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);` ? ...

If anyone has test raw data for the BME280 and is willing to share, I would be most grateful   ... View more

Hi @BSTRobin    I am not sure why we are going in circles... I am trying to produce these raw values so that a user software, using the BST library can read these over SPI and coupled with the coefficients, get the compensated values So for example, what should I put in the 24bit of the temperature registers so that when a client reads that they can convert to a real temperature?   So if I wanted to generate the raw values for: Temperature. Register Values (FA, FB, FC) 20*C ? ? ? 25*C ? ? ? -15*C ? ? ? -2.5C ? ? ? I know you'd say these depend on the coefficients, but given a set of coefficients what are the register values for the above temperatures? Alternatively, is there a way to program the coefficients for test purposes so that they simply are ignored (identity)? for example, if I used 0x1000 with those coefficients, the resulting temperature would be 40.96*C? ...

Hi @BSTRobin    As you know (from my other thread)  I am aware of these functions. Since I did not get a response regarding the question I asked there, I am asking for test data from community members (understanding these would be for a particular sensor) Since any BME280 user using the Bosch library would read the coefficients first before computing the compensated values using  your library, providing this test data should produce the same readings for other users. Under normal circumstances, this is not necessary since users are building projects using the actual hardware, but as I mentioned in the previous post, I am doing this to support a community of users using arduino simulator environment like Tinkercad. Hope this makes sense?     ... View more
