}Expand description
Higher-level PWM interface that restricts the user to a specific PWM pin. This is particularly useful for passing to capsules that need to control only a specific pin.
Required Methods§
Sourcefn start(&self, frequency_hz: usize, duty_cycle: usize) -> Result<(), ErrorCode>
fn start(&self, frequency_hz: usize, duty_cycle: usize) -> Result<(), ErrorCode>
Start a PWM output. Same as the start function in the Pwm trait.
Sourcefn stop(&self) -> Result<(), ErrorCode>
fn stop(&self) -> Result<(), ErrorCode>
Stop a PWM output. Same as the stop function in the Pwm trait.
Sourcefn get_maximum_frequency_hz(&self) -> usize
fn get_maximum_frequency_hz(&self) -> usize
Return the maximum PWM frequency supported by the PWM implementation.
Same as the get_maximum_frequency_hz function in the Pwm trait.
Sourcefn get_maximum_duty_cycle(&self) -> usize
fn get_maximum_duty_cycle(&self) -> usize
Return an opaque number that represents a 100% duty cycle. This value
Same as the get_maximum_duty_cycle function in the Pwm trait.
