Regular Member Meeting 2008 07 29

Griph: br'ed top section

{{Floating TOC}}
== Time & Location==

July 29, 2008<br />
Members Present: Nick, Ali, Derek, Katie, Timball, Pete<br />
Others Present: Guests: Sam, Cassia<br />
Quorum: Not Achieved<br />
7:38pm - 8:10pm<br />
HacDC, 1525 Newton St NW, Washington, DC. (Space)<br />
Presiding: Nick Farr<br />

== Draft minutes of the last meeting ==

* No quorum was achieved, so prior meeting minutes could not be received.

== The Consent Agenda ==

* No consent agenda this week.

== Minister Reports ==

=== Coordinator in Chief ===

* No coordinator in chief present.

=== Minister of Finance ===

- Would like to start using the cash register for soda and component sales, so people are trained to use it when we go to cons.

- ToorCon is coming up at the end of September, and HacDC would be a good place for a Hackersmart.

- Peter asked if we should assess the cons for the next year, and try to schedule for the next year.

- Nick mentioned the CCC in Germany in December, and other cons\

- Ben noted the wiki has a list for cons upcoming

- Peter suggested we start using the wiki page more frequently, and plan ahead.

- Ben points out there are lots of different kinds of cons, including Otakon (Baltimore), Freaknic (Nashville)

=== Minister of Information ===

- Still looking for input to the design of the website.

- Katie suggested sending a link out to the proposed designed to the list.

- Peter suggested making the calendar bigger and using the standard Google calendar widget, but there were arguments about members stuck in the 1990s who don't use JavaScript.

=== Keeper of the MIBS ===

* No Keeper of the MIBS present.

== Member Reports ==

=== Ben Stanfield ===

Talked with a woman from Safari Online Book program. $347 per year per person to join Safari Online Books. Unlikely to go for this. Ben did ask about discounts for nonprofits, but they have nothing of the kind. This is also not their complete plan, only their "Essential Tech", which means no videos, rough cuts, or extras.

Cassia points out that you can sign up with Montgomery County Library (even if you don't live in Maryland) and get access to Safari Online for free.

=== Pete ===

Peter wants to discuss the physical space uses and if we're planning ahead for getting a larger space?

Nick reported that there are things ongoing. Nick is looking for more space nearby. He'd like to encourage everyone to look for alternative spaces. Requirements for spaces are in the district, near public transit.

Derek had some speculation about having a space in Maryland so there's an option closer to people there, but no immediate action is planned. Someone suggested carpooling.

== Old Business ==

* There was no old business to discuss.

== New Business ==

* There was no new business to discuss.

HacDC Museum

2008-07-23T23:59:15Z

Griph: recreating, with original identity intentionally lost

This project is scheduled for consideration at the June 17, 2008 member meeting.

Ben Stanfield is proposing this project. As this project requires specific earmarking of present HacDC resources subject to the discretion of its participants, it requires membership approval.

== Proposal ==

With the recent -redacted for privacy review- donation, it's obvious that HacDC is now the recipient of some unusual, historical, and unique items. To honor Mr. -redacted-'s memory and preserve the unique nature of his gift, I propose to create The HacDC Museum of Technology, and within the museum the -redacted- Collection of Telephony, curated by HacDC membership.

Because of space concerns, I envision a locked storage box to collect artifacts suitable for the museum that are off-limit for use in projects, but available for examination and research by the membership. Because a storage box is not precisely the ideal for a burgeoning museum, items will be photographed, videod, catalogued, and available to the general public via a website or wiki.

As an organization, HacDC has designated several areas of concentration. The museum will fulfill several of the specific purposes of the [[Bylaws]], including:

* Collaborate on all forms of technology, culture and craft in new and interesting ways.
* Apply the results of its work to specific cultural, charitable and scientific causes.
* Freely share its research and discoveries, using what is learned to teach others.

Initial items for the collection include:

* Scientology eMeter (perhaps the one Scientology submitted to obtain the patent)
* Lineman's handsets
* Blue Box
* AT&T Reference Manuals
* Historical Books
* Korean War Era Military Field Phone (working condition, sound great over 1000' of wire)
* Slide Rules

AVR Lesson: Setup

2008-06-08T21:48:34Z

Griph:

The first step is to get set up with all the necessary hardware and software to start making your controllers do your bidding.

== Programmer ==

A programmer needn't be super-fancy. In fact, you can get by with five wires soldered to a parallel port plug if you'd like. [http://www.instructables.com/id/Ghetto-Programming%3a-Getting-started-with-AVR-micro/ This Instructable] steps through making a parallel port programmer. I'll probably make up a cable or two and bring it in to the space if you'd just like to try it out. Note that if you've got a breadboard, you can skip the step of making a programming cradle and just plug the wires into the correct pins on the AVR.

