setPumpLaser.c

/*
   program to set analog output

   RasPi connected to USB 1208LS.

   Sets analog voltage for probe laser. Uses Analog out port 0. Final output to probe laser is through 
   op-amp circuit. see page 98.  Page 99 shows calibration data.

   Usage '$ sudo ./setProbeLaser xxx' where xxx is an integer value between 0 and 1024
