# BME680 sensor API
|
||||
|
||||
## Introduction
|
||||
|
||||
This package contains the Bosch Sensortec's BME680 gas sensor API
|
||||
|
||||
The sensor driver package includes bme680.h, bme680.c and bme680_defs.h files
|
||||
|
||||
## Version
|
||||
|
||||
File | Version | Date
|
||||
--------------|---------|-------------
|
||||
bme680.c | 3.5.8 | 22 Feb 2018
|
||||
bme680.h | 3.5.8 | 22 Feb 2018
|
||||
bme680_defs.h | 3.5.8 | 22 Feb 2018
|
||||
|
||||
## Integration details
|
||||
|
||||
* Integrate bme680.h, bme680_defs.h and bme680.c file in to your project.
|
||||
* Include the bme680.h file in your code like below.
|
||||
|
||||
``` c
|
||||
#include "bme680.h"
|
||||
```
|
||||
|
||||
## File information
|
||||
|
||||
* bme680_defs.h : This header file has the constants, macros and datatype declarations.
|
||||
* bme680.h : This header file contains the declarations of the sensor driver APIs.
|
||||
* bme680.c : This source file contains the definitions of the sensor driver APIs.
|
||||
|
||||
## Supported sensor interfaces
|
||||
|
||||
* SPI 4-wire
|
||||
* I2C
|
||||
|
||||
## Usage guide
|
||||
|
||||
### Initializing the sensor
|
||||
|
||||
To initialize the sensor, you will first need to create a device structure. You
|
||||
can do this by creating an instance of the structure bme680_dev. Then go on to
|
||||
fill in the various parameters as shown below
|
||||
|
||||
#### Example for SPI 4-Wire
|
||||
|
||||
``` c
|
||||
struct bme680_dev gas_sensor;
|
||||
|
||||
/* You may assign a chip select identifier to be handled later */
|
||||
gas_sensor.dev_id = 0;
|
||||
gas_sensor.intf = BME680_SPI_INTF;
|
||||
gas_sensor.read = user_spi_read;
|
||||
gas_sensor.write = user_spi_write;
|
||||
gas_sensor.delay_ms = user_delay_ms;
|
||||
/* amb_temp can be set to 25 prior to configuring the gas sensor
|
||||
* or by performing a few temperature readings without operating the gas sensor.
|
||||
*/
|
||||
gas_sensor.amb_temp = 25;
|
||||
|
||||
int8_t rslt = BME680_OK;
|
||||
rslt = bme680_init(&gas_sensor);
|
||||
```
|
||||
|
||||
#### Example for I2C
|
||||
|
||||
``` c
|
||||
struct bme680_dev gas_sensor;
|
||||
|
||||
gas_sensor.dev_id = BME680_I2C_ADDR_PRIMARY;
|
||||
gas_sensor.intf = BME680_I2C_INTF;
|
||||
gas_sensor.read = user_i2c_read;
|
||||
gas_sensor.write = user_i2c_write;
|
||||
gas_sensor.delay_ms = user_delay_ms;
|
||||
/* amb_temp can be set to 25 prior to configuring the gas sensor
|
||||
* or by performing a few temperature readings without operating the gas sensor.
|
||||
*/
|
||||
gas_sensor.amb_temp = 25;
|
||||
|
||||
|
||||
int8_t rslt = BME680_OK;
|
||||
rslt = bme680_init(&gas_sensor);
|
||||
```
|
||||
|
||||
Regarding compensation functions for temperature, pressure, humidity and gas we have two implementations.
|
||||
|
||||
- Integer version
|
||||
- floating point version
|
||||
|
||||
By default, Integer version is used in the API
|
||||
|
||||
If the user needs the floating point version, the user has to un-comment BME680_FLOAT_POINT_COMPENSATION macro
|
||||
in bme680_defs.h file or to add it in the compiler flags.
|
||||
|
||||
### Configuring the sensor
|
||||
|
||||
#### Example for configuring the sensor in forced mode
|
||||
|
||||
``` c
|
||||
uint8_t set_required_settings;
|
||||
|
||||
/* Set the temperature, pressure and humidity settings */
|
||||
gas_sensor.tph_sett.os_hum = BME680_OS_2X;
|
||||
gas_sensor.tph_sett.os_pres = BME680_OS_4X;
|
||||
gas_sensor.tph_sett.os_temp = BME680_OS_8X;
|
||||
gas_sensor.tph_sett.filter = BME680_FILTER_SIZE_3;
|
||||
|
||||
/* Set the remaining gas sensor settings and link the heating profile */
|
||||
gas_sensor.gas_sett.run_gas = BME680_ENABLE_GAS_MEAS;
|
||||
/* Create a ramp heat waveform in 3 steps */
|
||||
gas_sensor.gas_sett.heatr_temp = 320; /* degree Celsius */
|
||||
gas_sensor.gas_sett.heatr_dur = 150; /* milliseconds */
|
||||
|
||||
/* Select the power mode */
|
||||
/* Must be set before writing the sensor configuration */
|
||||
gas_sensor.power_mode = BME680_FORCED_MODE;
|
||||
|
||||
/* Set the required sensor settings needed */
|
||||
set_required_settings = BME680_OST_SEL | BME680_OSP_SEL | BME680_OSH_SEL | BME680_FILTER_SEL
|
||||
| BME680_GAS_SENSOR_SEL;
|
||||
|
||||
/* Set the desired sensor configuration */
|
||||
rslt = bme680_set_sensor_settings(set_required_settings,&gas_sensor);
|
||||
|
||||
/* Set the power mode */
|
||||
rslt = bme680_set_sensor_mode(&gas_sensor);
|
||||
|
||||
|
||||
```
|
||||
|
||||
### Reading sensor data
|
||||
|
||||
#### Example for reading all sensor data
|
||||
|
||||
``` c
|
||||
/* Get the total measurement duration so as to sleep or wait till the
|
||||
* measurement is complete */
|
||||
uint16_t meas_period;
|
||||
bme680_get_profile_dur(&meas_period, &gas_sensor);
|
||||
|
||||
struct bme680_field_data data;
|
||||
|
||||
while(1)
|
||||
{
|
||||
user_delay_ms(meas_period); /* Delay till the measurement is ready */
|
||||
|
||||
rslt = bme680_get_sensor_data(&data, &gas_sensor);
|
||||
|
||||
printf("T: %.2f degC, P: %.2f hPa, H %.2f %%rH ", data.temperature / 100.0f,
|
||||
data.pressure / 100.0f, data.humidity / 1000.0f );
|
||||
/* Avoid using measurements from an unstable heating setup */
|
||||
if(data.status & BME680_GASM_VALID_MSK)
|
||||
printf(", G: %d ohms", data.gas_resistance);
|
||||
|
||||
printf("\r\n");
|
||||
|
||||
/* Trigger the next measurement if you would like to read data out continuously */
|
||||
if (gas_sensor.power_mode == BME680_FORCED_MODE) {
|
||||
rslt = bme680_set_sensor_mode(&gas_sensor);
|
||||
}
|

}

```
|

can do this by creating an instance of the structure bme680_dev. Then go on to
|

fill in the various parameters as shown below
