Re: Mac friendly mid-level photometer (?)

bummer, looks like the party is over - maybe i'll leave it up until i
get a cease and desist? maybe compiling into a mex is still ok?

Hi Erik,

Spyder3 does not utilize the same libraries, and cannot be accessed by
drivers for the Spyder2.

Please to not post our SDK documents publicly; they are not public
documents. Our SDKs and and drivers are commercially licensed, and are
not distributed via
GPL. We do not provide public access to our devices, and as of the
Spyder3 SDKs are only providing serialized access to companies that
sign an NDA and follow
our licensing agreement.

Our policy during the Spyder2 timeframe was to provide SDKs to
educational instititions for their internal usage, but it was not to
provide public access to
driving our devices. Sorry for any inconvenience this may cause!

i posted my matlab interface to the spyder2 on the psychtoolbox
wiki so
that others can use it.

i wanted to check that it's ok with your license to have
included the SDK
files you sent.? also, i notice they aren't available via ftp
anymore --
it would be useful to your users if it were permanently available.

will the same SDK libraries work for the spyder3?

i know that the psychtoolbox developers would consider adding
the spyder
interface directly to psychtoolbox, but they would use a
different method
than i did -- they would prefer to link/compile the libraries
directly
into things called mex files -- another way that matlab has to call
external libraries.

psychtoolbox is distributed according to GPL, is that usage OK
with your
license?
