How to count bits and specify the correct format?

Hello everyone, I’m currently working on a car dashboard, so everything is going well, I would like to clarify how I can calculate the output data, for example high beam, in targetid I ​​found 157, the package that is responsible for this is like this: 0x21a: 05 12 f7 00 00 00 00 00, what should it look like in the XML file?

In order to help, provide data what you have on frame 0x21a when:

  • high beam is off.
  • high beam is on.
