I already had circuit boards manufactured in China but without Ethercat device, the LAN9252 however have an SPI port so this should not be a broblem. The driver cards works and with an Ethercat chip I have a really good communication path. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
