  1. Have you read the system integration manual for the GSM radio? if not, give it a read here (pay close attention to chapter two). The GSM radio is fairly picky. Are those sensors on breakout boards? That's all i can see right now, i'll take a more detailed look later. Design I'd recommend adding a reset switch for your MSP430. You need ESD protection for the SIM card. Any reason you need or want the DHT22? I really don't trust that sensor line for accurate measurements. Switch your UART line! It should look like this: _MSP430__ _GSM RADIO_ |
  2. Have you considered turning it into a pulse oximeter? You just need to add another LED/Photodiode pair in red along with an additional AFE.
  3. Do you mean a rule sheet specific to the MSP430 or a rugged MSP430 development board? In any case, replacing the MSP430 or launchpad might be a cheaper solution. Wouldn't a darlington transistor pair work as well?
  4. Hi bluehash, I'd like to help out with the wiki.
  5. There isn't any device crippling bugs, but there are some that may be annoying now and perhaps later in the future. But Just out of curiosity, Did anyone get a XMS430G2231 or XMS430G2211 when the MSP430 value line LaunchPad first came out? The only development/eval kit from TI that had experimental silicon was the Chronos.
  6. You can try returning the launchpad, since you have a LX4F and not a LM4F. "Should this evaluation board/kit not meet the specifications indicated in the User’s Guide, the board/kit may be returned within 30 days from the date of delivery for a full refund." (See http://www.ti.com/lit/ml/sszz027b/sszz027b.pdf)
  7. I was hoping for a uncut panel, but these should do fine in a frame. Thanks LariSan & Bluehash.
  8. I thought we were ordering panels to begin with?
  9. I think i will frame one of them. My question is, do you get PCB cutouts or a whole panel (Please let it be a panel )?
  10. The tolerance of the crystal provided with the launchpad is +/-20ppm (or 0.002%). It's not the best, but it works.
  11. I'd be willing to write user manuals for boosterpacks, if anyone is interested...
  12. I ordered this one. You can find others by going to the analog products, then sort by lowest price. five or so free boards will come up, along with lots of $5 boards. The boards are 'demonstration fixtures'... But i'm sure they can be hacked for other unintended purposes.
  13. I just ordered a 'free' bare breakout board along with the Stellaris boards. The breakout board shipped the same day.
  14. /* Bluehash & Moderators: Double post, Please remove */
  15. s1ck, The default reference voltage for analogRead() is well, DEFAULT (Which is using the internal VCC and VSS). It can be changed by using the function analogReference(). As for reading the exact reference voltage, I don't think that's possible. (Other than setting the ADC10 to output the reference voltage and using a voltmeter to read it)
  16. Did they forget about my order or something?
  17. Seems like the first Wolverine MSP430, MSP430FR5969 just came out. (or has been out, and i just didn't know about it)
  18. I will be using the 43oh! MotorPack thread instead of this one on Stellarisiti. Makes it a whole lot easier for me, and probably for you as well.
  19. Added address select logic into design, which should hopefully allow users to stack another motorpack onto the launchpad and use both at the same time.
  20. [bug5] It appears that phpbb doesn't really delete private messages, so every message from the old board was transferred to this one, overfilling our PM boxes and not allowing us to send or receive PMs. [Request1] Is there any way to archive those messages, so we don't have to permanently delete them? Or even better, increase the quota? [Request2 or Bug6] It appears that uploading is not allowed. Can you lift that restriction? "You can upload up to Uploading is not allowed of files (Max. single file size: 2MB)"
  21. Incredible work. Are you going to put epoxy the IC?
