Collin The AVR Dragon is supported in all modes (ISP, JTAG, HVSP, PP, debug- Wire). When used in JTAG and debugWire mode, the AVR Dragon behaves sim- ilar to a JTAG ICE mkII, so all device-specific comments for that device will apply as well. When used in ISP mode, the AVR Dragon behaves simi- lar to an AVRISP mkII (or JTAG ICE mkII in ISP mode), so all device-spe- cific comments will apply there. In particular, the Dragon starts out with a rather fast ISP clock frequency, so the -B bitclock option might be required to achieve a stable ISP communication. -B bitclock Specify the bit clock period for the JTAG interface or the ISP clock (JTAG ICE only). The value is a floating-point number in microseconds. The default value of the JTAG ICE results in about 1 microsecond bit clock period, suitable for target MCUs running at 4 MHz clock and above. Unlike certain parameters in the STK500, the JTAG ICE resets all its parameters to default values when the programming soft- ware signs off from the ICE, so for MCUs running at lower clock speeds, this parameter must be specified on the com- mand-line.

My understanding (someone correct me if I'm wrong) is that the ISP clock frequency should be no more that 1/4th of the clock frequency of the MCU you are trying to program (as indicated in the man segments that Collin snipped). In fact, the Arduino folks recommend a frequency of 125 kHz for programming a "virgin" 168 (which runs at a clock of 1MHz). That would correspond to -B 8. On the other hand, I've had pretty good luck running at -B 1 for 16MHz 168 programming. But I don't think it hurts anything to program at a slower clock speed, it just takes longer. Perhaps things have stopped working for you because you are running your MCU clock at a slow enough speed that things aren't reliable with the default -B value? Are your clock fuses set consistently on all the chips you are trying to program? BTW, since you have a dragon, if you ever need to use the high voltage programming mode to rescue a chip with bad fuse settings, Atmel *strongly* recommends that you do the programming on board the dragon and not in a target system. That is because there are no level shifters to protect the high voltage programming lines (but there are on the ISP lines). To do on-board programming you need to populate the prototype area on the dragon. Buried in the Atmel documentation is a suggestion of how to do this with some headers and a ZIF socket. I've done it if you ever need a pointer to how to set it up. -scott On Jul 31, 2009, at 10:35 PM, Jared Boone wrote: > I second Collin's remark.

I programmed over hundred devices out of the tube with a bit clock setting of -B 1. No problems. Then parts from the same batch wouldn't program. I changed the bit clock to -B 100 and the parts would program. After the first programming the devices will program with -B 1. If have noticed this on 168, 328 and 644's. I am thinking the initial clock fuse setting of some devices may be set differently. Maybe changing a clock setting first and then flashing the bootloader (or application). Since I haven't needed to program a lot of devices I haven't checked this.

Are your clock fuses set consistently on all the chips you are trying to program? BTW, since you have a dragon, if you ever need to use the high voltage programming mode to rescue a chip with bad fuse settings, Atmel *strongly* recommends that you do the programming on board the dragon and not in a target system. That is because there are no level shifters to protect the high voltage programming lines (but there are on the ISP lines). To do on-board programming you need to populate the prototype area on the dragon. Buried in the Atmel documentation is a suggestion of how to do this with some headers and a ZIF socket.

Collin The AVR Dragon is supported in all modes (ISP, JTAG, HVSP, PP, debug- Wire). When used in JTAG and debugWire mode, the AVR Dragon behaves sim- ilar to a JTAG ICE mkII, so all device-specific comments for that device will apply as well. When used in ISP mode, the AVR Dragon behaves simi- lar to an AVRISP mkII (or JTAG ICE mkII in ISP mode), so all device-spe- cific comments will apply there. In particular, the Dragon starts out with a rather fast ISP clock frequency, so the -B bitclock option might be required to achieve a stable ISP communication. -B bitclock Specify the bit clock period for the JTAG interface or the ISP clock (JTAG ICE only). The value is a floating-point number in microseconds. The default value of the JTAG ICE results in about 1 microsecond bit clock period, suitable for target MCUs running at 4 MHz clock and above. Unlike certain parameters in the STK500, the JTAG ICE resets all its parameters to default values when the programming soft- ware signs off from the ICE, so for MCUs running at lower clock speeds, this parameter must be specified on the com- mand-line.

