For the whose has an health or sport meter with the properties:

• can be connected with a (micro) usb that exposes a disk containing a data file.
• the file is a concatenation of measurements, until the meter's memory is full (and has to be erased from the device).
• the measurement binary files:
  • contains some data
  • contains records separated by a series of $ff (odd or even)
    • the header
    • the record number
    • some data
    • the date and time as plain char numbers (only from 0 to 12, 23, 31 or 59 are used)
    • some data
    • the sampling rate as the time, in seconds, between two samples.
    • some data
      • contains a data zone that can read as a raw file 8bits, signed, 2 channels
      • this data is between 0 and 100
  • terminates with a set of $ff
  • contains some data

This project is for him.

The project process:

• the parsing of the arguments to get the files names
  • if no file-name is provided at all, the default one is used
  • if at least one is provided, it or they are processed
• the reading of these binary files in the same order
• some statistics. They are sent to the standard output as:
  • the record number
  • some data in debug mode only
  • the date
  • the time
  • the record length in minutes
  • the min, max and average
  • many percent of the time the value is under a certain threshold
• a file-name based on the first record time-stamp for each input file.
• a raw file, of that file-name, intended to be open by most of the music editing software.
  • a record limit containing the time-stamp in the 2 channels. It has been design to not be confused with the record themselves
    • 100% sample
    • date
    • 0%
    • time
    • 100% sample The user has to zoom at the maximum to see the samples individually. The numbers (between 0 and 59) are coded as 2 samples. One is for the left digit, one for the right. They are multiplied by 10%. e.g. 52 is 50% 20%.
  • the data converted from 0 to 100% into 0 to 127. By this way, the editing software shows 100% for a 100% measure.

An additional feature applies if a record follows the previous one exactly one hour later:

• the statistics display the time only, not the date.
• the record limit, in the raw file, are omitted.

All the interfaces with the machine are done via the C++11 features. The project should compile by a simple "make" invocation. The Makefile supports the SOURCEDIR, BUILDDIR, DESTDIR, CXX, CXXFLAGS and LDFLAGS variables for cross-compilation.

It compiles on Ubuntu, Windows and MacOS-X There is a work-flow to build standard versions. For specific versions, such as default names, one has to build himself.

TODO or never: handle properly the new year and fix the bug that does not merge the records in the new year night.
