Hi Markus,

Ask your neighbourhood librarian. As a patron you

may request titles through the BC interlibrary loan service.

University, college, and polytechnic libraries are members.

Good luck.

Hi Markus,
If you have access to a university library (or access to a student who can borrow them on your behalf), I'd try that. SFU has a decent selection.

markuslampert

lol - I was afraid that question would be raised ;).

It actually doesn't matter to me, I start from scratch with both of them. I bought this book from CircuitCellar on how design a microprocessor in Verilog (http://circuitcellar.com/editorsblog/microprocessor-design-using-verilog-hdl/). One of the things that is not covered in as much depth as I would like is .... Verilog.

If anybody can convince me that "the book might be nice but VHDL is the way to go", I will probably switch. I checked, VHDL books are as elusive and expensive as Verilog HDL books, doesn't make a difference from that perspective.

So ... if anyone
has any real arguments for one or the other, I would like to hear about it.

jnagy_y

Initially I wanted to settle with VHDL but I quickly realized that I had to study both. Opencores.org have some great projects but some are written in Verilog. For now I just want to code (cut & paste) PWM to control motor speed and read encoders. Later add SPI so I can talk to an external micro or add it to Nios and run the whole thing on an FPGA. Short term goal is to create a closed loop miniature pager motor control. The speed reduction (1:100) will be done on a mini cycloid drive. I started to machine the parts for my cycloid drive already the parts are looking nice but some pieces are still missing before I actually try the whole thing.

James

Hi folks,

Spring has arrived and with it the annual Linuxfest Northwest in Bellingham
Washington. This year it will be held on the last weekend of April, the 28th and
29th, 9:30am - 5:00pm.

http://linuxfestnorthwest.org/

For those who've never been, LFNW is a small con, but as good as it gets here in
Cascadia. There's a large room of vendors booths, several tracks of lectures, a
great raffle, and an excellent party on Saturday night from 6:00 - 11:00pm.

Vendors: http://linuxfestnorthwest.org/sponsors

Lectures: Final Tracks TBA ~April 15.
          http://linuxfestnorthwest.org/program/sessions

Party: http://linuxfestnorthwest.org/information/food

Accommodations:  http://linuxfestnorthwest.org/information/hotels

Transportation from Vancouver is either by car, by bus or by train.
If you're planning to drive, please consider car pooling. If you're looking to
catch a lift please expect to contribute some gas money.
Use this mailing list to assist with arrangements.

Driving: http://linuxfestnorthwest.org/information/travel

Another excellent means of getting to Bellingham is by ViaRail/Amtrak. Train
number 513 runs daily from the Vancouver train station leaving at 6:40am. Arrive
early for ticket purchase. It's about a two hour trip and costs $14.00 one way,
$28.00 return. For an additional $5.00 each way you can bring a bike and save on
taxi fees which can be high. Train number 516 returns to Vancouver leaving
Bellingham at 9:00pm which is plenty of time to put in an appearance at the
party.

Schedule: http://www.amtrakcascades.com/images/Amtrak_W32.pdf

Tickets: http://www.amtrak.com/servlet/ContentServer?pagename=Amtrak/HomePage

One final note, be sure to bring along a few Yankee dollars. You can get screwed
on the exchange rate and the food vendors at the college don't accept Canadian
currency.

So who's up for a little holiday?

Hi Mike,

This project looks interesting. Unfortunately that video clip doesn't offer much
detail, but here is what I worked out:

1. claws / knives - looks like they were carved out of plastic or expanded PVC
(something like Sintra) or hobby plywood

2. horizontal slide - something from a kitchen drawer?

3. horizontal movement - rack and pinion w/ a small motor? linear servo?

4. electronics - looks like just a simple two-button control panel, probably
uses an h-bridge to switch directions

If you want really cheap and local, look in hobby stores for some of the plastic
Tamiya toys that have motors, gears, etc. Ditto for Sintra or plywood. An even
cheaper option is to look at some of the parts you could get out of printers and
floppy drives.

