The $99.00 EVBplus2 68HC11 JR trainer (code name: FOX11) is
specially designed for students in the classroom environment.
Many colleges require students to buy their own trainers, so students can work off-campus and school is not responsible for maintenance of the trainers. In addition, this reduces lab manager's workload. It's a great idea, but the only problem is the cost because students first have to buy textbooks before buying trainers. Our EVBplus2 board is well received by many universities around the world as a piece of lab equipment, but some professors would like to have a $99.00 EVBplus2 board available before making their students buy their own trainers. That's precisely the reason the FOX11 has been born.
The FOX11 board combines and caters to many professors' ideas and suggestions, so it easily meets or exceeds the requirements of their courses and lab assignments. We have chosen one board approach instead of a modular approach for reliability and low cost. Although modular approach has its own merits, it is more suitable for extracurricular activities by more experienced users who have more trouble-shooting ability, such as a robot controller application.
When a board has more mechanic connections, then it will have less reliability. For a student, as a beginner, the course itself is already too hard to finish in a short semester, so why should he or she be responsible for trouble-shooting any unnecessary problems caused by more mechanical connections? Also, if you add all modules together to duplicate the functions that the FOX11 board offers, it will be way over your budget. Our trainer is not only a one-piece approach, but also is a perfectly sized board for a trainer. You need a small board, which does not occupy too much space on the bench. At the same time, it cannot be too small and without much weight. For example, if you move the RS232 cable a little bit accidentally, your whole project could move chaotically, even flipping everything over if the board is very small. You are quite lucky if you don't burn anything.
The
goal of the FOX11 trainer is to cover 5 most important hardware elements in the
68HC11 for educational purpose and also keep it affordable.
The 5 components namely SCI, SPI, Timer, ADC and external memory interface that
are very important subjects for students to learn are all covered by our FOX11
board.
On our FOX11 board, it has:
1.
Two RS232 ports with independent baud rates, one is for development work, the
other one is for user SCI application.
Beware that Most EVB/EVBU boards only have a RS232 port.
Image how hard to debug your code if your application uses the SCI of
68HC11? What if your application needs a higher baud rate? It’s impossible to
do it with only one RS232 port.
2. A SPI header for communicating your external SPI device,
such as LED, LCD, relay and I/O expansion boards.
3. Eight LED indicators can be used for monitoring pulses that
are generated by timers. An on-board speaker can produce music or other
waveforms via timer system
4. A potentiometer can be used to adjust input voltage of an
Analog to Digital Converter channel.
Today a trainer without ADC does
not deserve a place in classroom including a 68HC11D0, or 68HC11D1 based
trainer.
5. A 40 pin female socket provides all address, data and
control signals for connecting external memory or I/O devices to learn 68HC11
memory interface in expanded mode.
This is a very important fundamental subject where the 68HC11 shines
comparing to other microcontrollers.
A female socket is easier than a male header for student connect signals
to an external memory or I/O chip on the breadboard via jumper wires.
There
is no such trainer with above features and also has 32K RAM, 32K EEPROM, 32K
EPROM and a large solderless breadboard for $99.00 on the market
today. The hardware is only a part of system.
The FOX11 board comes with 3 built-in monitors for different
teaching methods. They
are all pre-installed in an on-chip EPROM. The BUFFALO monitor is the default monitor, meaning the
board will start up with BUFFALO monitor. In BUFFALO monitor mode, a
professor does not have to change his teaching materials and lab
assignments. It works just like a regular Motorola EVB/EVBU board but
with a lot more on-board peripherals. In Wytec Monitor mode, it will
allow symbolic debugging, data watch, and many unique features that
will surprise you. In Metrowerks monitor mode, it works with Code
Warrior IDE for C source level debugging. It will also support other
3rd party compilers and C source level debugging, such as Cosmic C,
GNU, ICC, Interactive C and NoICE.
If you are not a student, you should understand that $139.00 is still a much better value comparing to other boards on the market today. The best price you can get a board that has 2 RS232 ports from other manufacturers is $190.00. $99.00 is just above our cost, when you pay $139.00 you actually support us to provide discount for educational purpose, a very good cause. Software producers can offer freeware. We, a hardware manufacturer, cannot offer free hardware because we have to cover our manufacturing cost. But when we price it just above our cost, we are almost offering a free service to students for a good cause.
The price includes 32K RAM, 32K EPROM, 32K EEPROM, a large solderless breadboard, a 6 foot RS232 cable, a CD and a 110V AC adapter ( US, Mexico and Canada orders only)
With a 4x4 keypad and a 16x2 LCD display module, the FOX11 board is a complete development system at a very reasonable price. It is only possible because it is made by Wytec, a company known for making quality products at low prices.
We support the Motorola University Program. If you are a professor in the USA and Canada, teaching a 68HC11 course, and you have already or about to have your students buy a training board, please email us a request. We will be more than happy to supply you a demo board for a 60-day free trial without any obligations.
Ironically, we are probably the only company in the world offering a true University Program for Motorola in a fairly large scale, even Motorola University Program does not offer you a 68HC11/HC12 demo board. Motorola does not make a 68HC11 EVB/EVBU any more, but they sell their MC9S12DP256 EVB board with a BDM for $495. Some professors told us that they have evaluated many development boards and found that nobody even comes up close to ours in terms of value. We offer a great value to you, but we do not receive any help from Motorola and this program is totally supported by our owner's advocacy of the 68HC11/12 families since 1987.
