simpleccd.h

A simple CCD device that can capture images and control temperature. It returns a FITS image to the client. To build drivers for complex CCDs, please refer to the INDI Generic CCD driver template in INDI SVN (under 3rdparty).

/*

   "Simple CCD Driver"
 
   We develop a simple CCD driver.
 
   Refer to README, which contains instruction on how to build this driver, and use it
   with an INDI-compatible client.
