C programmer for Garmin FIT-SDK

We work with fitness data recorded in FIT file format. We need to decode this data regularly.
For this we use the C example of the FIT-SDK to read the FIT files directly via cython. The official C example must be extended for us now, so that also the developer data can be read in. It is sufficient to extend the C sample so that the developer data is displayed via Printf. The integration via cython will be done by us again.
For this we have a C prgoamm in Visual Code Run, which can display the normal data via printf and which we make available via gitlab.
