Function Documentation

phydat_to_senml_bool()

void phydat_to_senml_bool	(	senml_bool_value_t *	senml,
		const phydat_t *	phydat,
		const uint8_t	dim )

Create a SenML boolean value.

Writes the value of the given dim of phydat as a boolean. phydat is assumed to be of UNIT_BOOL.

Note

phydat->scale must be zero.

Parameters

[out]	senml	SenML value to store value in.
[in]	phydat	Phydat to convert.
[in]	dim	Dimension of phydat to convert.

phydat_to_senml_decimal()

void phydat_to_senml_decimal	(	senml_value_t *	senml,
		const phydat_t *	phydat,
		const uint8_t	dim )

Create a SenML decimal fraction value.

Writes the value of the given dim of phydat as a decimal value. The unit of phydat is converted using the following rules:

• UNIT_TIME is converted to SENML_UNIT_SECOND.
• UNIT_BAR is converted to SENML_UNIT_PASCAL.
• UNIT_GPM3 is converted to SENML_UNIT_KILOGRAM_PER_CUBIC_METER.
• UNIT_GAUSS is converted to SENML_UNIT_TESLA.
• Compatible units are set to their SenML equivalent.
• Incompatible (or unknown) units are set to SENML_UNIT_NONE.

Parameters

[out]	senml	SenML value to store value in.
[in]	phydat	Phydat to convert.
[in]	dim	Dimension of phydat to convert.

phydat_to_senml_float()

void phydat_to_senml_float	(	senml_value_t *	senml,
		const phydat_t *	phydat,
		const uint8_t	dim )

Create a SenML float value.

Writes the value of the given dim of phydat as a float. The unit of phydat is converted using the following rules:

• UNIT_TIME is converted to SENML_UNIT_SECOND.
• UNIT_F is converted to SENML_UNIT_KELVIN.
• UNIT_G_FORCE is converted to SENML_UNIT_METER_PER_SQUARE_SECOND.
• UNIT_BAR is converted to SENML_UNIT_PASCAL.
• UNIT_GPM3 is converted to SENML_UNIT_KILOGRAM_PER_CUBIC_METER.
• UNIT_GAUSS is converted to SENML_UNIT_TESLA.
• Compatible units are set to their SenML equivalent.
• Incompatible (or unknown) units are set to SENML_UNIT_NONE.

Parameters

[out]	senml	SenML value to store value in.
[in]	phydat	Phydat to convert.
[in]	dim	Dimension of phydat to convert.
