class	ws_ledc_servo
	High-level driver for servos for ESP32/ESP32-Sx/ESP32-Cx. This driver implements a subset of the functions within the Arduino servo library, (https://github.com/arduino-libraries/Servo/blob/master/src/Servo.h). More...

Macros
#define	MIN_PULSE_WIDTH   544
	The shortest pulse sent to a servo.
#define	MAX_PULSE_WIDTH   2400
	The longest pulse sent to a servo.
#define	INVALID_SERVO   255
	Flag indicating an invalid servo index.
#define	DEFAULT_SERVO_FREQ   50
	default servo frequency

LEDC_TIMER_WIDTH

#define LEDC_TIMER_WIDTH   12

timer width to request from LEDC manager component, in bits (NOTE: While ESP32x can go up to 16 bit timer width, ESP32-S2 does not work at this resolution. So, for the purposes of keeping this library compatible with multiple ESP32x platforms, the timer width has been scaled down to 10 bits and the calculation adjusted accordingly)
