How to convert data from binary format?

Question

Microcontrollers

I connect to the device through the terminal 1.9b program, with the specified manufacturer's settings.
The terminal program catches incorrect data. The instructions say

The instrument sends a data packet in binary format at the end of each measurement.

Tell me how to get the data in a normal format

Answer 1

Binary data is normal data. You just need to read them correctly. Only the instructions will help you read them correctly. Or try to guess the data structure manually.
To do this, you need to read part of the data into byte, int, int64, float and other variables of various sizes.

Answer 2

Describe the data structure in Protobuf according to the instructions and generate code in Ce++.
