Uwe Bonnes is a main contributor to libftdi and he mentioned to be able to get 15MB/sec between FPGA and FT2232H. http://libftdi.141977.n3.nabble.com/FT2232H-sync-fifo-mode-td2573841.html If you understand German, this might help. http://www.mikrocontroller.net/topic/224615 The following link and AN should help as well. http://www.ftdichip.com/Products/Modules/DevelopmentModules.htm http://www.ftdichip.com/Support/Documents/AppNotes/AN_165_Establishing_Sync= hronous_245_FIFO_Communications_using_a_Morph-IC-II.pdf --=20 Xiaofan --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
