Question

I have a bunch of binary files that contain data in the following format:

i\xffhh\xffhh\xffhh\xffih\xffhh\xffhh\xffhh\xffhh\xffhi\xffii\xffjj\xffjj\xffjj\xffjk\xffkk\xffkk\xffkl\xffll\xffmm\xffmn\xffnn\xffon\xffno\xffop\xffop\xffpp\xffqq\xffrq\xffrs\xffst\xfftt\xfftt\xffuv\xffvu\xffuv\xffvv\xffvw\xffwx\xffwx\xffxy\xffyy\xffyz\xffz{\xffz{\xff||\xff}|\xff~}\xff}}\xff~~\xff~~\xff~\x7f\xff\x7f\x7f\xff\x7f\x7f\xff\x7f\x7f\xff\x80\x80\xff\x80\x81\xff\x81\x80\xff\x81\x81\xff\x81\x82\xff\x82\x82\xff\x82\x82\xff\x82\x83\xff\x83\x83\xff\x83\x83\xff\x83\x84\xff\x83\x84\xff\x84\x85\xff\x85\x85\xff\x86\x85\xff\x86\x87\xff\x87\x87\xff\x87\x87\xff\x88\x87\xff\x88\x89\xff\x88\x89\xff\x89\x8a\xff\x89\x8a\xff\x8a\x8b\xff\x8b\x8b\xff\x8b\x8c\xff\x8d\x8d\xff\x8d\x8d\xff\x8e\x8e\xff\x8e\x8f\xff\x8f\x8f

These are supposed to be pressure sensor readings from when a person is walking, so I’m assuming that they are numbers, but I want to convert them into ascii so I have some idea what they are. How do I convert them? What format are they currently in?

Answer 1

You can not guess the format by just opening up a binary file. You will have to get the information on the way data is stored for that particular pressure sensor readings.

Of course, when you know the format, it is easy to read the file in binary mode and then get all the meaningful data from it

FILE = open(filename,"rb")
FILE.read(numBytes)
