BMP581 Calibration

[mgchoi]

Hi, BOSCH

There is no calibration in the data sheet of BMP581, so I checked and found that there is no need for calibration,
I found out that it was merged into Asic.

Then, I understand that there is no need to set with Driver like BMP390, but does it automatically correct?

What is the difference from the System of BMP390?

Hi Mgchoi, 

What Robin wanted to say is BMP581 is delievered in a completely calibrated form. However, as you said, the manufacuring process generates additional offset. That's why you need EOL calibration at the end. 

After calibration done, you can store it in 0x20 ~ 0x22. 

You can refer to our datasheet. 4.8. NVM as well. 

Thank you.

Thank you for the brief explanation!
It's not that different from BMP390
