Are there a default, identity values for the calibration data of the BME280

[bonnyr]

Hi there,

I am in the process of creating a software version of the BME280 and one thing I cannot find is how to 
program the calibration data such that I can simply use raw values that would be equal to the compensated values

For example if I have a raw temperature (16.4 format) with the value 0x3FFF0 then have a value that reads something like 84.99 celsius 

Alternatively, is there a way to invert the formulas such that if I start with a temperature I can compute the raw value?

Hi @BSTRobin 

I am still looking for answers 🙂 

Is this possible to accomplish what I am attempting?

To clarify again - given a set of coefficients, is there  a way to compute the values of the temperature registers (raw data) from a given temperature, something like `uint32_t BST_calculate_raw_temp(float temp);` ?

Hi bonnyr,

As described in BME280 data sheet, sensor provide  temperature, humidity, pressure value output. The coefficient register is related to the chip design. We have no plan to open its details.
