Function Documentation

int32_t xensiv_pasco2_get_reg(const xensiv_pasco2_t *dev, uint8_t reg_addr, uint8_t *data, uint8_t len)

Reads from the sensor device into the given data buffer. Reads from the sensor register map sensor starting at register address into the given data buffer.

Parameters

  • dev – [in] Pointer to the XENSIV™ PAS CO2 sensor device

  • reg_addr – [in] Start register address

  • data – [out] Pointer to the data buffer to store the register values of the sensor

  • len – [in] Number of bytes of data to be read

Returns

XENSIV_PASCO2_OK if reading from the register was successful; an error indicating what went wrong otherwise
