Input data of Acc and Gyro Modification

[mehtivakili]

Hi I'm using BMI088 IMU and also with help of Bolder flight library I'm taking the data from the sensor, and you can get either raw or real data.
I think when we're using acc and gyro data As the raw data as this project does it's important to mention the accelerometer range (2G, 3G, 10G, etc.) and Gyro range (250 dps, 500, 1000 and etc.) because when you change the range your data mapping would be different, and your scale would vary.
I wanted to know when I wanna use this calibration library I should map my data to this or I'm not right.
Another problem that I've been facing is the offset because my data from sensor doesn't have this offset so any help would be so much appreciated.
