Davin, I'm glad to hear that you can use ACLK as a workaround. Does the issue exist if you don't use DIVA2 and set UCB1BR0 to 60? You may have the option of using LPM3 for less power consumption if you...

Hi Malia, We do not currently maintain any collateral for using a MSP430 to emulate a GPIO expander like the PCA9555 , however I believe that such functionality would be very easy to implement. You...

Hi, Sorry for the inconvenience. There is a bug in the RTC_C_disableInterrupt API. This should get fixed in the next driverlib version. In the meantime you could change this API (in rtc_c.c) to: void...

ADC reads time domain information so you don't need to find code where the frequency is showed but you want to find where it comes out of ADC. You shall search google first and find similar "self made...

You can use just onboard holes or tag-connect. http://forum.43oh.com/topic/9639-temporary-connection-for-sbw-flashing-without-socket-using-pads/

Not a connector to be exact but I love the stuff from http://www.tag-connect.com/ (With zrno soli having been 2 minutes quicker than me ;-))

Hi Ferlyn, The code you sent as is does not work because you still have TAIE set for TA1, which tries to access the TIMER1_A1_VECTOR ISR and causes the program to enter the UNUSED_HW_ISR loop. Since...

Did you enable WDT interrupt after 8 msec? If so, then it will interrupt main and try to execute the corresponding ISR. If not, then it will just set a flag after 8 msec and the main keeps running.

View ArticleForum Post: RE: What JTAG connections are used for the MSP430F5131?
Yes - does pin 8 of the tool's 14-pin connector need to drive the Test/SBWTCK pin on the -5131 to put the PJ.xx pins into JTAG mode?

We'll try SBWTCK in the lower range; we exceeded by a small amount to simulate the high-energy that we think is being imposed. For the rest... that will take some time, but we'll see what we can do,...
