  1. Yup, I specifically checked out 14. Keeping up to date was the first check As far as libusb is concerned: jackal:tcl pkiela$ brew info libusb libusb: stable 1.0.9, HEAD http://www.libusb.org/ /usr/local/Cellar/libusb/1.0.9 (11 files, 416K) * https://github.com/mxcl/homebrew/commits/master/Library/Formula/libusb.rb ==> Options --universal Build a universal binary This isn't a huge problem since running it twice in a row literally seems to work every time, I just didn't know if this was a known issue or not. I can certainly report it as a bug if that would be preferable.
  2. Hi guys, I just compiled OpenOCD on my Mac (10.7 using Homebrew libs because I compiled in support for ft2232 devices as well). Whenever I launch openocd it seems to die the first time around, however if I launch it immediately following it seems to kick in. I ran a --debug 3 on it and here is what it reports when it dies: http://pastebin.com/ahr208hm The funny thing is that this appears to be repeatable. If I kill openocd I can then launch it again and it will fail, at which point I can launch it AGAIN and it will kick in. Board is just the standard Stellaris launchpad.
  3. Too true. Here I was badmouthing TI and I just got the shipping notification at 12:35am on 12/18. Well, better a day late than never Looking forward to tooling around on the Launchpad with you guys!
  4. Welp, Dec 17 come, Dec 17 go, still no ship notification. Unless they're planning on shipping it out literally at COB on the west coast. This is getting just a little ridiculous.
  5. Very nice. Something I'm going to have to try. What's the USB board you have made up?
  6. Haha, well I could have used a Stellaris M3 class chip which are in good availability, but to be 100% honest the lack of a Stellaris prototype board (still on order, exp. ship December) led me to pick up the NXP chips since I could buy an LPCXpresso 1768 board which will be delivered on Monday. As much as I crow about vendor independence, while I'm starting out I'd prefer to keep both my prototype board AND my project board on the same chip. So in this case, yeah I think TI sort of lost my "business" by delaying the Stellaris LP so long. But it's not a big deal. I'll go back to investigati
  7. Decided to go with an NXP 1768 chip, simply due to availability. I'll post updates in the NXP section once I have some, though I think it'll be pretty much applicable to any Cortex processor.
  8. Just ordered an LPCXpresso 1768 and two bare 1768 chips from Newark. Should be here on Tuesday. Excited about getting them up and running! NXP provides a lot of great examples with the LPCXpresso IDE (or maybe downloadable separately, I'm not sure). I2C, UART, etc. are all covered.
  9. This would be awesome to pick up, but the only place I can find it wants $20 to ship to Canada. No way am I paying $20 for a $2 chip
  10. Great point. I'm perfectly okay going with an M3 however, so I'll probably go down that route
  11. Hi everyone! I'm waiting for my Stellaris boards to ship, and they won't be here until December at the earliest, so I thought maybe while I'm reading about ARM development I'd also try my hand at something a little more low level. I'm fairly comfortable with AVR development and one of the things I love about it is that you can pop a chip on a bare breadboard, add a power brick, voltage regulator, a few caps, and you've got a running "board" that you put together with your bare hands. Not that there's anything wrong with prefabbed boards like the Ardiuno or Stellaris, but there's a cer
  12. The problem with ARM development is that if you're looking for a huge support community similar to that of the Arduino, for example, then you'll be hardpressed to find it. It's nowhere near as prevalent in the hobby community as AVR/Arduino or PIC programming, but I'm happy to see that's slowly changing I don't have a good example of servo control, but Texas Instruments has a very good library of tutorials and labs that you can access here: http://processors.wiki.ti.com/index.php/Getting_Started_with_the_Stellaris_EK-LM4F120XL_LaunchPad_Workshop?DCMP=Stellaris&HQS=StellarisLaunchP
  13. Since I'm relatively new at ARM development I'm trying to be as hardware agnostic as possible to give myself plenty of options without locking myself into a specific vendor just yet. I really love StellarisWare, but at the same time I'm starting to think that I might head down the CMSIS direction myself. Heck, my TI isn't stated to arrive until late December and I can start to learn on my STM32F3 board right now. It's a shame because, again, StellarisWare is brilliant for a beginner, but I'm a little worried about my options.
  14. Yeah, for pete's sake, Newark just updated expecting further delivery on TI LP boards Dec 17. I wish I hadn't missed out on the first wave of orders because now I'll be waiting another month to get my units.
  15. I don't have my Stellaris in hand yet, but I've got high hopes for the instructions listed here for a nice Toolchain-IDE-OpenOCD combo: http://www.stf12.org/developers/ODeV.html I'm going to be trying to get this running with my stm32 board so it'll be ready when my TI gets here
  16. Very cool! I compiled a toolchain in preparation for my LP arriving but I might just go with whatever the majority recommend to make it easiest on myself. Did you get OpenOCD and Eclipse running as well?
  17. My monthly project is refreshing Newark.ca to see if they have the LP in stock
  18. I've been following this since my ideal dev environment is my Mac. Seems like the programming app compiles and runs just fine on OSX, and gdb should be up and running with OpenOCD soon too. Hopefully by the time my Stellaris LP arrives there will be a good writeup for Eclipse + Toolchain on OSX
  19. Nope, not yet. Earliest opportunity is 11/19 from Newark which, thankfully, offers next day delivery. I'm actually okay with this. It gives me a lot of time to research the toolchain, SDK, and it sounds like OpenOCD is gaining Stellaris support quickly so maybe that'll be ready to go on OSX when my boards arrive Thanks!
  20. Hi everyone. I'm completely new to embedded development on any scale. I somehow decided to skip the Arduino step altogether because I wanted to get a little closer to the hardware. That said, I have absolutely zero embedded experience so this is a pretty steep learning curve for me. I'm working my way through Programming Embedded Systems from the O'Reilly library, knowing that it won't be 100% applicable, but it's still a great read. I'm hoping to get to the point where I can integrate ethernet capability into my projects since most of my daily life is spent working on Cisco equipment
  21. Oh yeah, no doubt I ordered late and people have it worse than me, however a 2 month turnaround is still kind of depressing Newark is expecting stock 11/19 so I'll probably pick up 2 or 3 once they're in.
  22. TI's delivery date is Dec 17, and Newark is out of stock until 11/19 so I guess I miss out here Though I have two ordered from each, and getting them in will be more than reward in itself
