enable_servo()

esp_err_t enable_servo

(

)

Enables Servo port on the sra board, sets up PWM for the three pins in servo port.

Returns

esp_err_t - returns ESP_OK if servo pins initialised, else it returns ESP_ERR_INVALID_ARG

enable_servo_helper()

esp_err_t enable_servo_helper	(	servo_config *	config,
		mcpwm_timer_handle_t	timer,
		mcpwm_oper_handle_t	operator
	)

read_servo()

int read_servo

(

servo_config *

config

)

Get the angle of the servos.

Returns

esp_err_t

set_angle_servo()

esp_err_t set_angle_servo	(	servo_config *	config,
		unsigned int	degree_of_rotation
	)

Set the angle of the servos attached to the servo port of SRA Board.

Parameters

config	pointer to the servo_config struct
degree_of_rotation	angle to which the servo must be set, depends on value of MAX_DEGREE macro

Returns

esp_err_t
