need help for motor pwm
PostPosted: Thu Nov 26, 2009 8:26 am     Reply with quote
Anybody can explain following command?
Want to use dspic30f3010.
Code:

setup_motor_pwm(pwm,options, timebase);
setup_motor_pwm_duty(pwm,unit,time)
set_motor_pwm_event(pwm,time)
setup_motor_unit(pwm,unit,options, active_deadtime, inactive_deadtime)

What is time base ? Is it frequency or on period?
What is unit?
What is mean set_motor_pwm_event(pwm,time)?

thank you.

These functions are only available for the PCD compiler. Most people
on this forum who answer questions, do not have that compiler.
For more information, read the following document:

Also, your version of the compiler may have bugs with those functions.
