Function Documentation

◆ color13_cfg_setup()

void color13_cfg_setup ( color13_cfg_t * cfg )

Color 13 configuration object setup function.

This function initializes click configuration structure to initial values.

Parameters

[out] cfg : Click configuration structure. See color13_cfg_t object definition for detailed explanation.

Returns: Nothing.

Note: The all used pins will be set to unconnected state.

◆ color13_generic_read()

err_t color13_generic_read	(	color13_t *	ctx,
		uint8_t	reg,
		uint8_t *	rx_buf,
		uint8_t	rx_len )

Color 13 I2C reading function.

This function reads a desired number of data bytes starting from the selected register by using I2C serial interface.

Parameters

[in]	ctx	: Click context object. See color13_t object definition for detailed explanation.
[in]	reg	: Start register address.
[out]	rx_buf	: Output read data.
[in]	rx_len	: Number of bytes to be read.

Returns

0 - Success,
-1 - Error.

See #err_t definition for detailed explanation.

◆ color13_generic_write()

err_t color13_generic_write	(	color13_t *	ctx,
		uint8_t	reg,
		uint8_t *	tx_buf,
		uint8_t	tx_len )

Color 13 I2C writing function.

This function writes a desired number of data bytes starting from the selected register by using I2C serial interface.

Parameters

[in]	ctx	: Click context object. See color13_t object definition for detailed explanation.
[in]	reg	: Start register address.
[in]	tx_buf	: Data to be written.
[in]	tx_len	: Number of bytes to be written.

Returns

0 - Success,
-1 - Error.

See #err_t definition for detailed explanation.

◆ color13_get_als()

err_t color13_get_als	(	color13_t *	ctx,
		float *	als_data )

Read lux data from device.

This function reads adc data and calculates lux data from device.

Parameters

[in]	ctx	: Click context object. See color13_t object definition for detailed explanation.
[out]	als_data	: Output read data.

Returns

0 - Success,
-1 - Error.

See #err_t definition for detailed explanation.

Note: The device should be configured for ALS reading before calling this function. Bit RGB_MODE should be 0 and LS_EN should be 1, of the MAIN_CTRL register. The function will call function color13_get_als_resolution on it's first iteration for calculating lux data for its configuration. If you change the configuration of the device After calling this function once you need to call color13_get_als_resolution separately to set lux_resolution in the context object for getting current calculation of lux data.

◆ color13_get_als_resolution()

float color13_get_als_resolution ( color13_t * ctx )

Get resolution for the lux calculation.

Function reads configuration from device and returns corresponding lux resolution, and sets member lux_resolution of context object.

Parameters

[in,out]	ctx	: Click context object. See color13_t object definition for detailed explanation.
[out]	ps_data	: Output read data.

Returns: Resolution for the current configuration of als data.

◆ color13_get_int()

uint8_t color13_get_int ( color13_t * ctx )

Get interrupt pin state.

Read int_pin state.

Parameters

[in] ctx : Click context object. See color13_t object definition for detailed explanation.

Returns: Interrupt state.

◆ color13_get_proximity()

err_t color13_get_proximity	(	color13_t *	ctx,
		uint16_t *	ps_data )

Read proximity data from device.

This function reads a desired number of data bytes starting from the selected register by using I2C serial interface.

Parameters

[in]	ctx	: Click context object. See color13_t object definition for detailed explanation.
[out]	ps_data	: Output read data.

Returns

0 - Success,
-1 - Error,
-2 - Overflow,
-4 - Error configuration.

See #err_t definition for detailed explanation.

Note: Device should be configured for proximity reading before calling this function. Bit PS_EN should be 1, of the MAIN_CTRL register.

◆ color13_get_rgb_ir()

err_t color13_get_rgb_ir	(	color13_t *	ctx,
		color13_color_t *	color_data )

Read color data from device.

This function reads red, green, blue, and ir registers data and sets data in color_data object.

Parameters

[in]	ctx	: Click context object. See color13_t object definition for detailed explanation.
[out]	color_data	: Color data object. See color13_color_t object definition for detailed explanation.

Returns

0 - Success,
-1 - Error.

See #err_t definition for detailed explanation.

Note: The device should be configured for RGB reading before calling this function. Bits RGB_MODE and LS_EN, of the MAIN_CTRL register, should be set to 1.

◆ color13_init()

err_t color13_init	(	color13_t *	ctx,
		color13_cfg_t *	cfg )

Color 13 initialization function.

This function initializes all necessary pins and peripherals used for this click board.

Parameters

[out]	ctx	: Click context object. See color13_t object definition for detailed explanation.
[in]	cfg	: Click configuration structure. See color13_cfg_t object definition for detailed explanation.

Returns

0 - Success,
-1 - Error.

See #err_t definition for detailed explanation.

◆ color13_ls_color()

err_t color13_ls_color	(	color13_t *	ctx,
		uint8_t	ls_reg,
		uint32_t *	ls_data )

Read ls data from color registers.

This function reads data from reg, green, blue or ir registers and returns data to ls_data.

Parameters

[in]	ctx	: Click context object. See color13_t object definition for detailed explanation.
[in]	ls_reg	: LSB register address of data.
[out]	ls_data	: Output read data.

Returns

0 - Success,
-1 - Error,
-3 - Error Parameter.

See #err_t definition for detailed explanation.

Note: The device should be configured to enable LS reading before calling this function. You can configure it by setting LS_EN bit of the MAIN_CTRL register. Depending of the reading you want to use you can configure RGB_MODE bit to 0 if you want ALS data from COLOR13_REG_LS_DATA_GREEN_0 register or to 1 if you want RGB data from LS registers.
