Hi,
I am connecting external crystal of 32768Hz to pin XIN (P2.1)and XOUT(P2.0) but code gets stuck because of OFIFG always high.
following is my initialization code
_______
P2DIR = 0xFF; P1SEL0 = BIT4 | BIT5; // UCA0…
Part Number: MSP430FR2422 Hello,
Is there a variation of the MSP430FR2422 that has a storage temperature that goes down to -54 degrees C? If not, is there a similar MSP430 that would meet that non-operating temperature rating?

Hi all;
In MSP430FR2422 Data Sheet, we can see this figure.
This Figure shows 0.5MHz DCO when DCO=0, and 1.2MHz DCO when DCO=511 while DCORSEL=0, DISMOD=1, DCOFTRIM=0.
But in Table of DCO Frequency, 0.5MHz DCO when…
Part Number: MSP430FR2422 Tool/software: I'm working on a project with MSP430FR2422 microcontroller, which is used sense 4 Analog Inputs (A0, A1, A2 and A3). I need to monitor the result of each ADC in real time on "expressions" window of CCS. I'm using…
Part Number: MSP430FR2422 Hello,
We are using MSP430FR2422 as an RTC. We have configured LPM 3.5 with wakeup source as RTC overflow. We check the source of wakeup by reading the SYSRSTIV location which returns the value 0x08(i.e wake up from LPM3.5…
Part Number: MSP430FR2422 Hi,
I am using a variable called timestamp to keep track of time in seconds. This variable has to be updated every second. Can I use #pragma PERSISTENT and store the value of the variable in FRAM.
If yes, how many write cycles…
