and Shanley carefully and review code and Ref. manual on
ISRs.

There is also example code for an x86 interrupt using lower-level intVecSet
and intVecGet functions - this will teach you a bit more about how the
vector table works on x86, but you may also use much simpler intConnect.

You may also want to look at btvid.c at the "probe" function in the example
code.

I will also post some lecture notes early this week on the "canonical form
of a VxWorks service".

After Nov. 14, we will have no homeworks at all and the focus will be solely
implementation and test of your projects, so make sure you are ready to
start integrating pieces, coding, soldering, etc. by then!

Watch e-mail for updates ...

Have a great Halloween!


Sam
