◆ SerialWombatUltrasonicDistanceSensor()

SerialWombatUltrasonicDistanceSensor::SerialWombatUltrasonicDistanceSensor ( SerialWombatChip & serialWombat )

inline

Class constructor for SerialWombatPulseTimer.

Parameters

serialWombat The Serial Wombat chip on which the SerialWombatPulseTimer pinmode will be run

Member Function Documentation

◆ begin()

int16_t SerialWombatUltrasonicDistanceSensor::begin	(	uint8_t	echoPin,
		driver	driver,
		uint8_t	triggerPin,
		bool	autoTrigger = true,
		bool	pullUp = false )

inline

Initialization routine for SerialWombatUltrasonicDistanceSensor.

Parameters

echoPin	Pin used to time input pulses. For 5V sensors, 5V tolerant pins 9,10,11,12, 14 and 15 are good choices
driver	Chip used for distance measurement. Currently only HC_SR04 is supported.
triggerPin	Pin used for triggering the sensor. If same as echo pin (e.g. 3 pin sensors) set equal to echoPin

Returns: 0 or higher if successful, negative error code if not successful.
