  1. They put up great pin maps at energia.nu - http://energia.nu/pin-maps/guide_cc3200launchpad/(http://energia.nu/wordpress/wp-content/uploads/2014/09/cc3200lppinmap.jpg for the full res image) I believe you should be using 9 and 10 for SDA/SCL or TX/RX for Serial1. It looks like 39/40 are alternates - but I don't think that's the default configuration.
  2. Have you considered using serial? I have an MSP430 connected to Serial1 on the CC3200 which leaves Serial to communicate with your PC if attached (I use it for debugging output). The one issue I ran into - which may be your problem with I2C since it uses the same pins - the LEDs seem to screw things up. I had to specifically set the green LED pin (RX 1) as an input to get things to work, even though I didn't have to do that for Serial - it was needed for Serial1. I'm only receiving serial from the MSP430, not sending it back - but you might need to expressly set that pin as an output as we
  3. For the HC-SR04 with Energia - check out this post - http://forum.43oh.com/topic/2470-hc-sr04-ultrasonic-sensor-w-energia/ As I noted on that thread - the device is 5v - I wouldn't expect it to run correctly on the launchpad's VCC - you may see unexpected results. Looks like there is a lot of code on the forum for the TLC5940 with standard C, but not Energia. Searching through some of the threads may help though.
  4. I've kind of felt that spreading the communities across multiple domains kind of dilutes the discussion I'd almost love to see a TIMicros.com or something to bring it all together. The community has been pretty quiet lately - especially in comparison to when I started on the site a few years ago. I'd love to see what we can do to make it as active again. The POTMs were great - but the last few didn't get much participation. Maybe we should start a thread on what we can do as a community (not just @bluehash) to keep things going?
  5. I believe so - it's basically where the USB power comes in - and I've certainly hooked a USB power bank up to one of these boards before.
  6. I'm using a CC3200 to push data to data.sparkfun.com - using GET works just fine for me. I honestly haven't tried post, and whether or not it will work obviously depends a bit on the technology you have on the back-end. data.sparkfun.com is fine accepting GET, but if I was using WebAPI (.NET) - I'd have to set my methods to accept GET or switch to POST. client.println("GET /input/" + PhantStreams[2] + "?private_key=" + PhantPrivateKeys[2] + dataParams + "&temp2=0 HTTP/1.1"); client.println("Host: data.sparkfun.com"); client.println("User-Agent: Energia/1.1"); client.println("Connection
  7. FYI - the pins on the CC3200 don't provide enough current to run LEDs (or at least not without damaging them long-term). That's why the on-board LEDs use transistors.
  8. So I recently tried to get a solution up and going on Azure. Worked great until I realized that the lower-cost and free options were limited by CPU time (I think the "free" option was 5h) and the next level up with 100% uptime was $56 a month. So - scrap that idea. I might still see about doing something with .NET, but I'd have to set up a computer at home for cost purposes. I'm going back to sparkfun's Phant and data.sparkfun.com service. I've been working with @@Lgbeno a bit on his imp.guru site as well as some new stuff he's cooking up. Visualizations are great - gives me a way t
  9. If you edit the first post, you can edit the title. Make sure to click the "use full editor" button. That's an excellent point. I'd hate for someone to start with the blink example and write something that always stopped working after 50 days. That could be horribly frustrating. The concern I would have is that adding extra code to something as basic as a blink example to address the issue might confuse a beginner. I did some quick googling, and apparently there are a number of posts about this issue for Arduino as well - not surprising considering Energia is a fork of Arduino and m
  10. Nice to see someone talking about some of the problems behind the Arduino movement - and even better to see the Launchpad mentioned as an alternative. That's one of the biggest reasons why I've stayed away from Arduino - I prefer knowing everything that's going on. It's a big reason behind why I'm a software developer - I don't like relying on other people's software unless I can tear it apart
  11. For ease-of-use - I like using the BIT0, BIT1, etc. defines. Also - the reason why you're running into problems with initialization is you're always using the plain assignment operator. You need to look at some of the other operators like |=, &= and ^= - they will make it easier to control single bits without affecting the others. For instance - P1DIR |= BIT6 will only add bit6 to whatever is defined in P1DIR. Typical on/off code: void loop() { P1OUT |= BIT6; delay(1000); // wait for a second P1OUT &= ~BIT6; delay(1000); // wait for a secon
  12. Regarding the sleep time - Adafruit says you shouldn't query them more often than every second or two. They're not very fast devices. https://learn.adafruit.com/dht/overview
  13. Welcome to the forums! Make sure to post if you've got questions
  14. @greeeg I'll absolutely make some good things out of it! There isn't anywhere to pick up filament except the internet - still a problem in the US in most areas that I'm aware of. I've been meaning to test out some of the soft filament - excited to try that out!
  15. Got mine today! I'm assuming it's from @@greeeg ? 6 different types of filament (including some flexible ones), two dot matrix VFD's and several led matrices! Should be some great supplies for projects. Thanks to my secret santa!
  16. FYI - I don't think email notifications are working anymore. I stopped getting them two days ago.
  17. Wow @@bluehash - didn't realize you were getting married this weekend - congrats!
  18. Have you looked at Azure? Not sure what you need from a disk space/cpu/ram perspective. http://azure.microsoft.com/en-us/pricing/details/virtual-machines/#Linux
  19. Registers are available from the family user's guide - you can find it on the product page - http://www.ti.com/product/msp430fr5969 I always like the code examples that can be found on the tools & software tab - they're great for learning how to use one component of the chip at a time. http://www.ti.com/product/MSP430FR5969/toolssoftware For general programming - I'd check out the "Getting Started" thread. Let me know if there's something specific you're looking for - I'll try to help out. I've you're looking for something super easy - check out Energia. All of the registers
  20. @@abecedarian - I like to keep mine right around 600 for most work.
  21. Glad you like it @@ILAMtitan ! I had seen several projects with those large lego figures - figured if the clock didn't quite work - it was always worth hacking as well
  22. I'll have to check this out! I started work on a .NET solution myself a while back and haven't made it very far - I'll have to check out your solution. Thanks for sharing!
  23. Can you post your code? That would be the most helpful approach. A picture or diagram of your setup would be nice as well.
  24. I have - I had to find an interrupt-capable pin (ports 1 and 2). I don't think I had any trouble getting it working.
  25. Outside of the obvious power, reset, gnd, etc. - I believe so. You should also probably stay away from TX/RX as those are connected to the USB -> Uart bridge and will likely see problems.
