Member Function Documentation

begin()

bool GP2Y0A21_Sensor::begin	(	uint8_t	pin_num,
		uint8_t	mode = INPUT_PULLDOWN
	)

Initialize the distance sensor class.

Parameters

[in]	pin_num	on Launchpad connected to distance sensor's analog output.
[in]	mode	for input pin. Options are the same as standard Energia/Arduino pin mode.

This function needs to be called before any other function is used.

read()

uint16_t GP2Y0A21_Sensor::read

(

)

Read the value from distance sensor.

Returns

Return a value of 0 - 4095. The lower the value the closer an object is.

This function returns a value representing the distance an object is from the sensor.
