@BSTRobin, @FAE_CA1 Can one of you please tell me if what I'm trying to do is possible? Cheers Bonny ... View more

Hi @BSTRobin Any help possible here? ... View more

Hi @BSTRobin, Thanks for your reply.  However I think there's still a misunderstanding about what I am trying to do so I'll try again. I've written a piece of software that communicates over SPI with Arduino where the Bosch Sensortec library is used to read sensor data. The arduino side of things reads the calibration data (as recommended in the documentation), sets the sensor mode to normal and starts reading sensor data. Since the data is used on the arduino side feed into the compensation methods of the BStec libraries I wanted to know what data I can provide in the calibration data such that when the sensor data is read and the software is reporting something like 0x789AB (20 bits in 16.4 format) the resulting value would be something that represents the top of the range of the temperature sensor, resulting in something like 75.12 *C. To be clear I am not trying to reimplement the hardware, rather allow users to add this component to a simulator like Tinkercad for whatever project they are building. I hope this helps clarify my query.   Cheers,   Bonny     ... View more

@BSTRobin  - I'm wondering whether what I'm after is possible?   Cheers,   Bonny ... View more

Hi BSTRobin, I think I did not make myself clear on what I am trying to do - I am trying to produce values that a typical sensor would in software. In other words, I am simulating the sensor. So I need to find out how to compose the raw values, so that when some code (running on arduino) reads temperature for example, and they use the Bosch libraries you're citing, they will get reasonable values from the raw values the simulation generates. I tried to understand what each of the coefficients does so that I can compute the raw values (t,p,h) from measurements, (for example what  raw value I should have for a temperature of 25 deg c) but failed 🙂  So, I am asking for a way for me to simply, map the range of temperatures to an ADC values (for temp, use 20bits for the ~125 deg possible) and have a default coefficient map that would be like an identity operation map ( multiply or divide by 1, add or subtract 0, etc) I hope this is possible ...