If you're getting a little more serious, spend $22 and get a [http://www.ladyada.net/make/usbtinyisp/ USB-based programmer from ladyada] or make your own [http://www.xs4all.nl/~dicks/avr/usbtiny/ usbtiny SPI programmer] for maybe $10-15ish. If you're making your own, you'll need to flash an AVR with the supplied firmware, but you can do that with a parallel port programmer or just ask one of us to hook you up.

This part may seem daunting -- it's not. Dive in or get someone to help you. The Ladyada kit is a good first/second soldering project.

== Software ==

The standard toolchain consists of a GCC-based C cross-compiler, the AVR-libc libraries, and the software to run your programmer: ''avrdude.'' Feel free to write the C or assembler code using whatever editor you like best.

For Windows, it's all put together nicely with [http://sourceforge.net/projects/winavr WinAVR]. Download and install. If you're using a parallel port programmer, you'll need to also run the included ''giveio.bat'' file to get yourself permissions.

For Linux, it's not that hard either. I'm most familiar with Ubuntu these days. As of 2008/04, "sudo apt-get install avrdude avr-libc binutils-avr gcc-avr" will set you up. Or fetch tarballs and compile it yourself. (I'll incluce versions here in a few.)

For Mac, I don't have a Mac. Is any of this [http://www.ladyada.net/learn/avr/setup-mac.html from Ladyada's site] useful?

In addition to the compiler and programming software, it's nice to have an [[AVR Makefile]] that automates the cross-compilation build process. Comment in/out the first few defines to match your environment.

== Chips ==

So you're set to program, but you need a couple chips. [http://www.avrfreaks.net/index.php?module=Freaks%20Devices&func=viewDev This page at AVRFreaks] has some of the specs and all the datasheets in one place, but it's a bit overwhelming.

A shortlist of the coolest chips includes:

'''Tiny13''' -- Smallest and cheapest. 8 pins, 5 of them useful. 1k program memory. Goes everywhere. Cheaper and more versatile than a 555 IC. Some hardware SPI/I2C support, but it's a pain to write for.

'''Tiny45''' -- Another 8-pin, but with a high-speed PWM clock and 4k of program memory. ~$0.75 from Digikey. Can be made to run at 16MHz+ using its internal oscillator, making firmware USB a reality. Some hardware SPI/I2C support like the Tiny13.

'''Tiny2313''' -- 20 pins. It's the cheapest/smallest unit with > 5 usable pins. Hardware USART makes serial communication (e.g. with your computer) reasonably simple, which can be sweet for debugging or datalogging.

'''Mega 48''' -- 28 pins. All of the bells and whistles, with 4k program memory. 6 ADC channels, buncha timers, SPI/I2C/USART communications. They'll do what you want.

'''Mega 88, 168''' and beyond -- You're writing micro-controller code that requires 16k?!?! Time to learn assembler, parallel out your tasks to a couple chips, or step up to something like an ARM platform, IMO.

Maybe we could do a few group purchases to get up to Digikey's price-break minimums. Interested? E-mail Elliot.

And while you're at the AVRFreaks page, download both the long and short datasheets for whichever chips you end up buying. The short one has a nice pinout diagram on page two, while the long one explains everything you'll ever need to know.

== Misc. Extras ==

You're at least going to need some LED's to go blink. Pushbuttons are nice for playing around with inputs. Photocells give your creations sight. Motors and motor drivers give you legs. I'm sure there's more than enough scrounge around the space to get everyone started.

[http://www.instructables.com/id/Ghetto-Development-Environment This Instructable] details my current setup, and is a good start.

AVR Tutorial

Griph:

There's a lot of good information out there about programming micro-controllers, but I couldn't find a good, stepwise, lesson-based tutorial. Since a bunch of the HacDC folks are just learning their way around, I thought it'd be fun to put together a mini-course based on the Atmel AVR platform and GNU-GCC. The idea is to have each lesson doable in an hour or so

What follows is a mix of how-to and code snippets and peoples' experience walking through it all. If you're following along and want to contribute, feel free.

== The Basics (take these in order): ==

[[AVR Lesson: Setup]]: Get a programmer, a chip, the software, and some parts

[[AVR Lesson: Output Pins I]]: Basic output and LED Blinky example

[[AVR Lesson: Output Pins II]]: Binary math and Cylon Eyes

[[AVR Lesson: Input Pins]]: Debouncing and Button-triggered Cylon Eyes

[[AVR Lesson: Timers]]: Clocks and how to use them.

