I don't know what happened since I installed gladevcp for testing. I don't remember having any of the package dependency problems you pointed out. There are at least 3 possible reasons for that though (bad memory, already installed packages, or wiki changes). All gladevcp package dependencies actually should be in master, and therefore be installed, which is why I removed them from the wiki. They were needed before all deps were merged into master. The error you pointed out hinted at a missing package resulting from a broken install, which I tried to help you with but which is a bit hard to diagnose without further details. Are you sure you pulled master completely, and properly configured and built? Yes, I followed the instructions on the wiki page, http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2 and also did a git pull, which said up to date - the gtkglext1 were not installed already and seem to be missing from the packages with the distro. That aside, I still would be interested in reports of doing an install from master onto a pristine 10.04 and 8.04. That was a pretty much pristine 10.04.

Re: [Emc-users] FCM8201,2 and IRAMS
For the soldering issue, I am thinking that there are people on the list that already have the skill and tooling, and might be willing to run a batch or two for a nominal fee. Many hands make light work so if (big IF) a batch of boards gets made, there may be an inquiry made for soldering them. All you need is a soldering iron with a small tip. With good eye-sight, or a magnifying lamp, you can solder individual pins of a 0.5mm pitch chip. Or use the flood solder and de-wick method. A few years back (maybe more) I had Sparkfun make some boards for me. The price was very good, but I had to wait a few weeks for them to fill a panel, then send the job to China, have the board house find a space in their normal production schedule, then ship the panel to SF. SF would then break the panel out and ship. It seemed to be the best deal going at the time, but I guess hobby fab has come a long way since then? They forked off another company to do that, www.batchpcb.com. They fill a couple of panels a day now. Still a two week turn around to get the boards built, but it's hard to beat the prices for one or two small boards. -- Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!

On Fri, Jan 21, 2011 at 08:51:40AM -0800, Kirk Wallace wrote: I was trying to use an ATmega because they are 5V chips, but I kept running into a problem of having the different functions I wanted being on the same pins. The Xmegas seem to have less pin function sharing. Plus on-chip hardware quadrature decoders, and on-chip hardware routing of I/O signals to counters, etc. As well as higher cpu speed. They are good chips to master, I think. I am thinking the first batch of boards should have just the parallel port interface, power supplies and other essentials to get the uC to run, then break out the rest of the pins, so peripheral development could continue. The more pins available would allow for more flexibility in how the uC could be used. If a header is used there, then IDC connectors would allow peripheral boards to be easily swapped. I would also like to follow best or better design practices. So I will need those that know better, to provide guidance. To that end, I also tend to copy other designs that are common for an application. The 10 years I spent designing uP-based digital hardware have been followed by 20 years of embedded software hacking, with only the occasional hardware design, but I'll cheerfully throw in suggestions, FWIW. So far, I have only looked at this chip: http://focus.ti.com/lit/ds/symlink/sn74lvc4245a.pdf That's just the ticket for the data path. Another, permanently enabled could serve for control lines in one direction, if it saves enough discrete components. but currently, I see that understanding the EPP software as my next goal. I have an ATmega setup that I can use to get an EPP component sorted out, then I can move this to the Xmega. Sounds good. The code's portable, bar some initialisation and pin names, I expect. (Haven't used an xmega yet.) A few years back (maybe more) I had Sparkfun make some boards for me. The price was very good, but I had to wait a few weeks for them to fill a panel, then send the job to China, have the board house find a space in their normal production schedule, then ship the panel to SF. SF would then break the panel out and ship. It seemed to be the best deal going at the time, but I guess hobby fab has come a long way since then? I just hand-solder SMD boards, keeping to SOIC and TQFP packages with not too many pins. TQFP44 was much quicker to hand solder than old-fashioned DIL, the first time I tried it. Just syringe a stripe of flux along each row of pads, plonk the IC down and align by eye, tack two diagonally opposite corner pins to hold the IC, load the hollow in the special tip with enough solder, then wipe along the row of pins, thus soldering 11 pins in 1.5 seconds. (That wipe speed works for me.) SMD discretes are slightly fiddly, but OK in 805 size, I find. (1206 is easier, but I hate wasting the space.) SOT23 transistors are a bit awkward, so I prefer an array if there are several in the design, and the layout can tolerate it. By the way, I tend to prefer GEDA for schematic and board layout. I had a hell of a time making new components in Eagle, which I find easy in GEDA. On the other hand, GEDA has very few pre-made components so one ends up making a lot more of them. Ah, that's understandable. (I've persisted, and have made a number of new Eagle components, including micros. The only thing which still gives me trouble is allowing connection to either the lead or the tab, where e.g. a transistor's collector or drain is on both.) I noticed the IR2130 on the wiki page. I hadn't seen it before. The PLCC44 package would be easy to lay out, with the 3 high-side output pins beautifully isolated. If you do come to need an Eagle component for that, I'd find it interesting to do. I'd make the pads a little longer than normal, to make it easier to hand solder. (With one wipe of a hollow-tipped iron to do each side.) But whichever package is most available might be best. A component macro for the SOIC 28 would be quicker.) At first glance, I thought the 0.5v threshold of the current comparator would be power wasting in low to medium voltage applications, but then I saw the current amplifier. That saves adding something like an LM833 to allow a sense resistor in the milliohm range. Ah, and it has separate Vss and Vso pins (like the IR2110 and IR21834), allowing separate logic and power grounds. Now an important question. Where is it planned to source the BLDC motors? :-) Erik -- Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!