One thing I have run across in my information surfing which might be of interest is the Funnel IO board (http://www.sparkfun.com/commerce/product_info.php?products_id=8957 ) which is basically a small board compatible with the LilyPad version of the Arduino. The thing which makes it relevant to this thread is that it comes with a built-in socket for an XBee, so you don't have the additional expense of an XBee adapter board or shield. It also comes with circuitry for supporting Li Polymer battery and the basic intent of the Funnel IO board is to support wireless (and possibly battery powered) data collection in a fairly cheap and small package. The Sparkfun page has pointers to further information about Funnel IO. -scott On Aug 5, 2009, at 11:03 AM, Ben Bleything wrote: > On Wed, Aug 5, 2009 at 10:51 AM, dan p > wrote: >> Anyone have opinions about xbee?

I suspect we could pull this off with a little bit of thought. We can chat with Ward about it at the event and figure out how reasonable it would be to reconfigure the space for a bit. -------------- next part -------------- An HTML attachment was scrubbed...

I'd be into trading for an arduino/teensy/AVR/whatever thing, parts that I could use, audio jacks, nice pots, cool old knobs, or really anything interesting. -j On Aug 9, 2009, at 2:48 PM, Thomas Lockney wrote: > Sadly I have yet to get a single bite on my previous email asking > for volunteers to help shuttle people up to the event tonight. > Basically, for those of you who don't know the situation, the doors > and the elevator up to AboutUs are locked on the weekends.

Not particularly, if the price isn't significantly different. These are for an art project by some acquaintances of mine, and their grant wasn't as large as they'd hoped. (I could probably fit the code into one of the ATmega8s that Surplus Gizmos has for a couple of bucks, but I didn't want to risk their project not meeting their deadlines.) It's an interesting application, btw. I'll ask them if I can bring the prototype down to a Dorkbot meeting. (I don't know what the etiquette among artists for this kind of thing is, or I'd tell you more about it.) Regards, d.

I don't know what Jason was talking about specifically, but in my mind the security issue is more that it's an unencrypted and unauthenticated protocol, meaning that I can bring my remotes to your house and turn your lights on and off.

That's exactly the point. The wireless control of your equipment can be done trivially by anybody with the same cheap gear. This might not seem like a big deal until, say, somebody decides to repeatedly flash your lights on and off for hours at a time....or better yet, they turn off all your house lights at the very instant that you take the first step into the basement.

Totally crackable still but it's not like it's controlling your front door or your alarm system. (Is it??) I liken it to using an older model cordless phone. Sure, someone can listen into your conversations but who would want to. I guess it's a case where the technology can be used where it's appropriate. I.E. Don't wire up Grandma's life support system or the beer fridge to it. Also, the reason it doesn't work from one side of the room to the other is typically because both the transmitter and receiver are on different legs of your house wiring. For typical 120V houses, the power company delivers power to the building on two 120V lines that are 180 degrees out of phase. When you combine the two together, you get 240V to run your stove, dryer, water heater, A.C. unit, etc... For the rest of the appliances you break off one "leg" and wire it to your lights and outlets. Electrical panels are designed to equalize the load for 120V devices between the two legs. So, basically, unless you know how your panel is designed and which breakers control which outlets or lights in your house, it's a guess as to whether or not the x10 stuff is going to work. However, they make bridges that transmit signals between the two legs: http://www.smarthome.com/4815/X10-Signal-Bridge-Leviton-6299/p.aspx - Greg -----Original Message----- From: dorkbotpdx-blabber-bounces at dorkbot.org [mailto:dorkbotpdx-blabber-bounces at dorkbot.org] On Behalf Of Jason Plumb Sent: Thursday, August 13, 2009 2:35 PM To: A discussion list for dorkbot-pdx (portland, or) Subject: Re: [dorkbotpdx-blabber] x10? insteon?

I could probably help you out, I'm not exactly sure what sort of audio analysis we can really do on a microcontroller, but.. if you don't need much analysis, if it is just levels, or very basic stuff..

Hmm, Wireless MIDI? does such a thing exist? or maybe you want something that has a MIDI input that then wirelessly communicates data to all the rest of the devices?

I would love to be reunited with it soon. - Lena From armatronix at sbcglobal.net Tue Aug 18 01:34:03 2009 From: armatronix at sbcglobal.net (Hans Lindauer) Date: Mon, 17 Aug 2009 22:34:03 -0700 Subject: [dorkbotpdx-blabber] New light project collaborator(s) wanted In-Reply-To: <20090818023945.GI23963@silverninja.net> References: <4A8A02D2.1050502@sbcglobal.net> <20090818023945.GI23963@silverninja.net> Message-ID: <4A8A3D4B.3080707@sbcglobal.net> Alex Norman wrote: > On 0, Hans Lindauer wrote: > >> Hi all, >> >> I've committed to another LED project for a local band, and I wouldn't >> mind if others wanted to get in on the action -- especially programmers. >> >> > > What's the band? > I'm not supposed to say, although I can tell you if you help out. > >> --- >> The first part of the project involves a 1-dimensional string of 24 >> ShiftBrite full-color LED modules: >> http://www.macetech.com/blog/node/54.

