Function Documentation

VL53L1_calc_pll_period_us()

uint32_t VL53L1_calc_pll_period_us

(

uint16_t

fast_osc_frequency

)

Calculates the PLL period in [us] from the input fast_osc_frequency.

Parameters

[in]

fast_osc_frequency

: fast oscillator frequency in 4.12 MHz format

Returns

pll_period_us : PLL period in [us] 8.24 format

Definition at line 94 of file vl53l1_core_support.c.

VL53L1_decode_row_col()

void VL53L1_decode_row_col	(	uint8_t	spad_number,
		uint8_t *	prow,
		uint8_t *	pcol
	)

Decodes the Byte.Bit coord encoding into an (x,y) coord value.

Parameters

[in]	spad_number	: Coord location in Byte.Bit format
[out]	prow	: Decoded row
[out]	pcol	: Decoded column

Decodes the array (row,col) location from the input SPAD number

Definition at line 426 of file vl53l1_core_support.c.

VL53L1_decode_vcsel_period()

uint8_t VL53L1_decode_vcsel_period

(

uint8_t

vcsel_period_reg

)

Decodes VCSEL period register value into the real period in PLL clocks.

Parameters

[in]

vcsel_period_reg

: 8 -bit register value

Returns

vcsel_period_pclks : 8-bit decoded value
