Peripheral pwm class

C++ defination code:
class PWM

def __init__(self, id: int, freq: int = 1000, duty: float = 0, enable: bool = True, duty_val: int = -1) -> None

PWM constructor

item	description
type	func
param	pin: direction [in], pwm id, int type, like 0, 1, 2 etc. freq: direction [in], pwm frequency, unit: Hz. int type. default is 1000 duty: direction [in], pwm duty. double type. range is [0, 100], default is 0. enable: direction [in], enable pwm output right now. bool type. default is true, if false, you need to call enable() to enable pwm output. duty_val: direction [in], pwm duty value, int type. default -1 means not set and auto calculate by freq and duty. This arg directly set pwm duty value, if set, will ignore duty arg. duty_val = duty / 100 * T_ns, T_ns = 1 / freq * 1000000000.
throw	If args error or init pwm failed, will throw err::Exception
static	False

C++ defination code:

PWM(int id, int freq = 1000, double duty = 0, bool enable = true, int duty_val = -1)

def duty(self, duty: float = -1) -> float

get or set pwm duty

item	description
type	func
param	duty: direction [in], pwm duty, double type, value in [0, 100], default -1 means only read.
return	current duty, float type, if set and set failed will return -err::Err
static	False

C++ defination code:
double duty(double duty = -1)

def duty_val(self, duty_val: int = -1) -> int

set pwm duty value

item	description
type	func
param	duty_val: direction [in], pwm duty value. int type. default is -1 duty_val > 0 means set duty_val duty_val == -1 or not set, return current duty_val
return	int type when get duty_val, return current duty_val, else return -err::Err code.
static	False

C++ defination code:
int duty_val(int duty_val = -1)

def freq(self, freq: int = -1) -> int

get or set pwm frequency

item	description
type	func
param	freq: direction [in], pwm frequency. int type. default is -1 freq >= 0, set freq freq == -1 or not set, return current freq
return	int type, current freq, if set and set failed will return -err::Err
static	False

C++ defination code:
int freq(int freq = -1)

def enable(self) -> maix.err.Err

set pwm enable

item	description
type	func
return	err::Err type, err.Err.ERR_NONE means success
static	False

C++ defination code:
err::Err enable()

def disable(self) -> maix.err.Err

set pwm disable

item	description
type	func
return	err::Err type, err.Err.ERR_NONE means success
static	False

C++ defination code:
err::Err disable()

def is_enabled(self) -> bool

get pwm enable status

item	description
type	func
return	bool type, true means enable, false means disable
static	False

C++ defination code:
bool is_enabled()