Do you have another servo to try? I've driven servo's dozens and dozens of times with various types of logic and never had that problem. I'd have to admit I've only driven one with an AVR a couple of times but I never had any voltage drops like that. I'm basing my experience on futaba 328 class servos. I've never dealt with the digital servos but I hear they are much easier to control from a microcontroller. I can't imagine they would draw more current but maybe? What size / type / brand of servo are you using? What pin from the 328 are you using to drive it? Oh hey, what are you using to measure the voltage? Could your measurement method be doing a RMS of the voltage or fouling the results in some way? Also: "(The servo power is 6V, and I run the AVR with a diodes from 6V to Vdd(AVR), and GND(AVR) to 0V, so the microcontroller's 5V is more-or-less centered within the servo supply.)" So are you relying on the .7V drop across the diode (what kind of diode?) on both power rails to give you a "center-tapped" voltage source for your AVR (4.6V)? If so, why? Most R/C servos will operate on 5V. Then HOW are you measuring your voltage drop? Where is your scope probe / VOM / Magic-Measuring-Device grounded to? Also, what does that do to your VCC->Gnd measurement of your AVR when you draw more current through the diode? Aren't you creating an odd potential between the two grounds of the system? It seems to me that your "0" presented as an input to the servo (coming from the AVR) would really be a .7V to the servo which is dangerously close to the .8V "undefined state" for TTL which would cause the input circuit to oscillate wildly and therefore just SUCK current like mad. I imagine it would get squirrely potentially causing all sorts of bad things. What about trying it with a 5V supply to power the whole thing and losing the diodes? Or just using a diode on the VCC rail? As to your question as to what the input looks like... On analog servos, I've always assumed it looks like a TTL gate structure (LS type) but that's entirely a wild guess that I really can't back up. -greg -----Original Message----- From: dorkbotpdx-blabber-bounces at dorkbot.org [mailto:dorkbotpdx-blabber-bounces at dorkbot.org] On Behalf Of dave madden Sent: Monday, August 24, 2009 7:18 PM To: dorkbotpdx-blabber at dorkbot.org Subject: [dorkbotpdx-blabber] Servo Control Have any of you Dorks controlled an R/C servo with an AVR?

If so, why? Most R/C servos will operate on 5V. When I breadboarded this circuit, I noticed that the servo would suck down a lot of current when moving, and the CPU voltage would drop (due to my wimpy-ass breadboard power supply). Also, I read that servos are often spec'd at 6V, and work well there. So I figured I'd use a 7806 to drop wall-wart input down to 6V for the servos, and a couple of diodes to drop 6V down to <5 for the logic. I used a diode on both sides of the CPU supply, although I could have put both on the positive side (and, with the 0.7V drop, I don't really need both diodes to knock 6V down to <5.5). The diodes are just standard 1A units. My meter said Vf was ~0.55V, but under load (30-100mA*) they show a drop of ~0.7V. Therefore, according to my DMM, the servos are getting 6.09V, and the AVR is getting 4.65V. An unloaded GPIO output goes from 0-4.5 on the CPU side, or 0.5~5.2 referenced to servo ground. A loaded GPIO goes -0.4~1.0 on the CPU side, or ~0.4~1.8 on the servo side. I also tried shorting out the ground-side diode, so the CPU runs at ~5.3V. More-or-less the same loaded/unloaded GPIO signal levels, just shifted as you'd expect. > As to your question as to what the input looks like...

That's mostly what I'd expect too, but the AVR should have no trouble pulling a TTL input _up_. At least, pulling it up to 2.2 or 2.7V or so. I'm going to try to rig up a sense resistor in the signal line to see how much current is flowing there. And I'll have to re-read the ATmega manual. I've been working on a bunch of different CPUs recently, and I can't remember whether the AVR has outputs switchable between open-drain, open-drain+weak pull-up, and totem-pole (strong pull-up). Maybe I'm configuring the outputs wrong (although the unloaded outputs snap right up to Vcc...) BTW, I stuffed one board with an ATmega168, and it draws ~90mA. One with an ATmega328 draws only 25 or 30mA. I don't know what that's all about. I had trouble with an earlier (different) batch of boards from Advanced Circuits (shorts & etc) so maybe it's the PCB? Or maybe the ATmega328 is just MUCH more efficient than the '168? [Hmmm, I got a clean, scopeable connection to the Airtronics servo, and it doesn't move at all. I guess the 1.8V "high" pulse isn't tall enough to trigger it. Grrr.] d.

