Functions for using SPI bus.

Function Documentation

ri_spi_bme280_read()

int8_t ri_spi_bme280_read	(	uint8_t	dev_id,
		uint8_t	reg_addr,
		uint8_t *	p_reg_data,
		uint16_t	len
	)

SPI Read function for BME280.

Binds Ruuvi Interface SPI functions into official Bosch BME280 driver. Handles GPIO chip select, there is no forced delay to let th CS settle.

Parameters

[in]	dev_id	SPI functions interface handle, i.e. pin number of the chip select pin of BME280.
[in]	reg_addr	BME280 register address to read.
[in]	p_reg_data	pointer to data to be received.
[in]	len	length of data to be received.

ri_spi_bme280_write()

int8_t ri_spi_bme280_write	(	uint8_t	dev_id,
		uint8_t	reg_addr,
		uint8_t *	p_reg_data,
		uint16_t	len
	)

SPI write function for BME280.

Binds Ruuvi Interface SPI functions into official Bosch BME280 driver. Handles GPIO chip select, there is no forced delay to let th CS settle.

Parameters

[in]	dev_id	SPI functions interface handle, i.e. pin number of the chip select pin of BME280.
[in]	reg_addr	BME280 register address to write.
[in]	p_reg_data	pointer to data to be written.
[in]	len	length of data to be written.

ri_spi_dps310_read()

uint32_t ri_spi_dps310_read	(	const void *const	comm_ctx,
		const uint8_t	reg_addr,
		uint8_t *const	p_reg_data,
		const uint8_t	data_len
	)

SPI Read function for DPS310.

Binds Ruuvi Interface SPI functions into Ruuvi DPS310 driver. Handles GPIO chip select, there is no forced delay to let the CS settle.

Parameters

[in]	comm_ctx	SPI functions interface handle, i.e. pin number of the chip select pin of DPS310.
[in]	reg_addr	DPS310 register address to read.
[in]	p_reg_data	pointer to data to be received.
[in]	data_len	length of data to be received.

Return values

0	on Success.

Returns

Error code from SPI implementation on error.

ri_spi_dps310_write()

uint32_t ri_spi_dps310_write	(	const void *const	comm_ctx,
		const uint8_t	reg_addr,
		const uint8_t *const	p_reg_data,
		const uint8_t	data_len
	)

SPI write function for DPS310.

Binds Ruuvi Interface SPI functions into Ruuvi's DPS310 driver. Handles GPIO chip select, there is no forced delay to let the CS settle.

Parameters

[in]	reg_addr	DPS310 register address to write.
[in]	p_reg_data	pointer to data to be written.
[in]	data_len	length of data to be written.

Return values

0	on Success.

Returns

Error code from SPI implementation on error.