There is a fair amount of activity with DIY out-runner motors in the model airplane community. Occasionally, they can get enough orders together to have a batch of custom silicon steel laminations made. The bell, magnets, bearings, hub and stator windings are easy enough for an individual to make. There is at least one person on this list that has an out-runner on their mill spindle. Typically these motors don't have rotor sensors, so adding Hall sensors will most likely be needed if one wants to start the motor with a load. I would really like to try to make an out-runner that caters to an axis application. It certainly isn't like we can't do the machined parts. I have a link to a lamination manufacturer in the Los Angeles area that indicates they will do short runs, but I'm not sure a punch die would be too difficult to make. Finding a source of the silicon steel remains a problem. I think an in-runner would be more difficult because fixing the magnets to the rotor and keeping them there at high RPM and temperature might be beyond DIY technology.

[Emc-users] Halscope as an oscilloscope?
I'm currently working on a stand-alone stepper controller based on an Arduino. As I get further into this I'm feeling the need for an oscilloscope so I can actually see if my code is giving me the results I want. Not having one at my disposal I got to thinking that I could use Halscope somehow. Is this possible? Any ideas of how to accomplish it?

Any ideas of how to accomplish it? halscope can make a pretty reasonable logic analyzer, using a parallel port for input. It should work ok for looking at step/dir signals. The biggest limitation is that it can only sample as fast as your base thread, so you're somewhat limited in the speed of signals you can examine. -- Sebastian Kuzminsky -- Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!

