Enumeration Type Documentation

anonymous enum

anonymous enum

The SX150x led driver calc status codes.

Enumerator
SX150x_LED_DRC_CALC_STATUS_CODE_SUCCESS	Successful.
SX150x_LED_DRV_CALC_STATUS_CODE_INACCURATE	One or more of the set time parameters deviate by more than 20 %. Accept or try again with different values or osc divider.
SX150x_LED_DRV_CALC_STATUS_CODE_INVALID_PARAM	Invalid parameters.
SX150x_LED_DRV_CALC_STATUS_CODE_NULL	NULL parameter supplied.
SX150x_LED_DRV_CALC_STATUS_CODE_NOT_INIT	The module has not been initalized. Has init been called?

Function Documentation

sx150x_led_drv_calc_convert()

ret_code_t sx150x_led_drv_calc_convert	(	uint16_t	port_mask,
		drv_ext_light_sequence_t *const	real_vals,
		sx150x_led_drv_regs_vals_t *const	reg_vals
	)

Converts from real values (intensity (0x00-0xFF and time in milliseconds) to register values.

Parameters

[in]	port_mask	16-bit port mask
[in,out]	real_vals	The requested values. Will contain the actual set values after processing
[out]	reg_vals	Register values set as close as possible to achieve the requested values

Returns

SX150x_LED_DRC_CALC_STATUS_CODE_SUCCESS

SX150x_LED_DRV_CALC_STATUS_CODE_INACCURATE

SX150x_LED_DRV_CALC_STATUS_CODE_INVALID_PARAM

SX150x_LED_DRV_CALC_STATUS_CODE_NULL

SX150x_LED_DRV_CALC_STATUS_CODE_NOT_INIT

sx150x_led_drv_calc_fade_supp()

bool sx150x_led_drv_calc_fade_supp

(

uint16_t

port_mask

)

Checks if all the supplied pins in port_mask supports fade.

Parameters

[in]

port_mask

16-bit port mask.

Note

: If port_mask = 0, false is returned.

Returns

true All the given pins support fade.

false One or more of the supplied pins does not support fade.

sx150x_led_drv_calc_init()

void sx150x_led_drv_calc_init	(	uint16_t	fade_supported_port_mask,
		uint32_t	clkx_tics_pr_sec
	)

Initializes the SX150x led driver register calculation module.

Parameters

[in]	fade_supported_port_mask	16-bit port mask holding "1" in positions corresponding to pins which supports fading.
[in]	clkx_tics_pr_sec	Number of ticks / sec for the internal ioext oscillatior after division.
