BME680 latest sensor API implementation for reference relation between amb_temp & bme680_field_data?

[Mich]

Hello,

For the "BME680 latest sensor API implementation for reference" what is the relationship between : bme680_field_data.temperature and bme680_dev.amb_temp please?

/100?

bme680_field_data->temperature = calc_temperature(adc_temp, dev);

but nothing how to set bme680_dev.amb_temp ????

Best regards

Mich

bme680_dev.amb_temp is an input for the gas sensor configuration. It is possible to keep a hard-coded, for example at 25.

bme680_field_data.temperature is the output of BME680's temperature sensor measurement. To support some decimal points, the resolution of the integer formula output is 100LSB/°C, while the floating-point formula outputs directly in °C. It is recommend to use the floating-point implementation if your platform supports it.
