Example using motor PWM with DSPIC30F2010

Posted: Mon Dec 23, 2013 8:41 pm

Example using motor PWM with DSPIC30F2010:

Just for sharing with people who needs it:

It´s a little confuse understanding how motor pwm works, but, for example, it is possible to adjust it for several configurations.

In the example below I set it for generating two different PWM with inverted outputs. The other 4 PWM pins of DSPIC30F2010 remain disabled(can be used for others things or io ports).

Code:

//MOTOR PWM(using example)

setup_timer1(TMR_INTERNAL,3333); //setups PWM frequency
setup_motor_pwm(1,MPWM_FREE_RUN,1,0,255); //setups PWM
//
set_motor_unit(1,1,MPWM_ENABLE_L,1,1); //setups first PWM
set_motor_pwm_duty(1,1,20); //Adjusts first pwm duty
set_motor_unit(1,2,MPWM_ENABLE_L,1,1); //setups second PWM
set_motor_pwm_duty(1,2,100); //Adjusts second pwm duty

Good luck folks!! ;)
Have a very merry Xmas *<:o)
