Hi there, I'm trying to draw constellation diagram for my tbs6925 card. I'm using s2-liplianin-v37 driver. My question is about the visualization. There is no problem when the modulation is QPSK but when i lock 8psk and higher something happened and the coordinates which i take are not normal. I post 2 screen shots QPSK and 8PSK. Thanks for the help in advance

What app is this?
You can take a look at my app and drivers if you want.

however ... using your driver things are just perfect, you did best job, i've looking for solution for a long time to get FEC and MOD (every second). Thanks for the drivers tree. But i cant understand something - my result from FE_GET_CONSTELLATION_SAMPLES is array of long's couple (imag and real). Should I convert to other type or something elso for proper visualization. Thanks in advance...

No idea. Try doing a
make distclean; qmake
Then rebuilding it. You installed all the dependencies right?

I've tried to rebuild, but without any success. I'm curious is it normal to receive zeros (0) as a part of all array (imaginary, real). For example i have values != 0 for both imag and read, then stops and continue with zeros (imag = 0, real = 0). After this part I receive again (imag != 0, real != 0). Does anyone can help me with that.
