Msp430f149 microcontroller controls stepper motor C language program [Copy link]

#include     typedef unsigned int uint; typedef unsigned char uchar; #define PWM BIT2 void int_clk() { uchar i; BCSCTL1&=~XT2OFF; //Turn on the XT oscillator BCSCTL2|=SELM1+SELS;//MCLK 8M and SMCLK 1M do { IFG1 & = ~OFIFG; //Clear the oscillation error flag for(i = 0; i < 100; i++) _NOP(); //Delay waiting } while ((IFG1 & OFIFG) != 0); //If the flag is 1, continue to loop and wait[ IFG1&=~OFIFG; } void int_pwm() { P1SEL|=PWM; //Select P12 as PWM output P1DIR|=PWM; TACCR0=800; //PWM signal period 10KHz TACCR1=400; //Duty cycle 1:1 TACCTL1=OUTMOD0+OUTMOD1+OUTMOD2; //Output mode selection TACTL|=TASSEL1+MC0; } void main() [size =4]{ WDTCTL=WDTPW+WDTHOLD; //Turn off the watchdog int_clk(); //Initialize the clock [size=4 ] int_pwm(); //Initialize PWM while(1);//End } This routine is based on The PWM of the msp430f149 microcontroller controls the rotation of the stepper motor, with P1.2 port as the PWM output port, the PWM signal cycle is 10KHZ, and the duty cycle is 1:1.