I looked up the specs for your servo. I know I have run mine off a ni-mh/ni-cad 4pack (4.8V) as well as powered other circuitry from the same pack. Anyway, the specs http://www.hitecrcd.com/product_file/file/47/HS325HB.pdf show all test voltages at 4.8V so you might try that and see if you're still getting the same problem. Maybe the servo is bad? This would eliminate the diodes as a potential problem. Other than that, I think Don has a point. Bring it to the meeting.

D'oh, my bad! I had two problems going on: first, my code only initialized one of the servo outputs (the one I was testing with on the breadboard). So the other servo outputs were actually configured as inputs, but due to the way the ATmega operates internally (which is not 100% clear to me) if you try to wiggle a pin that's configured as an input, you can still see it toggle externally if it's not loaded very heavily. So when I fixed that, the Airtronics servo started working, but then the Futaba knock-off started oscillating. That's probably because the "low" of the servo pulse was at ~0.6V, due to the diode in the CPU's ground line. I shorted out the low-side diode and now everything works. Yay! I'll bring a couple of controllers, and try to get the artists to bring along a prototype, to the next meeting. Thanks for the help, everyone! d.

When you have an AVR pin configured as input, the PORTB bit is used to enable or disable the internal pull-up resistor. There's a very weak pull-down present at all times that's implicit in the pin's protection circuitry, and so toggling PORTB while in input mode will throw the pin weakly to ground and somewhat less weakly (~25K ohm avg) to high. With no load these aren't distinguishable from a normal low/high.

I totally can't second this loud enough! THANKS JARED! As a community, it takes a LOT of effort by a LOT of people for things to work right, and this is another great example of somebody stepping up, volunteering their services, following through, and KICKING ASS. To you, it might just seem like a few videos tossed up on Vimeo -- but really, think about it -- Jared went WAY out of his way to bring his camera, tripod, and enough empty storage media to store about 2 hrs of HD video, show up early to set things up, nag me to bring an audio recorder, ensure that tape was rolling the entire time (while jumping in to pan/zoom when required), later pull off the video, deinterlace it, synchronize it with the separate audio source, add titles (while keeping track of everybody's names!), downscale, and then upload (complete with URLs)...in addition to a ton of other things I'm sure I'm either trivializing or forgetting. Point one: HUGE THANKS TO JARED (hint: buy him a beer on Monday!) Point two: As a community we must all step up, chip in, help out. I'll use this space to also try and just blanket thank everybody who help make 0x04 a success. From Ward to hosting us, to Amber for instigating, to *all* the great presenters, to the beer sponsors and snack bringers, and all of you who showed up and those I'm sure I'm forgetting....THANKS! -jason http://noisybox.net From curator at ongallery.org Fri Aug 28 15:41:06 2009 From: curator at ongallery.org (Benjamin Foote) Date: Fri, 28 Aug 2009 12:41:06 -0700 Subject: [dorkbotpdx-blabber] Dorkbot show in October at ON Gallery In-Reply-To: <10e900420907101932s76fd66efhddcd8b3372017f23@mail.gmail.com> References: <10e900420907101932s76fd66efhddcd8b3372017f23@mail.gmail.com> Message-ID: <10e900420908281241k6c03a723pd1ae7bc12f679c31@mail.gmail.com> Hi All, Thanks to all of you who have signed up to participate in the October show at ON. I think it's gonna be great. http://dorkbotpdx.org/wiki/on_gallery_show_oct_09 Please consider coming down to the gallery this coming First Thursday for September's opening to enjoy the art and to get a feel for the space.

The idea being able to detect the magnitude of the sound/noise and output a DC level signal that could be read with a cheap ADC on a uP. This is for a very non traditional green application... no cool flashing lights, but it's neat, I promise. Oh., and it needs to be really really low-power. Ideally, we might even be able to use this little break-out board form SparkFun. If anyone has any ideas, let talk... perhaps we could work something out. http://www.sparkfun.com/commerce/product_info.php?products_id=8669 Thanks!
