Update to new waterfall file format #22

Closed wose closed 4 years ago

wose commented 4 years ago

As pointed out by @arope99 the waterfall format changed:

I'm using satnogs-client 1.1.2 and gr-satnogs 2.0.1-1 on armhf erpi4. The frequencies information are not on the first bytes of the waterfall files.

You can see the format as shown in the following codes taken from https://gitlab.com/librespacefoundation/satnogs/gr-satnogs/-/blob/v2.0.1/lib/waterfall_sink_impl.cc

/*

  • Write the header. Make a dummy serialization to avoid padding and
  • alignment issues / d_fos.write(h.start_time, 32); d_fos.write((char )&h.fft_size, sizeof(uint32_t)); d_fos.write((char )&h.samp_rate, sizeof(uint32_t)); d_fos.write((char )&h.nfft_per_row, sizeof(uint32_t)); d_fos.write((char )&h.center_freq, sizeof(float)); d_fos.write((char )&h.endianness, sizeof(uint32_t));

The are 32 bytes of time stamp now before the freq info.

Thanks @wose . Waterfall and spectrum works fine now.

@arope99 Cheers! I got some code cleanup and a few almost ready features regarding decoded data left to do until the next release. This will probably happen during the next weekend.
