Functions
Servo public funtions
int	servo_position (uint16_t gptab, uint8_t port, uint8_t pin, uint16_t pos)
	Configures and positions a servo in a given position (by degrees) The servo will lock its position as long as it is not stopped. More...
int	servo_stop (uint16_t gptab, uint8_t port, uint8_t pin)
	Fully stop a servo and reconfigures back the pin/port as GPIO. More...
