  1. Don't get me wrong, it's not the fact that they require the applicant to be fluent in English that I find so funny. It's the "must have be" part... or am I missing something, not being a native speaker myself?
  2. Having to purchase the stick is a real nuisance... because 1. I already got one and 2. While the stick is only ~$25, they want >$40 for shipping to Germany. I purchased it and had it sent to my Borderlinx P/O box. Not sure if I will initiate the delivery to Germany or just have them discard it To bad I didn't look here during the presentation. I could just have sent the stick to one of you guys... :/ Cheers TomKraut
  3. F28035 Piccolo ... for now. We just started evaluating and so far, the performance seems to be sufficient.
  4. OMAP3530, mostly, but also AT91. And we just started building a BLDC control solution with TIs C2000 series, which takes me back to more "bare-metal"
  5. The wake-up by RC circuit looks very interesting! But is it really more energy efficient than LPM3? I'm always amazed at how little power the MSP draws in the LPMs, wouldn't charging a cap require more energy? Cheers TomKraut
  6. Hi everyone, after reading the forum for months and posting for a few weeks, I thought I should say 'Hi'. I'm a software developer and work mostly with ARM and Linux, on a OS level. I write drivers and get Linux running on custom build hardware, application development is usually not part of my job. I started my career working with
  7. What on earth has this to do with DSPs? When I got the email I was expecting an ezDSP kit. The Sitara series is ARM only, no DSP core! As a TI deal, this is worthless! If you need a real TI EVM you have a reason for it, and then it doesn't matter if it costs $500 or $1000. If you don't need it, you won't spend $500 ! This is not a Fraunchpad for $14.50 or a Chronos for $50 which you buy impulsively because it's cheap. @bluehash: If you want to get into Sitara development, why not buy a CraneBoard or BeagleBone? Or just a good old BeagleBoard, it's basically the same processor. Chee
  8. I don't think that this has anything to do with *architecture* compatibility. If there is no supplied binary you need to run, it doesn't matter which CPU architecture you use. This seems to have something to do with the external address bus used on the listed processors. It should be possible to implement this bus with the MSP's GPIOs. Cheers TomKraut
  9. The most annoying part of the TI deals (for me) is that there never seems to be enough stock for interesting items. Living in Europe, I usually learn about the deals the next morning, and by then they are sold out... Cheers TomKraut
  10. Why not use a F53xx? It's a little more expensive, but it has two I2C ports, so depending on annual volume, the much shorter development cycle might offset the higher cost. Multimaster I2C would be an option, but that would require that the original I2C master is aware of it. And if it were possible to make changes to the original master, an additional translation device would not be needed... Cheers TomKraut
  11. For the low-speed peripherals (RTC, poti, possibly EEPROM) I would prefer I2C. The addresses make it easier to use them all at the same time and still have a lot of GPIOs available. Is there a specific reason (besides speed) that you prefer SPI? Oh, and just to make sure: by 4" x 4" you mean 10cm x 10cm, right? Cheers TomKraut Edit: The standard FT232R from FTDI should be enough for a simple usb-uart connection. The 4 GPIOs could be routed to headers for easy access.
  12. My mistake... I should have said openwrt, but I keep using the term uClinux whenever I think about Linux on routers, even though there is no more uClinux, since they integrated MMU-less support into the mainline kernel. Now, back to topic!
  13. Higher speed is one thing. But what I really like about the FTDI ICs are the Windows drivers. They have an API which allows you to detect which one of the 30+ virtual COM ports on your system is the one you're looking for, among other things. Makes throwing together a quick'n dirty GUI with C# so much easier...
  14. Launchpad, Fraunchpad, some low cost STM32 kit they were giving away at Embedded World last year and some BeagleBoards ... oh yeah, and a D-Link DIR-300, still wrapped, which is supposed to be my uClinux playground. BeagleBone looks really tempting, although it has no NAND, but I just don't have the time. And the Raspberry Pi, of course! But most of all, I want a PandaBoard ... and the time to play with it Cheers TomKraut
  15. Seems by "ideal" they mean "theoretical, with no self discharge" Cheers TomKraut
  16. Awesome idea! Might I suggest a FTDI instead of RS232? Most of the time one would have to use a serial-usb converter anyway... and of course, a prototyping area can never hurt! Cheers TomKraut
  17. Sergio's code won't compile on CCS, it's written for mspgcc. For lastaid's code to work, you have to change TIMERA0_VECTOR to TIMER0_A0_VECTOR, as it has a different name in the include file. Whenever something like this happens (interrupt vector names aren't recognized), check the include file. Especially the timers are well known for causing headaches Cheers TomKraut
  18. I only read the first two pages of the PRD doc so far. Seems to be a very easy to read paper on a very dry and tedious (for me ) topic. Downloaded to Kindle for some bedtime reading Cheers TomKraut
  19. The 1nF cap has nothing to do with programming. It is just there to prevent an MSP from resetting due to external effects like ESD. I never use it on a bread board, and of course it works, but I would always include it in a final design... a lesson I learned the hard way Cheers TomKraut
  20. Does the free XDS100 license also work with the stand-alone XDS100v2 emulator tool? https://estore.ti.com/TMDSEMU100v2U-20T-XDS100v2-JTAG-Emulator-20-pin-compact-TI-connector-P1848.aspx Or is it only for the XDS100 integrated on the evaluation modules? Cheers TomKraut
  21. When you need Ethernet on a MCU, it might be a good idea to use a MCU with Ethernet capabilities... like the Stellaris 6000 series. They are not much more expensive than a big VL MSP430 and an enc28j60, and you have everything in a single chip, as well as many, many example applications including tcp/ip stacks. Cheers TomKraut

    MP3 Player?

    Why would you want to do this? Just for the challenge? If so, I don't think there are any more "modern" ICs out there which you can buy ... decoder chips like this are just not an interesting market anymore for companies who sell their products through Digikey etc. If you just want to build your own MP3 streaming appliance, there are a couple other ways I would much more prefer than using a MSP430: - Use a Linux compatible router. You have WiFi, enough processing power to do the decoding and you can add Audio via USB. - Use an ARM SoM running Linux. You can add WiFi via USB. - Use an

    RGB LED Lamp

    You're looking at 3.6W maximum power dissapation here. I don't really know if you need a heat sink, but if not, you might need thermo vias to get the heat to the bottom layer. Now, the only thing missing here is a Bluetooth connection and an Android App to control the color Cheers TomKraut
