After fighting for two weeks with the library provided by technologic I decided
to rewrite my own library. The problem was that this tsadclib1624 buffering
systems is not working. I lose packets if I get samples in a continous loop.
With my library now I am not losing any packets. I am not really happy with the
support that I became. The guys from Technologic were able to reproduce my
problem but they told me that right now they did not have time to fix the
library.
Anyway if someone is interested on obtaining my library I could send you a copy
of my code. But it only works for the TS-ADC16 (not the TS-ADC24) it can be
extended easily thought...
