[quote author="Bruce"]I can't post URLs yet, but if you search Mouser for 0901420006 you get a Molex connector that looks promising to me. It's keyed in a way that looks to match the V4 board photos at seeed, and they have almost 46k in stock so they must be pretty popular. Has this problem already been solved, or if not is there some reason this connector wouldn't work?[/quote] That particular connector only has 6 positions (2 rows of 3). But even if you select the 2x6 version, that family of connectors uses crimp on terminals which are a pain to use and are best done with reasonably expensive crimping tools. It is hard to say whether or not it would actually fit into the shrouded header that Seeed is using. The correct, and seemingly very hard to find, connector is an IDC.
[quote author="MickM"]Hi; sdixon - yes I actually just bought a Dragon. Then I found all the horror stories of how easily they die. So, until I get my "Lair" built I have not even plugged it in yet. Mick M[/quote] Yes, it is possible to slay a Dragon. I've had it happen. But you can generally protect it by either building a Lair as you mentioned or by always plugging it into a powered USB hub. And if you do kill it, you can repair it. I've done this successfully. The reference is http://www.aplomb.nl/TechStuff/Dragon/Dragon.html. Note that there are two version of the repair instructions on that page and you want the one for the newer version of the Dragon (with mounting holes) which is near the bottom of the long page.
It is also worth mentioning the Atmel Dragon programmer. It is about $50 as I recall and it can program a wide selection of Atmel processors including XMegas. It also will do high voltage serial and parallel programming to rescue fuse settings. And, very important, it is by far the cheapest way I know of to be able to do DebugWire in circuit debugging. It's worth thinking about unless you are mainly doing a fuse doctor project as a learning experience.
I haven't actually used it yet but this project seems to have a nice explanation of PID controllers and a good Arduino library. Notably, it includes autotuning for the PID parameters.
[quote author="bearmos"]That's where my confusion/disbelief comes in - I can literally pick up a quart (~1 liter) of IPA (97% pure) from the same place I buy tomatoes. . . for about somewhere around $1. Then again, Ethanol (aka everclear) requires you be >21 years old to purchase (and, like all licquer in my local) is regulated by the state. I guess it's just a difference in what governments view as being dangerous.[/quote]
In the US, there are a couple of commonly available forms of IPA. The most common and cheapest, used for cleaning mainly, is 70% IPA (I believe the rest is water). There is also a 91% version which is listed as used as an antiseptic. Technical grade IPA (99.9%) is much more expensive and is available at, for example, electronics supply stores. I try to get the 99.9% IPA to use to clean electronics since I don't really want to introduce a bunch of water while cleaning. It runs around $10 for a quart, roughly.
[quote author="arhi"]NXP have 9bit hw spi ?[/quote] Yeah. I used the lpc1343 to run a Nokia LCD which has the usual 9 bit SPI interface. You can set the SPI hardware to run at anything between 4 and 16 bits. Pretty handy.
The 9 bit SPI issue is one reason I moved from STM Cortex M3 to the NXP M3 instead. Those have selectable 8 through 16 bit SPI interfaces so you can drive all those 9 bit display directly with hardware.
I guess I read the OP request a little differently. Not so much what the file format would be but what the data model for a parts object would be. That is, what are the fields and what do they mean so that the different web sites and programs can try to exchange information effectively. I don't really have an idea about this to contribute unfortunately, but I can certainly see it is a problem whenever I contemplate an electronic inventory of my parts collections. Just trying to collect together the information from the various suppliers is not easy at this point.
Oh, and one thing about CSV format. Unless there is something about the CSV standard that I don't know (certainly possible) it seems to me that the biggest downside of CSV, compared to XML or JSON, is that CSV is basically a model of a 2D table, without any clean way to represent hierarchical data. If your data fits nicely into flat rows, then great. Otherwise, you need a more structured format, it seems to me.
If you check page 19 of this Pace manual (http://www.desab-elektronik.se/prod/pac ... /st20a.pdf) you will find a troubleshooting guide which gives some resistance and troubleshooting information which should help sort out which pins are which for the older sensatemp heaters. I haven't seen the intellisense models and don't know what the differences are.
Excellent! I'm glad you got it going. CrossWorks is a nice package on OS X. I just can't justify $150 for personal use just for the ARM version. I'd love to see someone get OpenOCD working with SWD on OS X. I haven't looked at the current progress of SWD in OpenOCD. Last time I looked, a few months ago, it still wasn't there yet. [quote author="pppd"] I will also try to make a combined jtagkey/ktlink SVF for the CPLD so I don't need to flash it every time I change my project.[/quote] That would be really handy. Hope you get it working.
I hooked up my LPC1343 board via SWD lines to the BBV2 (KTLink) and fired up my license expired version of CrossWorks. If I try to connect to the target it doesn't find one. However, if I first open an LPC1343 project that I was working on before, then connect to the BusBlaster it finds the Cortex M3 target just fine. And I can do a few other things without a license including attaching the debugger and doing a little poking around. So I suspect you are having a problem because you don't have an appropriate project open before trying to connect to your target. At least, that would be consistent with the behavior I'm seeing.
[quote author="Tarloth"]Sorry, I didn´t know one. One friend of mine program from scratch a couple models of that boards and work OK without problems (with the original soft the same board fail a lot) but do this job for your work and it´s confidential. Maybe I can ask him if he can donate the sources but he """hates""" the open something and I see hard to convince. For sure he can oriented us, but, I ask him in the next days and use OLS as temptation. Sorry for not can help better.
In case of he can/like help, have you a dongle to copy the ucontroller code part?[/quote] Thanks for the information. If you find out anything more it would be great. As far as a dongle, I'm not sure. I've got a fair number of programming dongles but it depends on what these boards need. Since I haven't looked into what it takes to reflash the firmware I really don't know.
[quote author="arhi"] maybe we can storm some Australian online seller to send us those tips :D ...[/quote] It would be nice to find some place which sold them via mail. Of course it might also be possible that Dave Jones just has a Pace iron and that is why he can get the dimpled tips...
