According to the experimenter board User Guide (http://www.ti.com/lit/ug/slau343b/slau343b.pdf), "The MSP-EXP430FR5739 FRAM Experimenter Board kit includes the following:

Well, shame on me for not reading DNP. I am embarrassed. Regarding the software-selectable load capacitors, I see that my launchpad (with msp430g2553) has xcap settings, but the fraunchpad (msp430fr5739) does not. (Family User's guide http://www.ti.com/lit/ug/slau272b/slau272b.pdf) Does this mean I should solder the two appropriate surface mount capacitors on c22 and c21? http://www.ti.com/lit/an/slaa322b/slaa322b.pdf

Video proof, stuck with VLO until... Tap Tap... o_O The wire I use is just a simple wire lol... nothing is connected on the other end. I would like to note that I was out of ideas when I decided to tap the XOUT with a random piece of wire to see this change. Microcrystal that came with the board: http://i.imgur.com/3U3SzqB.jpg How I soldered it: http://i.imgur.com/Ay9LMOM.jpg I wouldn't think that I would need to increase the load. They packaged this crystal with this board, so I was hoping that I could merely use it right off the bat. The following shows the capacitors (12pF)

Haha... I read it in the Family User's guide... like others and you have said, it is very useful. It is a learning process. I set a command to clear the fault. Illogically, if I just get a random piece of wire, tap XOUT from the microcrystal pin, the fault clears... yep... sigh.

Thank you all for your suggestions. I will look into them as I tinker more with the MSP430.

Well, I understand why I was reading a freq of around 8-9kHz. There is a failsafe that if there is a fault with the external crystal, VLO (typically between 8-10kHz) is automatically used instead of the external crystal. Thus, the 8-9kHz kicks in. ( ) I confirmed this by setting clock from VLO instead and measured from my oscilloscope. Sorry for any misunderstandings, before, I did output the microcrystal to ACLK and then read ACLK from a pin. My oscilloscope shows the correct frequency once in a blue moon. http://i.imgur.com/R2NeelP.jpg As for why such a fault is happening... I do

Thank You! I lowered the timer clock and now receive measurement readings where I expect them to be. I have one question though, sorry if this is offtopic. I happen to also have a Fraunchpad, and I tried to perform the same operation (after looking at more example codes and editing the proper pins/registers). It works!!! There is one slight gimmick. I soldered on the 32.768kHz microcrystal that came with the board to use for my timer clock. Would there be any reason, other than the divider, that my crystal is outputting 1/4 of expected 32.748kHz? I outputted the signal from my crystal to a

Thank you, I have recently been reading MSP430 Microcontroller Basics by John Davies, other tutorials by google search engine, and some guides/blogs linked on this board. The Family User's Guide that corresponds to my chip along with looking at example codes in the MSP430Ware has been very helpful in understanding the basic operations. My area is mainly power electronics and power systems. My programming background is very limited. I took a C++ class freshman year and then had some Verilog and MIPS programming; however, it is no where near enough to be considered proficient. Thank

Hiya, Atm, I am a EE student and attempting to learn how to use msp430 instead of using an Arduino for low-powered applications. I just started looking into msp430 a month or so ago. I have read some helpful stuff from the thread "Best information for those new to the MSP430?" and looked at some blogs. I am in your care.

Hello all, I am new to programming in general. I was wondering if you can help me out by explaining a simple concept of timer capture measurement. I am using a launchpad with a msp430g2553. I started out by using the period measurement example from MSP430ware, file msp430g2xx3_ta_21. When I input a 30Hz square wave signal into P1.2, I get period around 3850 on my watch expression. The period is calculated by subtracting the time of one rising edge from the previous rising edge. Can you help explain this number to me? Does it have to do with overheads? The Timer A is set up with SMCLK at
