laps

plb_qei_encoder_get_phase_count()

uint32_t plb_qei_encoder_get_phase_count	(	PLB_Type *	plb,
		plb_qei_encoder_channel_t	qei_chn
	)

Get location information.

Parameters

plb	PLB_Type
qei_chn	plb_qei_encoder_channel_t

plb_qei_encoder_init()

hpm_stat_t plb_qei_encoder_init	(	PLB_Type *	plb,
		TRGM_Type *	trgm,
		plb_qei_encoder_channel_t	qei_chn,
		plb_qei_encoder_cfg_t *	cfg
	)

Initializing the encoder.

Parameters

plb	PLB_Type
trgm	TRGM_Type

cfg	plb_qei_encoder_cfg_t

Returns

hpm_stat_t Whether the initialization is successful or not

pwm

pulse

z phase

Wait for the circuit to stabilize

Zeroing registers, because of the timing logic, requires multiple zeroes to completely erase the data

	)

Set Lap data.

Parameters

plb	PLB_Type
qei_chn	plb_qei_encoder_channel_t
val	laps

plb_qei_encoder_set_phase_count()

void plb_qei_encoder_set_phase_count	(	PLB_Type *	plb,
