Read / Write data to the given register address.

Collaboration diagram for Registers:

Read / Write data to the given register address.

bmp3_set_regs

int8_t bmp3_set_regs(uint8_t *reg_addr, const uint8_t *reg_data, uint8_t len, const struct bmp3_dev *dev);

This API writes the given data to the register address of the sensor.

Parameters

[in]	reg_addr	: Register address to where the data to be written.
[in]	reg_data	: Pointer to data buffer which is to be written in the sensor.
[in]	len	: No. of bytes of data to write.
[in]	dev	: Structure instance of bmp3_dev.

Returns

Result of API execution status

Return values

0	-> Success
>0	-> Warning
<0	-> Error

bmp3_get_regs

int8_t bmp3_get_regs(uint8_t reg_addr, uint8_t *reg_data, uint16_t length, const struct bmp3_dev *dev);

This API reads the data from the given register address of the sensor.

Parameters

[in]	reg_addr	: Register address from where the data to be read
[out]	reg_data	: Pointer to data buffer to store the read data.
[in]	len	: No. of bytes of data to be read.
[in]	dev	: Structure instance of bmp3_dev.

Returns

Result of API execution status

Return values

0	-> Success
>0	-> Warning
