hi.
i m under mingw32 / XP and i do not arrive to talk with vm116 (that works with demo software).
Led showing discussion stays muted…
I m suspecting an error in my way to talk to K8062D.DLL.
It returns me following infos on t:
Opening returns 2
and setchannelcount 33
Here is my code,any suggestion ?
yours,
extern "C"
