  1. Hello guys,i have a question for my project im using the msp430g2231 microcontroller and i want to measure frequencies up to 10Mhz.Im new to microcontrollers(not programming),and im not sure how to make the overflow work void main(void) { WDTCTL = WDTPW + WDTHOLD; // stop watchdog timer BCSCTL1 = CALBC1_1MHZ; // Set range DCOCTL = CALDCO_1MHZ; // Set DCO step + modulation delay(100); // delay 100mS until next screen refresh /*** Timer_A Set-Up ***/ TA0CCR0 = SampleTuneTime; TA0CCTL0 |= CCIE; // Interrupt enable
  2. Hi all, I have recently found a sketch in arduino forum for frequency counting, which I tried running in MSP432 with energia and MSP430 with energia sketch on Code composer studio. The sketch basically counts the frequency using interrupts and prints the frequency on serial monitor but serial monitor is empty while running the program,.The sketch is as shown below, // Frequency counter sketch, for measuring frequencies low enough to execute an interrupt for each cycle // Connect the frequency source to the INT0 pin (digital pin 2 on an Arduino Uno) volatile unsigned long firstPulseTime;
  3. Hi all, I'm building a project in msp432 where I need to determine the speed of an object using doppler shift frequency based calculations.Is there any libraries or methods for calculating frequency precisely in the 1-100 Hz range?
