sure! the dragon12 is used at my university to learn embedded system
technology.

i actually learned embedded systems using the HC11 handyboard. if u want, i
can provide you with some documents/files that we use to learn some of the
functionalities of the HCS12 such as ATD, LCD, digital interfacing... etc..=
.

tell me specifically what you need and let me see if i can help you!

Hello,

I use Dragon12 in my class. Tell me what would you do with that board.
Maybe I can help you a bit.

Google will give you a lot of hits on "dragon12", including a lot of
college and university pages. Some include lesson plans and labs.

You need to decide if you want to teach assembler or C. I think most
colleges use assembler for a first course, and C if they have an
advanced course. But some start out with C.

I make some freeware open source IDEs (AsmIDE and EmbeddedGNU), but
the limited free version of CodeWarrior would work for your needs.

I'm hoping more colleges use the 9s12c32 devices in the future.
They're cheaper and you can get full debugging support without using a
BDM device, assuming your application doesn't need to use the serial
port. The AN2548 Serial Monitor gives students the ability to download
programs to flash, and they execute upon power-up. And the devices are
so cheap you don't have to apologize if you make students buy one.
Check out the Wytec DragonFly or the Technological Arts NanoCore12.

Or you can also re-program the Dragon12 with the AN2548 Serial Monitor
(in place of d-bug12) and you'd get the same benefits. The Dragon12
has 2 serial ports so you'd still have one free for the application to
use.

My Pluto debugger will be done within a couple weeks. It supports full
assembler debugging with the Serial Monitor. I'll add BDM and C
language support later.

I'd like to encourage you to go beyond simple d-bug12 EVB mode
debugging with a terminal emulator. This isn't the best option now. A
modern debugger will help students be more productive and it will help
them get excited, which can help them learn better.=20

The EPROT register is loaded from EEPROM array address =3D=20
top_EEPROM_address-2 during reset. If someone has programmed EEPROM=20
protection byte to nonFF then the only way to unprotect EEPROM is - use BDM=
=20
pod. Enter special mode, set EEPROT register to $FF and erase EEPROM=20
protection byte. Also you should verify that reserved EEPROM bytes are all=
=20
in erased state. Reserved bytes are top 16 bytes of EEPROM array minus one=
=20
EEPROM protection byte.

Edward