[[AVR Lesson: Interrupts]]:

[[AVR Lesson: Pulse-width Modulation]]: An easy way to get analog outputs. Dimming LEDs or Crossfading Cylon Eyes

[[AVR Lesson: Analog-digital Conversion]]: Automatical Dimming Night Light

AVR Lesson: Output Pins I

2008-06-08T21:30:01Z

Griph:

Part of the [[AVR Tutorial]]

== Goals ==

In this lesson, you'll program the micro-controller version of "hello world", letting you fire up your programmer, compiler, chip, LED, and test them all out. You'll learn how to setup and use pins for output, and along the way get some exposure to AVR-specific coding practice.

== The Circuit ==

Possibly the simplest circuit you can imagine: plug an LED into pins PB4 and ground. PB4 is going to go the positive leg of the LED to source current across the LED and light it up.

If you want, you can include a current-limiting resistor inline with the LED (around 100 ohms is good). I've done it both ways -- the AVR will drive the LED at ~50mA, which will burn out the LED over the long run, but for this demo, it'll be fine.

== The Code ==
<pre><nowiki>

/* Blinker Demo */

#include <avr/io.h> /* Defines pins, ports, etc */
#define F_CPU 1000000UL /* Sets up the chip speed for delay.h -- 1MHz for Tiny13*/
#include <util/delay.h> /* Functions to waste time */

#define LED PB4 /* Defines pin PB4 for the LED. I
often incorporate a bunch of the circuit
info in the defines, which makes
porting the code to another chip
easier and reminds you of how to
hook it up. */

int main(void){

DDRB = _BV(LED); /* Data Direction Register B:
writing a one to the bit
enables output. More on the
_BV() macro in the next
lesson.*/

while(1){ /* the main loop, from which we never return */

PORTB = _BV(LED); /* Turn on the LED bit/pin in PORTB */
_delay_ms(400); /* wait */

PORTB &= ~_BV(LED); /* Turn off the LED bit/pin in PORTB */
_delay_ms(400); /* wait */

}

return(0); /* never reached */
}
</nowiki></pre>

== Discussion ==

Even though this is a very short program, it provides a sketch of what most AVR code looks like.

At the top is a bunch of includes, defines, and etc. ''io.h'' defines all of the port and pin macros and is linked to the individual chip's io header during compilation, which allows the same code to work for different AVR chips. You pretty much always want to include ''io.h.'' The delay functions in ''delay.h'' are fairly generic, but depend on knowing the chip's CPU clock speed to get the timing right. Also note that the maximum delay you can request also depends on the chip's clock speed. Read up in ''delay.h'' for details if you're interested. Practically speaking, if you're asking it to delay for 600ms and it's only delaying for 200ms, try calling the _delay_ms() function three times, each for 200ms.

After the defines and includes we get down to the main() function. Most AVR main()'s have at least an initialization section and an infinitely-repeating loop where the bulk of the chip's work gets done.

In this example, the initialization section just sets up the LED pin for output by writing a 1 to the relevant bit in the Data Direction Register for port B. When the chip is reset or powered on, all of the input/output ports are initialized as inputs (DDRB = 0). We write a one to the DDR do set it as output. More on the bitwise math in the next lesson.

The main loop of the function then blinks the LED by alternately driving the output pin high (the supply voltage, VCC) or low (GND, 0v), and it does this forever, or until the chip is reset or powered off. (The return(0) line is just there to stop the compiler from warning about main() functions that don't return -- a requirement of GCC that isn't really relevant to the AVR, but it doesn't hurt the code either.)

== Trouble? ==

Programmer woes:

Is the LED in the correct polarity? (Positive to pin PB4, negative to GND).

Is avrdude complaining? Try unplugging and re-plugging your programmer if it's a USB one. Sometimes it can get out of sync.

If avrdude's not working, you may also be having permissions problems. Solutions include running giveio.bat for Windows or calling avrdude (or the make command) with ''sudo'' for Linux if you didn't set up user permissions for USB.

When the chip is reset or powered on, all of the input/output ports are initialized as inputs (DDRB = 0). We write a one to the DDR do set it as output. More on the bitwise math in the next lesson.

The main loop of the function then blinks the LED by alternately driving the output pin high (the supply voltage, VCC) or low (GND, 0v), and it does this forever, or until the chip is reset or powered off. (The return(0) line is just there to stop the compiler from warning about main() functions that don't return -- a requirement of GCC that isn't really relevant to the AVR, but it doesn't hurt the code either.)

== Trouble? ==

Programmer woes:

Is the LED in the correct polarity? (Positive to pin PB4, negative to GND).

Is avrdude complaining? Try unplugging and re-plugging your programmer if it's a USB one. Sometimes it can get out of sync.

If avrdude's not working, you may also be having permissions problems. Solutions include running giveio.bat for Windows or calling avrdude (or the make command) with ''sudo'' for Linux if you didn't set up user permissions for USB.
