Motorola's 6811 Microcontroller family
LDG wrote (at 199705):
Don't know if you've seen our page recently, but we've upgraded our site
with new descriptions and more photos.
We have also lowered some of our prices.
The SBC-2 now goes for $49 ($10 off) and the SBC-8K has had an 8K
Serial EEPROM added at no extra charge (was $10).

Also, it's worth trying to find a copy of "M68HC11 HCMOS* Single-Chip
Microcomputer Programmer's Reference Manual" (M68HC11PM/AD, Otherwise
known as the "Green Book". I haven't seen a new one of these in years
but it is a valuable resource for programmers. In addition to an
instruction-by-instruction listing it has very useful discussions of
addressing modes, and has numereous handy summary tables of instructions,
op codes, etc.

- It cost $66.00 + tax but I think its worth it.
- This book starts with basics and goes into intermediate to slightly advanced programming.
- It has some excellent examples of interfacing the microcontroller
with peripheral circuits for various uses.

Advantages:
- Price is right
- You get the source
- Complete ANSI compiler (including varargs support)
- Pretty good optimizer
- Also includes a cross-linker with support for libraries (part of asxxxx)
Disadvantages:
- No support.
- You have to roll your own crt0.s (but a sample one is includes in the minilib distribution).
- Current incarnation is Unix-only (but should work under any Unix system).
- Uses a pseudo-register scheme which isn't as efficient as it could be.

Don't wait anymore, UMPS is really what you need, it simulates any
of these micros and fast, very fast.
Do you need to see if your I2C program or your LCD protocol is OK?
UMPS can simulate I2C peripherals, LCD panels, LED's, push-buttons etc.

Ahhh, excellent info, I was just getting a new (Non EVM) system up
and going last weekend using the buffalo monitor.
My S19 file was ORG'ed to start the code at 4000h, but the byte was
always being cleared!!!. I had no idea what was going on.
Thanks again for this valuable tip.

Subject: Some info on the MSCC11
Here's some info on the MSCC11: A Single Chip MC68HC11 Microcontroller.
The MSCC11 features an MC68HC11 processor mounted in a 52-pin PLCC with headers
connected to the processor ports. The MSCC11 realizes a single chip
microcontroller and provides
o Eight 3-wire (5 volts, ground, signal) powered analog or digital input header
connected to Port_E,
o Eight 3-wire powered digital output header connected to Port_B,
o Eight 3-wire powered bidirectional digital signal header connected to Port_C,
o Jumpers to separate unregulated and regulated power and ground rails on the
headers.
o The power rail can drive up to 16 servos attached to Port_C and Port_B
headers
o The regulated voltage rail always drives the microcontroller and the eight
powered digital/analog inputs attached to Port_E.
o Eight 3-wire powered analog sensor connectors may be attached directly to
Port_E.
o A 5-pin male header permits the MSCCB11 to serially communicate with other
MSCCB11s or personal using the Mekatronix Bidirectional Serial Communications
Board (MBSCB) described below.
This is extremely high-quality!

I wrote IDE11 (and still developing V2.3). BTW: Feel free to get a fully
functional eval copy of IDE11 at members.aol.com/mctgbr ! (V2.3 will
be available in the beginning of June). Any comments are welcome!
The 7812 Bd solution was already explained here by a number of people (good
work folks ;-) !), so I don't have something to add. I also use 7680 Bd
instead of 7812. This never has been a problem (in DOS).

Subject: EVBoard
We use our own EVB in our school. It can be purchased directly. However, as we
finished the Windows Version of our Software, we consider giving away the dos
version for free.
It is a full functional embedded environment, that looks like Turbo Pascal:
* Text Editor
* Download Function
* Terminal Shell
* Pascal Compiler
- Our EVB comes with a free ware assembler (asmhc11) but works w/ any Assembler
that may be called by a Batch file.
- The EVB comes w/ 32kB Memory and 16kB Rom that provides many functions such as
RS232* Support, c-like write function and a Shell where new commands may be added.
You can have a look at 206.215.185.199/lemps/lemps.html
Unfortunately, at this point, the documentation is German only.
If enough people are interested in our product, I would translate the Doc for the
American Market.

If a German book would be helpful for you I recommend the following title

Subject: HC11 boards
Here's another board you probably haven't heard of yet... We have just
released our new 32K HC11 ModCon board! It is low cost, and completely
expandable. The stackable connectors provide access to all HC11 pins, and
are pin compatible with the EVBU boards (using a split cable). We will also
be producing a proto-board that will mate with the ModCon.
The ModCon has many built in features to make it as versatile as possible;
It supports both the DS1233 or MC34064 reset chips. The four servo
connectors can be configured for both Airtronics and Futaba standards. Four
dip switches support all of the HC11's modes and Buffalo functions. There is
a cut-trace option for battery support for the RAM. The 14 pin SPI connector
has additional lines to support many types of peripherals.
We sell a the ModCon in a 'minimal' configuration (without RAM or stacking
connectors) for $87.00. The other components can be added later. Or the
complete ModCon Kit can be had for $137.00. Assembly is $20 extra.
Our web site has a number of photos, and details, although we will continue
to add information. Next up, I'm going to have all the connector pinouts up.
If the site leaves any unanswered questions, please let me know!

Motorola provides a web site dedicated to providing design information for
the HC11 processors. The address is:
www.mcu.motsps.com/hc11/home.html
Browse around a bit (in the literature section) and you'll find a place
where you can download PDF files of all the information you need. Look for
two items in particular: The "M68HC11 Reference Manual", part #
M68HC11RM/AD. This manual, available in PDF form, contains a complete,
detailed description of the instruction set. You will often hear people on
this list refer to this book as "The Pink Book" since the printed hardcopy
version of this manual has a marbled pink cover. You should also look for
the Technical Data manual for the particular part you are interested in
working with. There are several versions of the Tech Data manual, one for
each major HC11 series part. For example, the book that covers the
MC68HC11E9 and all E-series parts is entitled "M68HC11 E Series Technical
Data", part # MC68HC11E/D. The Tech Data books cover the usage of the
on-chip subsystems of specific HC11 parts in greater detail than the
treatment provided in the "Pink Book".
If you are patient, you can also use the web-based tools at the
aforementioned site to order literature to be mailed to you directly. The
form provided for this purpose expects Motorola document numbers, which I
have included above. These doc numbers are also provided on the page that
lists PDF files available for download. One drawback of this service is
that Motorola typically will not mail hardcopy documentation outside North
America.
Good luck in your work with the HC11. If you have difficulties, don't
hesitate to post your questions here - there are a lot of good people on
this list who will most likely be willing to help you "get your feet wet".
