  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...
