  1. Something similar that turns out to be false positive happened to me as well on an Altera tool (forgot which exe) and also some cuda executables compiled from source.. Checked the latest Energia (fresh downloaded energia-0101E0017) with two anti-virus, avast and McAfee, and found no threat.

  3. Yes, something smaller than the LaunchPad form factor, one even slimmer than the USB dongle style F2013 dev stick, like this: This could be a deviation from the LP line, but: 1. A form factor like this is definitely great for USB gizmos 2. Easier to be accepted by someone completely new to MCU than a development board 3. Greatly reduce packaging, can even probably be shipped in envelops (no USB cable needed), to get someone a taste of programming an MCU (even though it is just a blink of LED as out of the box experience), and arouse their interest to move on to the LP dev boards.
  4. Fmilburn, no kidding i almost cried when saw your photo. I am sure to have one of these,with a very white nice plastic cover bag about 20 years ago (although in my memory that plastic cover was meant to be discarded once opened). DOS became Windows 3.1 became Windows 95 became Windows 98 became Windows XP became Windows 7 became Windows 8 became Windows 10. Mine disappeared somewhere along the number / char change, but the memory of my pencil following this flow chart template will stay with me forever. Thanks for posting this!
  5. Hello Blipton, I have not used BlueMix nor Node-RED, but for the usage of simple hosting I'd highly recommend Amazon AWS. There is an offer of free-tier for 1 year of use. You may want to read this link. The terms are quite complicated but in brief: 1 year free VM running time enough for 24x7 non-stop for 365 days from my experience enough bandwidth for personal use, occasionally may get charged for a few cents for moving VM around and large downloads, but that's very rare. required a valid VISA card to create account (just in case the free-tier quotas are exceeded, the charges will apply
  6. The LaunchPad is a great platform. Since the original 2231 device it has been my first choice for hobby projects. In fact, through playing, er, working with the LaunchPad I learnt much of my knowledge in MCU and electronics. The information from TI about the MCU device as well as the launchpad itself, in the form of documentation and engineers' replies to questions, are always helpful, accurate and consistent. Apart from LaunchPad I am also fan of TI calculators, and am very excited to see the upcoming release of the LaunchPad based Innovator System. The package looks great and if TI could
  7. Since my only 5529LP was confirmed no longer functioning properly and the likely cause is the USB hub module, there have been some thoughts going through my mind to salvage the core 5529 device on the LP for some good use. And this weekend I have decided to give it a try. As the USB host part is confirmed not functioning, the first step is to verify the F5529 is still good. The easiest way is to try program it and check if it can run new program. With a good F5529 LP (the new replacement board ordered after the old one retired), I removed all the jumpers between the ez-FET and the targ
  8. I'm with you absolutely, Beowulf is a very solid example. Honestly, while I'm not against buzzwords as explained, I feel the same as you do when seeing cloud of this and that, all over the Internet. The choice of word "Cloud" is exceptionally bad, consider most of us prefer a sunny day over raining
  9. In my humble opinion, these are like fashion of what we wear. It changes every so often, when someone with evangelistic mind and power of some sort (be it economic or established in certain field of the society) coined a term, marketing people found potential, and there we go again. Please don't get me wrong, by buzzwords I have no negative meaning to these terms (as they bear serious definitions behind and appears on academic papers), but merely describing these on perspective suitable on this topic. Yes they tend to be overused with a vague definition, but on the bright side they are not
  10. Yes! Like this idea! It's still a damn good 5529 mounted on a very nice board with good connectors. Interestingly on the same line, my wife asked yesterday, after learning that I believed only the hub part is not working, if the LP can be cut and replaced as she saw the dotted line printed on the LP . (And she is not from engineering background).