Greg Someone may call me out, but I believe halscope doesn't have any inputs from the outside world. I would tend to go shopping for a decent, at least dual trace, 100mhz scope and some decent 10x probes, (check MPJones for decent, reasonably priced probes) mainly because the chopper waveforms present in a modern drive need at least that amount of bandwidth in order to be able to reproduce what is going on, allowing one to study dead times and such. These circuits often have sub 10 nanosecond rise and fall times that means 100 mhz. Or more. I currently have had a Hitachi 1065 for about 15 years now, and its held up well, paid about $1200 for it used way back when. Some computerized measurement modes are available with this one but not the full monty, just what you commonly need. Worth every penny, its bandwidth rolls off above 100 mhz slow enough that I can use it for troubleshooting in a 180mhz circuit as long as I recognized when I have put the amplifiers into a slew rate limited state. For a newbie at using a scope, that may not be so obvious, but I have had a scope probe in one hand for 60 years. Heck, I can't do much more than check a flashlight battery without reaching for the scope probe to really see whats going on. There are whole catalogs of slower scopes whose prices look attractive, but a bandwidth of only 20 mhz will lie like a rug about these circuits because they are so slow. Hitachi, except for the v-1085, which has triggering problems, makes a good, long lasting scope at a great price considering the specs you get for your dollar. Steer clear of older tektronix scopes (2235/545's etc) as their custom made input attenuators go out of calibration in ways the scope probes capacitor adjustments cannot cope with. And they are not repairable as those parts aren't available after 5 years, about the same time it needs fresh ones. -- Cheers, Gene There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Greg Someone may call me out, but I believe halscope doesn't have any inputs from the outside world. Sorry, but I have to While Halscope itself can only read internal signals, anything you want can, in principle, be piped into the Hal environment. What you'd do is set up a base thread at some suitable rate, and run Halscope and the parport module on that thread, with the parport data bus set to input. Then, you could have Halscope bring in those signals for display. Now, whether this is worth all the trouble to set it up is a good question. On the other hand, if at some point somebody wanted to see how some device was performing when commanded by EMC to produce some signals for moving something, then it would be the ideal way to analyze the system. You could see internal EMC signals related to motion, the commands sent to the device, and the step pulses or whatever produced by the device. Now, if you want an analog scope, it gets much harder, but Greg was wanting to see step pulses, so that would be easy with the parallel port. I would tend to go shopping for a decent, at least dual trace, 100mhz scope and some decent 10x probes, (check MPJones for decent, reasonably priced probes) mainly because the chopper waveforms present in a modern drive need at least that amount of bandwidth in order to be able to reproduce what is going on, allowing one to study dead times and such. These circuits often have sub 10 nanosecond rise and fall times that means 100 mhz. Or more. Well, an analog scope can be quite useful when measuring repetitive events. It can also be a HUGE pain when measuring single-shot events, as are really common when debugging motion systems. So, a digital storage scope is a real boon if you are going to do a lot of this work. If all you need is to see digital signals, then maybe using Halscope through the parallel port might be OK, assuming a 50 KHz sampling rate is adequate. Steer clear of older tektronix scopes (2235/545's etc) as their custom made input attenuators go out of calibration in ways the scope probes capacitor adjustments cannot cope with. And they are not repairable as those parts aren't available after 5 years, about the same time it needs fresh ones. Well, Tek had two lines, the economy line and the pro line. Yes, the 22xx series was the economy line, and most now probably have non-repairable problems. The 24xx line were more expensive new, but can be had fairly reasonably, now. I had a BK for years that finally died, and I have replaced it with a Tek 2465. These have one of the best writing rates (means: bright display even on slow rep-rate signals) on any analog scope, ever, without going to microchannel plates, which you DON'T want! But, really, for motion system debugging, I'd MUCH rather have a digital storage scope. You can capture a single-shot event and sit and look at it as long as you like.

You betcha - finding inputs into HAL is truly no problem. That's what it's for! Then, you could have Halscope bring in those signals for display. Now, whether this is worth all the trouble to set it up is a good question. A 13 input 4 output (kind of slow) logic analyzer for about $0 is fairly appealing to someone who doesn't have a logic analyzer and needs one... Running only parport read and halscope_rt in a base thread might make it possible to run it quite fast. It would be interesting to try. We get 50kHz on any old hardware doing math for stepgens - with care (smp with cpu isolated) and just reading could you get 250kHz? 500? That's starting to be very useful territory. But as a general purpose scope, being able to see analogish stuff is the primary mode of operation (for me?) and halscope and a parport really wouldn't be any use at all. -- Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!

Re: [Emc-users] DIY BLDC Motors - FCM8201,2 and IRAMS
Hi guys I think you would do better to leverage of the work done by others on bldc drivers. The open-bldc project is very advanced in getting nice control of the motors using an stm32. h Piotr has already prototype hardware available for a control section (his intent is to create seperate output sections for different motors). He has done all the hard yards of creating toolchains and JTAG programmers built documented etc. He has boards made. Whilst his interest is not cnc he is a big open source fan.
