|
必须先创建 Brain 或 3-Wire Expander,然后才能使用 pwm_out 类构造函数创建对象。
// Create the Brain.
brain Brain;
// Construct a Pwm Output "pwm" with the Pwm class.
pwm_out pwm = pwm_out(Brain.ThreeWirePort.A);
This pwm
object will be used in all subsequent examples throughout this API documentation when referring to pwm_out class methods.
类方法#
state()#
The state(value, units)
command sets the state of the PWM.
