Awesome. I hadn't noticed that corner before. It's actually pretty easy to get apart with just thumbnails. Thanks!

So, I got this ez430 at the beginning of the semester but never got a chance to play with it. I just finished finals, and now I'm trying to figure out how to get the darn case off. I don't want to break it, but it doesn't seem like it wants to come apart even though it is obviously designed to do so. Any hints/tips?

Wow. I don't know what the launchpad is actually selling for in the UK, but

While it is not my project, hack a day has a link to a project the Ubiquitous Computing Lab at University of Washington called SNUPI. SNUPI stands for sensor nodes utilizing powerline infrastructure and uses the f2013 mcu. Thought some of you might find this interesting. It's nice to see the 430 in use in this application!

I have to agree, it's very tasteful and unobtrusive.

Goodspeed not Goodman

Same here. I've also entertained thoughts of creating library during the learning process but I don't yet have enough experience to know what material would be suitable. The MSP430 is the first opportunity I've had to program a uc and I'm loving the experience.

Wow. I've been trying to keep my two cents to myself, but after a few days of seeing updates in this thread I just can't anymore. If someone creates a library that simplifies things for the amateur programmer, how is that a bad thing? Sean, I understand your stance, but you seem to have forgotten that there isn't (and never will be) legislation or armed guards to force people to learn all the low level stuff about a thing. For example: to drive a car, must I be forced by the auto industry or the government to know what pistons are or how many camshafts are in my car's engine? Some

Thanks for this! I think I read somewhere what the difference on the launchpad was with/without the crystal. Of course, now I can't find it. Anyone?

I've never heard of this pull-up/-down resistor thing until all this. Now let me know if I don't have even a slippery grasp of this, but I've been assuming that enabling the resistor prevented p1.3 from getting a high enough signal to trigger the interrupt. BTW, I love this bit:

Since my initial problem is solved, I just wanted to thank you all for your help. I've learned a good bit so far, but have even more to learn. I'm sure you'll continue to hear from me as I progress along this path. Thanks!

So... how is it that enabling the pull-up resistor for p1.3 causes the interrupt not to occur more than once? And does enabling P1REN for p1.3 use a resistor other than R34 (from bluehash's schematic)?

Well, I seem to have solved this problem. There were a number of problems with the code I was using and the solution leaves me somewhat perplexed. @boseji: There was no issue with the WDT, although I still don't really know what that is. I test my program with and without the code you pointed out, and it works the same both ways. I removed it since I don't know what it does yet. I had just been overlooking it until you mentioned it; thanks. @GeekDoc: from what I've discovered thanks to beretta's tutorials, you are correct in your comments. The thing that is puzzling me right

Where do you think I would find the register definitions? What schematic are you referring to? Interestingly, your suggested modifications both did and didn't work. Using CCS4, if I Debug the project and choose "Run", it works as expected. However, if I choose "Free Run" or if I just power up the board with my program on the msp430, the button only responds once until I hit reset, as before.

Perhaps not... I really don't know what I'm doing with these interrupts, I've just hacked together something that looks like it might work from what little understanding I have and from my intuitions about copy and pasting other code into my program. Speaking of copy/paste, here is the code I'm using. Let me know if there is anything else that I'm doing wrong or if you don't know what I'm trying to do on a line or something. //****************************************************************************** // Hello LaunchPad // A simple program to get familiar with the MSP430. // I j
