Function Documentation

setupEncoder()

void setupEncoder	(	uint8_t	ela_pin,
		uint8_t	elb_pin,
		uint8_t	era_pin,
		uint8_t	erb_pin
	)

Initialize the wheel encoder.

Parameters

[in]	ela_pin	pin number on Launchpad connected to ELA pin on encoder.
[in]	elb_pin	pin number on Launchpad connected to ELB pin on encoder.
[in]	era_pin	pin number on Launchpad connected to ERA pin on encoder.
[in]	erb_pin	pin number on Launchpad connected to ERB pin on encoder.

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