i have a sensor

The datasheet says you can divide the data from the sensor by 100 to get the data you want. And for example, 0xff97 is -1.05km/h

How does 0xff97 become -1.05 km/h?

CodePudding user response：

0xFF97 is -105 in 16-bit two's complement integer representation.

If you divide that number by 100, then you get -1.05 km/h.