Hi Mike,

Well, you didn't specify which part you wanted help with! :)

H-bridge is a circuit that allows you to apply reverse voltage to a motor without actually rewriting it. L293 is a very common chip to do this, will run a motor up to 600ma. Stack them to get more current (current needs depends on the motor you use). Beefier chips are available, L298 is quite common too.

Thy just sounds way over my head I just want to make it go forward and back using a switch be it two buttons or a dbdt switch as for programming and chips and everything well beyond me. I was thinking of getting a toy motor using some double a batteries and a switch of some sort to get forward and back motion. If that makes sense is it possible?

Hi Mike,

This project looks interesting. Unfortunately that video clip doesn't offer much detail, but here is what I worked out:

1. claws / knives - looks like they were carved out of plastic or expanded PVC (something like Sintra) or hobby plywood

2. horizontal slide - something from a kitchen drawer?

3. horizontal movement - rack and pinion w/ a small motor? linear servo?

4. electronics - looks like just a simple two-button control panel, probably uses an h-bridge to switch directions

Have you ever watched how a train converts linear energy to rotational energy?

http://upload.wikimedia.org/wikipedia/commons/0/08/Walschaerts_motion.gif

So you have a wheel on a servo. Attached to the wheel is a linkage that connects to a slider running in a track. Turn the wheel and the slider moves back and forth.
Attach the claws to the slider, send a pwm to the servo, and voila.

As for the FPGA stuff: http://www.fpga4fun.com/ is what I currently use to learn Verilog. I played with the rs-232 project and the pong game (which formed the basis for the VGA stuff I showed).

BTW, the $19k FPGA I mentioned today:
http://www.digikey.ca/product-detail/en/EP4S100G5F45I2N/544-2637-ND/2202367

Compared to that, the most expensive Xilinx (also in stock) is almost a steal for $8k:
http://www.digikey.ca/product-detail/en/XC6VHX380T-2FFG1923C/122-1782-ND/2548738

I have no idea how one would verify almost 2000 pins, soldered correctly, properly connected, functioning. How much it would cost to verify a design, making a prototype and finding all those little notes in the data sheet with widespread implications if not addressed properly. What are the thermal and mechanical implications for a PCB having 2k solder points on 45mmx43mm area (1 solder point per
square mm !!!!!)?

Ignoring those technicalities, if anybody has an idea of what to use a chip like those for, I would be interested to hear about it.

Have fun (and let your phantasy go wild)

Hi Markus,

You were looking for something like this:

2.1 Design Purpose

We assume that the purpose of the design is to build an FPGA with the following features:

a CPU similar to the Atmel ATmega8,
a serial port with a fixed baud rate, and
an output for a single digit 7-segment display.

It is assumed that a suitable hardware exists.

Very interesting tutorial indeed.

lol - I was afraid that question would be raised ;).

It actually doesn't matter to me, I start from scratch with both of them. I bought this book from CircuitCellar on how design a microprocessor in Verilog (http://circuitcellar.com/editorsblog/microprocessor-design-using-verilog-hdl/). One of the things that is not covered in as much depth as I would like is .... Verilog.

If anybody can convince me that "the book might be nice but VHDL is the way to go", I will probably switch. I checked, VHDL books are as elusive and expensive as Verilog HDL books, doesn't make a difference from that perspective.

So ... if anyone has any real arguments for one or the other, I would like to hear about it.

Also thank you Markus for a very entertaining FPGA demo and discussion, you have made huge progress since your Larson scanner last month. FPGAs are a topic that is very intriguing and tempting to dive into, although I fear I might not ever make progress on my other projects once I start... :)

Unless you've got a bootloader built in (all of the Arduinos have
builtin bootloaders) then you'll need a programmer of some type.

Solarbotics has a few programmers:
http://www.solarbotics.com/product/52230/ for $32
http://www.solarbotics.com/product/18900/ for $25.
http://www.solarbotics.com/product/50844/ for $16

If you have an older computer with a real parallel port, you can even
make a programmer using just the parallel port connector and some
wires.
