The list below describes some of the tools you can use to work with the .hdf files created by ICOc.
- HDFView: Tool to open and view HDF files. For more information on how to work with the files created by ICO in HDFView please take a look at the documentation of ICOc.
h5dump: CLI tool to view HDF5 data; Part of HDF5 library download
- ICOlyzer: Tools to analyze measurement data from the ICOtronic system
The embedded devices of the ICOtronic system (STH, STU, SMH) only have knowledge of relative time, i.e. they can tell you about the time difference between two timepoints, but they do not know “which time it is”. They simply do not have access to a time source for absolute time, such as a time server or an atomic clock.
In the case of ICOc the measurement computer adds the information about the absolute time a measurement takes place. This means that the timestamps in the measurement files are dependent on the time settings of the computer. Since the timing information is taken from the timestamp of a CAN message multiple data points have the same timestamp. The 8 data bytes of a CAN streaming data message will contain three 16 bit measurement values, which all share the same timestamp.
