Function Documentation

loadcell7_calibrate_weight()

err_t loadcell7_calibrate_weight	(	loadcell7_t *	ctx,
		float	cal_weight )

Load Cell 7 calibrate weight function.

This function calibrates the weight by calculating the ctx->weight_scale for the input calibration weight.

Parameters

[in]	ctx	: Click context object. See loadcell7_t object definition for detailed explanation.
[in]	cal_weight	: Calibration weight value in grams of the goods placed on the scale.

Returns

• 0 - Success,
• -1 - Error. See #err_t definition for detailed explanation.

Note

None.

loadcell7_cfg_setup()

void loadcell7_cfg_setup

(

loadcell7_cfg_t *

cfg

)

Load Cell 7 configuration object setup function.

This function initializes click configuration structure to initial values.

Parameters

[out]

cfg

: Click configuration structure. See loadcell7_cfg_t object definition for detailed explanation.

Returns

Nothing.

Note

The all used pins will be set to unconnected state.

loadcell7_disable_device()

void loadcell7_disable_device

(

loadcell7_t *

ctx

)

Load Cell 7 disable device function.

This function disables the device by setting the CS (PWDN) pin to low logic state.

Parameters

[in]

ctx

: Click context object. See loadcell7_t object definition for detailed explanation.

Returns

None.

Note

None.

loadcell7_enable_device()

void loadcell7_enable_device

(

loadcell7_t *

ctx

)

Load Cell 7 enable device function.

This function enables the device by setting the CS (PWDN) pin to high logic state.

Parameters

[in]

ctx

: Click context object. See loadcell7_t object definition for detailed explanation.

Returns

None.

Note

None.

loadcell7_get_weight()

err_t loadcell7_get_weight	(	loadcell7_t *	ctx,
		float *	weight )

Load Cell 7 get weight function.

This function calculates the weight of the goods in grams.

Parameters

[in]	ctx	: Click context object. See loadcell7_t object definition for detailed explanation.
[out]	weight	: The weight of the goods in grams.

Returns

• 0 - Success,
• -1 - Error. See #err_t definition for detailed explanation.

Note

This function relies on the loadcell7_tare_scale and loadcell7_calibrate_weight functions calculation results.

loadcell7_init()

err_t loadcell7_init	(	loadcell7_t *	ctx,
		loadcell7_cfg_t *	cfg )

Load Cell 7 initialization function.

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

Parameters

[out]	ctx	: Click context object. See loadcell7_t object definition for detailed explanation.
[in]	cfg	: Click configuration structure. See loadcell7_cfg_t object definition for detailed explanation.

Returns

• 0 - Success,
• -1 - Error. See #err_t definition for detailed explanation.

Note

None.

loadcell7_read_raw_adc()

err_t loadcell7_read_raw_adc	(	loadcell7_t *	ctx,
		int32_t *	data_out )

This function reads raw ADC measurements using SPI serial interface.

Parameters

[in]	ctx	: Click context object. See loadcell7_t object definition for detailed explanation.
[out]	data_out	: 24-bit ADC data out.

Returns

• 0 - Success,
• -1 - Error. See #err_t definition for detailed explanation.

Note

None.

loadcell7_tare_scale()

err_t loadcell7_tare_scale

(

loadcell7_t *

ctx

)

This function calculates the ctx->tare_scale which is the raw ADC readings of the empty container.

Parameters

[in]

ctx

: Click context object. See loadcell7_t object definition for detailed explanation.

Returns

• 0 - Success,
• -1 - Error. See #err_t definition for detailed explanation.

Note

None.
