Hi,
I have successfully compiled comedi for my 2.6.10 brand new kernel (I've
just installed a gentoo on some laptop in order to use a pcm-das08
pcmcia card et my thesis lab).
It looks like working to me (see under). but I cannot do:
comedi_t *it;
lsampl_t data;
it=comedi_open("/dev/comedi0");
comedi_data_read(it,0,0,0,AREF_GROUND, &data);
as shown in the "first program" in the manual. I always receive "-1" as
response.
Need I to configure something more not well documented?
regards,
Jean-Charles