  11. The LP finally retired last week. Won't even power on. Plugged into PC directly and it cannot recognize the device. The replacement LP delivered today, and my desk companion is back again I believe only the USB hub part of the old board is failing, and the rest including the 5529 should still be good. Wrapped it properly and perhaps one day it can be of some good use. Btw, the old one is LP Rev.1.4 and the new is 1.5. The screw holes of the new one is much easier to work with as it is less tight. Screwdriver is already needed halfway on the old one, but for the new one only
  12. Ok I think it is likely the connector on the LP, or the parts nearby. It has been on and off today, that makes me think the emulator chip should still be ok, and therefore tried what the Russian cosmonaut did in the movie Armageddon - knocking. Knock on the right side, nothing, the left side, occasionally the LP resets! Sometimes after reset the serial worked. As I'm facing the back of the LP with the USB connector on the upper left hand side, I tried to monkey with that. Although not 100% of the time, the LP resets when the cable is moved, so that's the culprit! This will also explain
  13. Woke up and it's gone again.. tried to dry it with a hair dryer but still nothing. Perhaps it's time to order a new LP [Edit] It worked again! It magically talked to exosite again after a few hour of silence on the serial since powered on.
  14. Yes it is weird, it has been always on the desk undisturbed, I have no scope to test so am only able to diagnose the problem to the serial / program part without any further conclusion. Since it stopped sending data I kept turn it on for it can still display temperature data on the LCD. Today is like usual I didn't touched it but before dinner noticed the timestamp is back on the LCD which means it come back! I was always thinking the ezFET emulator just gave up and expired, until you mentioned environmental factors, which reminds me of high humidity recently. Highlighted below is over 90%
  15. 2 years ago I had a small project using a F5529 LP with TMP006 sensor booster pack, connecting to an OpenWRT router using serial to send data to ti.exosite.com, and also a 16x2 LCD readout. Last month it suddenly stopped sending data. Trouble shooting confirmed the problem is at the serial part on the LP. The LP also refused being re-programmed during the trouble shooting tests. The F5529, TMP006, and OpenWRT are all confirmed working flawlessly. Another lost feature is the ability to show time on the LCD which it retrieves from exosite everytime data is sent successfully. A nice clock als
  16. https://education.ti.com/en/us/products/micro-controller/ti-innovator/tabs/overview A new dev kit with RGB LED, light sensor, talks to TI calculators, and a nice enclosure! Available Fall 2016
  17. Keep getting error message in CCS saying unable to program the LP (not exactly but something very similar to that meaning). 100% sure the board is connected. Unplugged the USB and plugged in again, restarted CCS and restarted PC. Turns out I tried to program a non-existent 2553 as I moved it out from the LP to a breadboard
  18. I'm with you. Struggled between these two when my old Casio retired, tried the emulators for both, the 89 is much more "calculator-like". The Nspire, on the other hand, is like a hand-held Mathematica or Maple, yet I found myself made less input mistake with it, perhaps due to the equation display. But yes, the OS features like UI and file system, sometimes bog down the machine. If I knew back then the TI Sensor Tag works with the iPad version of the Nspire, the choice will be clear - get an iPad and a 89 instead
  19. The TI nspire calculator is an advanced calculator which is expected to be the successor of TI-89. There are news on the web that a recent OS update (version 4.2) to the TI Nspire calculator added serial interface support to its programming environment. Before this OS release, the USB port is intended only for PC data connectivity (PC software for this calc is free with every purchase of the calc, and runs exactly the same as the real calculator on PC) and charging of calculator battery. Although this feature is not highlighted in the release notes, some calculator enthusiasts reported
  20. Thanks Greeeg for the correction, yes I meant to say "The Martian". Sure i was somehow time wrapped after the movie
  21. Just watched The Martian. Great movie. Amazed with the "chemist" Mars expedition team member who was requested to make a DIY explosive device in about half hour's time that features: - USB power - timing with RTC for count down (not sure about this as someone announced power up panel something before the device is triggered) - guaranteed to work giving the condition they are facing - professionally done that doesn't look DIY at all Yeah it's movie but still.. it is the spirit that we care about. Good DIY job! Btw Matt Damon is so special! He got rescued every time in the big
  22. The forum I read everyday is back! It feels like faster from here (the other side of the globe).
  23. Thanks for the input! Yes I thought about Lego too, but not privileged to be Lego enthusiasts, I went to check out but can only saw the Technics series that are $$$ and not even sure I can make something out of it apart from what the diagram shown.. Will definitely look for junk printers.. and maybe CD - ROMs are ok too? Thanks for the tips, save time screening out the vast search results This will be the perfect platform I envisaged (from http://volterainc.com/ ): Yes I agree if it is 3D printer, I'd definitely get one.. in fact got some planning to mount a mi
