Hello there, I have been trying to use a MSP430FR5969 to start a serial communication with a SARA-R4 Cellphone modem. Basically that modem just works sending AT commands through serial communication, so, i decided to start with the basics using the library example include <SoftwareSerial.h> SoftwareSerial mySerial(P1_4, P1_3);// RX, TX void setup(){ // Open serial communications and wait for port to open: Serial.begin(9600); Serial.println("Goodnight moon!"); // set the data rate for the SoftwareSerial port mySerial.begin(9600); mySerial.println("Hello, world?");

is it possible to underclock or overclock the device? i mean, for example i need it just to use 50% of it's power, is there a way to it limit itself to a specific configuration? i want the msp432 to take as much low power as possible(will be battery powered)

I'm new to MSP430 and I'm trying to do a frequency/period measurement. I've read about timers and get the main concepts though I'm still learning. To get an idea of how they work, I'm using this code. It outputs a PWM on one pin which I connect to another pin for capturing period: http://coecsl.ece.illinois.edu/ge423/datasheets/MSP430Ref_Guides/Cexamples/MSP430G2xx3 Code Examples/C/msp430g2xx3_ta_21.c After making some modifications (removing unneeded code to light led and adding calculations for frequency) it works with the original pins. However, I want to change which input pin will t

Hi, I tried my hand for the first time on a servo and my experience may be helpful to other people. Servos are controlled by the length of a pulse. This pulse is repeated ca. every 20mS. The pulse length can vary coarsly between 1 and 2 mS. The pulse length determines the rotation angle. If the servo starts up, it goes to a middle position, corresponding to a ca. 1.5 mS pulse. For shorter pulses the servo turns in one direction, for longer pulses to the other. The range is limited, mostly to +/- 90 degree, the accurate values depend on the servo, as does the min/max widths. Mine had a ran

Just as an FYI - I was concerned about using the built in DCO in the FR5969 for UART because the spec sheet says although it's factory trimmed, it's still +/-3.5%. Generally it needs to be within 2% for a UART to work correctly so I measured the two FR5969's I have on our 2.4GHz frequency counter and this is what I got. 2 is obviously not a big sample size, but the frequency trimmed DCO on the FR series looks pretty good @ room temp and 8MHz or under. I found another doc from TI that's a comparison between F5xxx and FR5xxx and it mentions the DCO is generally within 2% "within a restrict
