Hello,
i´m trying to make function the motor control PWM module and i have no answer from my dspic33fj128mc802.
| Code: | setup_motor_pwm(2,MPWM_FREE_RUN | MPWM_SINGLE_PULSE, 1000);
set_motor_unit( 2,MPWM_INDEPENDENT , MPWM_FORCE_L_1,MPWM_FAULT_NO_CHANGE,0);
set_motor_pwm_duty(2,0,0xfff);
set_motor_pwm_event(2,1000); |
The compiler does it right, but in the pins there are no answer. can anybody help?
And finally, I don´t understand the functions (setup_motor_pwm(), set_motor_unit(), etc) well, so if anybody has experience in it, please explain as you can.
Thanks. |

Do a search for setup_motor_pwm in the forum's search page:

There are some previous threads on this topic.
Always post your compiler version. |

That´s it, i found the solution!. The sample code from the manual is wrong, so don´t read it if you want to make it run. The parameters are bad written.
An example code that works is
| Code: | setup_motor_pwm(1,MPWM_FREE_RUN , 10000);
set_motor_unit( 1,1,MPWM_INDEPENDENT | MPWM_ENABLE | MPWM_FORCE_L_1,0,0);
set_motor_pwm_duty(1,1,1000); |
Thanks. |
