.SH "NAME"
pwm_get_relative_duty_cycle \- Get a relative duty cycle value
.SH "SYNOPSIS"
.HP \w'unsigned\ int\ pwm_get_relative_duty_cycle('u
.BI "unsigned int pwm_get_relative_duty_cycle(const\ struct\ pwm_state\ *\ " "state" ", unsigned\ int\ " "scale" ");"
.SH "ARGUMENTS"
.PP
\fIstate\fR
.RS 4
PWM state to extract the duty cycle from
.RE
.PP
\fIscale\fR
.RS 4
target scale of the relative duty cycle
.RE
.SH "DESCRIPTION"
.PP
This functions converts the absolute duty cycle stored in
\fIstate\fR
(expressed in nanosecond) into a value relative to the period\&.
.PP
For example if you want to get the duty_cycle expressed in percent, call:
.PP
pwm_get_state(pwm,
state); duty = pwm_get_relative_duty_cycle(state, 100);
