If you just want to go from analog to LinuxCNC, have you considered using an ATmega to parallel port interface? The AVR can accept pure analog or some pulsed variety, such frequency counting , PWM or PDM. A dual parallel port PCI card is ~$15, Arduino Pro Mini for $20: http://www.sparkfun.com/products/9218 You could isolate the parallel port pins with a parallel port breakout board. This could run with a real-time component. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
