Remote Controlled Servo (RC Servo)

Soft Driver

Defined in namespace hal::soft

#include <libhal-soft/rc_servo.hpp>

class rc_servo : public hal::servo

Generic RC servo driver.

Public Static Functions

static result<rc_servo> create(hal::pwm &p_pwm, settings p_settings)

Factory function to create a rc_servo object.

Compile time error will occur if the min microseconds is more than the max microseconds, if the max microseconds is more than the frequency wavelength, or if the min angle is more than max angle.

Parameters:

• p_pwm – - pwm signal connected to the RC servo

• p_settings – -

Returns:

result<rc_servo> - Constructed rc_servo object

struct settings

Information about the RC servo needed to control it properly.

Public Members

hal::hertz frequency = 50

PWM signal frequency. Check the documentation for the RC servo to determine what range of frequencies can be used with it.

hal::degrees min_angle = 0

The physical minimum angle that the servo shaft can move to.

hal::degrees max_angle = 90

The physical maximum angle that the servo shaft can move to.

std::uint32_t min_microseconds = 1000

The minimum pulse width in microseconds that maps to the minimum angle of the servo.

std::uint32_t max_microseconds = 2000

The maximum pulse width in microseconds that maps to the maximum angle of the servo.
