Hello I'm a student in intership and my project is to make a usb connection with the DE2 card !LOOK: PC (host) -----(usb in serial)---->(DE2, usb device(isp1362)) for Make this systeme I use Labwindow/cvi fort send the data . Quartus II Nios II and DE2 CARD with (a cyclone II) IN the cd I use Cdrom of DE2 card I use the demo Software for understand the functionning of the Universal serial bus ! this is a link with my project http://files.filefront.com/pjt+usbzip/;13633905;/fileinfo.html Look the altera software Send 2 messages add and clear ADD ! http://nsa06.casimages.com/img/2009/04/21/090421042057745026.jpg (http://www.casimages.com) ADD correspond to : ??????? that is the question :D Clear correspond to : 0x55 or 0b 1010101 What is the variable of the data is stock ? what is in the programme ISR.C ("in the link of the project"): bD13flags.bits.DCP_state bUSBCheck_Device_State.State_bits.RESET_BITS = 1; bUSBCheck_Device_State.State_bits.FOUR_RESERVED_BITS=0xcc; Is possible to explain to me the programme ISR.C please !! In the globality my project is the to simulate the communication between the computer and one capteur Of ATLAS detector !
